Welcome to The Fab Forums. My name is Kyle Voss and I produce Custom Motorsports Fabrication content of all forms for you. Carbon Fiber, TIG Welding, Metal Shaping, Hot Rods, Muscle Cars, Custom Choppers, and everything in between. I work hard to bring you new content on a weekly basis.
Here are some of the builds you can find on this channel.
I have built several Chevy trucks on this channel. The first was my 1964 C10 named Crown Spoyal and the most recent C10 truck project was the 1969 I currently have named the Black Pearl.
I am also finishing up a custom twin turbo Ford Mustang build I call the Gray Goose. It’s a 400 cubic inch Windsor style engine with twin 70mm turbos. I am hoping to make around the 1000 horse power mark to the tires on this particular build.
Last but not least is the one off custom hot rod build called the Bibbster. This is what I call a modern day hot rod. It’s made from an old Ford Mustang foxbody, but made to look like an old school open wheeled hot rod.
I also feature other fabricators and shops like Cutworm Specialties hand formed aluminum wide body kit for a BMW e46. Jeb Greenstone has also built a twin turbo, coyote powered model A style hot rod from scratch, and is currently building a Toyota TE72 wagon drift car powered by a 1UZ Lexus v8. Jeb’s custom fabrication skills are fun to watch and always make for good videos.

Just so you know. A good rule of thumb is to tack the housing ends on dead last. Any gussets or additional weld on parts should be completely installed before you weld your ends on. This allows the tubes to warp with out any misiliment to your axles.
nah...I have thrown ass loads of heat to these things and re checked them afterwards. Never have any move.
Man love your videos, saves me so much time searching numbers
The majority of YT 8.8 narrowing videos show someone cutting the tubes, which is the cheap (as opposed to inexpensive) way to do this. As Kyle said the point is not just to narrow the housing but to get rid of the c-clips and add larger bearings at the ends. You're likely going to buy axles anyway so spend the extra time and money to do it right.
Perfect timing! I'll be shortening a diff next week and changing the flanges , well attempting to haha this cleared up the question " how do I keep it all aligned " cheers bro keep up the great work 👍
Awesome Video! I wish this video was around when I built an 8.8 back in 2008.
Great video exactly what I was looking for beautiful welds!
I did the same to my 8.8, and built a jig to hold everything in place. Hardest part was finding a bracket for stock brake calipers, but now you can easily find them on Jegs. Keep it easy.
I used the stock brake brackets and calibers/ rotors. When you get axles tell them your running stock brakes and you will be fine
Thanks, some good info on the 8.8 rearend. l like the look of the Fronius welding jacket.
lol thanks
Awesome content your buddy has a few toys in his garage cool
Super Awesome!
Actually the reason a 9 is the preferred rear is that gear changes can be done at the track in 15 min and an 8 has to be torn down to change them. They are also supported by gear manufacturers in many forms, ie lightweight, heavy duty off road and virtually every gear ratio you can dream up.
cara...você tem ferramentas super....esta maquina de solda é um shwou....super
Thanks great video!
Good work Kyle
thanks
I've learned so much from ur videos 😎👍
glad I could help
Very Cool!
thanks
sick fox is such a badass build. been following him for awhile its a small world. just discovered you channel man keep up the baddassery man!
yeah he lives local to me...super nice ride
welcome to the channel
excelente trabajo muy bien reforzado!!.. saludos.
thanks
I like this guy. Seems legit
Did this to my car years ago . Used 2 rigid emt and some plate steel and a tape measure. Worked out great . Do work son !
What axles do u use when doing 9in ends
Customer work is going to be very cool
What filler worked well?
"Go do work. SON!" Love it! :)
The real difference between the 8.8 and the 9 inch is the fact that the pinion gear is supported at both ends. So the 9 inch is way stronger than the 8.8. The 8.8 is still plenty strong though. I added those ends to my 8.8 so I could run a spool. Much better than the C clip eliminators.
yeah I could see them having less pinion deflection. It usually the ring gears that fail though.
I have seen an 8.8 pinion snapped but not on anything I own. My 8.8 will do the job unless I get carried away with my 4.7 L Teksid build ( AKA John Mihovetz's Mustang ) but I would need to win the lottery. :-)
Boom! Hey Kyle.
yo
I would like to see if that alignment bar still fits right. Nice video.
like butter
what's up.. I'm Brandon from phx, AZ. your video's are inspirational. Thanks..
thanks
i plan on doing that to the 8.8 that im building for my car ,where did you get the alignment tool? thanks for great video
🤘🏻
yay!!!! i see a dodge durango too, my favorite suv lol great vid!!
thanks
What wire did you use to weld to that cast pumpkin? Won't the weld break right around the cast?
so now you just put in axles from a 9 inch with the same spline count as your original 8.8 axles? Is the axle length gonna be perfect? and what about the drum brakes that would be present like on a f150 ? I have a passenger side axle that slides into the diff to far and causes the c clip to fall halfway into the diff while still halfway holding the axle( scared its gonna throw the axle and c clip gonna tear up gears in diff) im thinking about doing this to my f150 just worried about how those axles and brakes all line up
nice work son!
thanks
I prefer the 8.8 I'm in the process of putting a 3.73 posi lock 8.8 from a ranger to my 86 s10 with a 10 inch deep wide with cooper cobra's, had relocate the spring perch and shock mounts.
Are custom length axles required if you are installing 9” ends?
I originally did a JY 8.8 swap but now I think ill look into that 9" end swap for another axle setup.
awesome
What welder were you using to weld the housing ends Up. Thanks
What filler rod did you use on the tubes to the center section? Is that an ER70S-6 or some other rod? I assume that's the same you used for the tubes to housing ends?
Don’t you think the disk brake calipers would prevent the axle from coming out?
When doing this Mod on an 8.8 which axles do you use, and are the new housing ends the "New Style" Big Ford style?
Yes strange H1137
9" ends are the way to go to run 35 spline axles
What size axels did you go with?
on your fox are you running a upper rear control arm relocation bracket for the instent center ?
I am not, I know a lot of guys do though
the song in the middle and the end???? who is it?
This is awesome! I'm in europe. We like our multilink independent rear suspension over here. Is that something that you would possibly consider as a future upgrade?
For drag racing the straight axles are the superior setup...would for sure go independent for and kind of grip setup.
I have no experience with the 8.8 [we did not get them here in Oz], the C Clip axles do not inspire confidence but as for the rest I guess it depends on what gear sets are available. And what size the pinion ends up in shorter gear sets.
The 9" has not been made for 40 years, it has always been an overhyped thing. IF you throw away all the Ford parts and fit aftermarket they are ok, BUT the pinion is too low and that drags horsepower big time and fries the oil as well. And they are so bloody heavy! In comparison too a B/W Dana 78 series they are 35lb heavier, all unsprung weight.
I used them in road race car for some years and never actually broke one,, but regular inspection was required and I junked a couple of gear sets as they had cracked.
The clip shows '9" ends" but which bearing? Tapered bearing? double row bearing? large diameter or small as they had several styles. And the old Ford axles have a very bad habit of cracking outside the bearing at the shoulder the bearing pushes up too. In mine I used GMH axles cut and resplined as they are far better material. Though I did break one of those outside the bearing as well so cracktested them regularly after. Though it was probably the axles street use before that did the damage. They were from a 1 ton ute. But for any racecar a floater is the only way.
As for those reinforced housings? Really use some engineering sense. Using very wide wheels with huge negative offset is plain stupid. Make the axles longer and use a central or better positive offset wheel and you do not need any of that reinforcing wank except for off roading,,, maybe! A longer axle too has more area to 'wind up' and not break like the ultra short ones favored. Painting a line from spline to bearing will show eventually how much they will wind up before breaking.
What size is your ceriflat? I’m torn on the 2x3 or 2x5 or 4x4
I think mine is a 3x5
I'm going chev corporate 14 bolt with 10.5 inch ring gear on my next build .. you wouldn't be breaking on of those anytime soon.
As always good info, I may have missed it but when can we see the new shop
building one now
Need to have that housing checked for straightness after you welded those gussets on and..welded the tubes to the housing..
The 8.8 may not be as bad to bend..
But a stock 9"housing is horrible to move all over place after welding
Kevin Luck totally agree! Housing ends should always be done after any other welding on the housing, brackets, braces, etc.
straight as it gets...
More than likely is plenty enough straight to never cause a problem but I personally prefer to weld on housing ends last. And also we use a 1.25”alignment shaft for maximum stiffness to ensure perfect alignment.
@@lesgray3355 i agree.. we use a 1.5" bar because we actually had a rear end redo over about a half inch tweak we missed on a crown vic rear going on a buggy.. because it was so long one of our guys could feed in the rod so it looked ok. 😕😔kept pulling and couldn't figure it out or fix it. if it's simple you missed something. other then that hell yes a stock 9" isn't worth the trouble an 8.8 31 sp with 9" big bearing ends beats a 9 everytime.
If you do the housing ends last then it will be straight.
Im sure its in one of your videos just couldn't pin point it but what size fuel injectors are you running in the goose? Im building a similar setup
85lbers right now
Love that square body dually. When are you gona make a video of it?
I have a few videos on the channel of it....going to be doing more to it soon
What rod did you use to weld to the cast center section?
er70s-2
Hey kyle. How would you measure for the axle shafts ?
every combo is different. The manufacture will let you know how they want you to measure for them
how did you index the flanges before welding?
came here to learn this lol
I have a question on 302 the wrist pin is pressed into the rod and swivels there? or is it pressed in the piston and swivels on the rod??
I think they are pressed into the rod from the factory
Awesome installation Kyle! I need to do this to my 86 GT too.
Any problems or special instructions for welding to the cast center housing?
Also, do you think there is enough spline length on 8.8 axles to be able to cut 1" off of each side?
If you have time to answer thank you and I appreciate it. If you don't, no sweat.
Robert G If I remember right, when I did my 8.8 build there was about another inch of spline left on the shafts. You'd be cutting it close, that's for sure.
Tanner S., Thanks for the reply, I appreciate it.
I have done a bunch of these and I've never had to do anything special when welding the cast housing....It is a little tricking with all the contamination though.
I have cut an inch off some stock length moser axles in the past and there was plenty of spline
Thanks Kyle, I appreciate you taking the time to answer my questions.
Nice work I thought you would have had a better fit of the end of the Brace bar ( this is not a cut down of your work) than I see it's not for your car. I still think your weld are second to none you are getting pretty darn good "SON"
that fit was like that on purpose
Cool video. What filler rod did you use?
er70s-2
I was wondering if you would get your hands on that car. Guy up in my area painted it, that car is super clean!
Im sure I will see it at some point....just doing the rear now
I always thought the 9 inch was more desirable for the pinion support and no cast in the housing just the 3rd member.
It is, but sometimes you just have to work with what you have.
It is...I didn't say the nine inch isn't good. I didn't even say the 9 inch isn't better. I was just trying to make the point that the 8.8 is a very strong rear and in most cases it isn't worth the upgrade.
The 9 inch also has much more friction/drag because of the big offset from center. The use of a good cover with the cap supports and some billet caps the 8.8 is a very strong unit, after all it was basically copied from the chevy 12 bolt
The housings are cast steel not cast iron. Everyone thinks because they are cast the are weak but they are very strong
So 9 inch and 8.8 axles are the same diameter? Or your using 8.8 axles with 9 inch bearings??
Disc brakes do not need a c-clip eliminator. The caliper over the disc keeps the axles from coming out.
yeah but not without potentially locking up the rear wheel
Hey, so I paid to have this done. Here is the thing, I changed out my rear studs last week and my axles basically came right out. Just unbolted the bracket to the caliper. Is that the only thing holding the axle in, it was this done wrong? I would really appreciate the answer. My life is dependent on it. I liked and subscribed. Thanks
What size tubing for the braces and is it mild steel or chromoly
its was 1 inch chome moly I beleive
Great video! Why have i never seen that 2 door dually guess i missed it...Very nice ive been keeping an eye out for one of those...
Not sure how you have missed it, its been all over the channel. Its a 4 door
The Fab Forums. Awesome! i haven't been a subscriber to long but it's a great channel. I'm with a friend this weekend in a 74 Crew cab chevy....
How do the 9" ends solve the C clip issue?
The axles are now bolted in with 4 bolts, no more c-clips retaining them.
Bing difference between the 8.8 and the 9 is with the smaller ring gear and pinion only 2 teeth mesh at a time and with a 9 inch 3 teeth mesh at a time. It's not just the axle bearings.
Where is the video on the 8.8 narrow and ends cut off?
Looking good!! Never mind the haters.. hey what's the song at the end ?
If you put a rear disc brake conversion....it will keep the axles in the housing should a c clip or axle brakes
still other issues with the roller bearings
Was that a Mustang 8.8 with 2.8” axle tubes?
What kind of amps did you use on the ends?
not sure....under 200
The Fab Forums thx just wondering of my 200 amp tig would be up to the task.
Im guessing it uses 9 inch axles also? Could you do that with a mig?
yeah you could mig it for sure
The MIG welded ones must be the cars on CZcams in fails video's that tear the whole rear end out on the launch from the line. I have done one using MIG. You just have to be careful about your welding.
song artist please
the 9 inch ends u had put on are those the 9 inch big ford old style i thnk thats what i want to do to mine
yeah
Only thing you give up is the nine inch removable third member. Not many people have the need to use multiple gear ratios anyway. The 8.8 is strong and already fits the hardware in the car.
yeah for sure
Are they strong enough? 2 words to look into beater-bomb. Lol. Still rocking 4 lug. Been around them all my life. Axles may break. The 8.8 is damn near bullet proof. From us running 2-300 all the way to day 1000+ buddy is putting down 2400 on small tire with one.
yeah for sure
I know y’all are doing this for drag racing but I wanna put a Cummins in my f150 but first I’m beefing up suspension and my axles would this work on my 8.8 swapping over the 9in ends
yeah
Where would I get axles for it? Any website Info would be awesome
@@thomashunt7717 you can find everything you need at either Strange or Moser
This is so obvious,, for all the work put floating hubs on the housing. Axles are available in 1/2 lengths.
Would be awesome if you could share who the artist(s) are for the music. ;p
tanx !
welc
Good work, Kyle. I've never looked into it, but always wondered about the difference between an 8.8 and 9" (other than the obvious .2" lol). This video summed it right up. Thanks for showing the alignment tips.👍 Looks good, man! Also, I may have missed it, but who is the kickass song by? Thanks.
thanks....the music is some copyright free stock audio. Not sure who did it
I have a question, when you weld ford 9 inch ends on an 8.8 rear axle do you use ford 9 inch axle shafts then or keep the ford 8.8 ones? trying to figure out if i do this and narrow a rear end from an explorer if i can then use cut to length aftermarket ford 9 inch axle shafts to make it all work. I figure if they are all 31 spline it should fit but im not totally sure and cant seem to find an answer.
when you order the shafts you just tell them it has 9 inch ends on an 8.8
Ends go on LAST!!!!...Tacked or fully welded.
yeah I guess if your worried its gonna move or dont have a way to check it after
For the offroad world the 9 inch housing is stronger than the 8.8 but i have swapped alot of 4.10 lsd 8.8 in jeeps over the years because they are alot stronger than a dana 35.
yeah I could see the housing being way more useful in off-road applications especially when it comes to gussets
Who makes those 9inch ends?
Those looked like Strange ends. The are the shortest ones I've seen. Allows the most width to be cut out. H1137 is big ford 9" pattern and H1138 is original 8.8 pattern. Let's you use stock mustang brakes.
@@jgilbert4756 sweet thanks
How long did the front pinion bearing last? I can't see it lasting very long as it looks like you welded the brace where the bearing sits in the housing.
Why spend the time bracing the rear if you're going to use caltracs? This is my particular app.
caltracs ??...wont be using caltracs. What would give you that idea?
I'm saying for my truck, I'm using them.
@@davidtaylor1384 gotcha. Caltracs are used to minimize axle wrap...not for what these braces are used for. These keeps the axle tubes strait under extreme loads.
Always weld housing ends on last after all welding on housing has been done! Where you welded those tubs on right at the pinion bearings is a NO NO!
I need the buggy
everyone needs one
....waiting for the “you can’t weld to cast” comments
yeah I have already got it
I have never had any problem welding to cast steel. I believe i used 7018 stick but i probably have done it with flux cote dual shield wire. May have even used MIG hardwire before. I think i always preheated if i remember right.
Needle bearing? That’s a roller bearing. You could just buy a Moser M88 axle housing, all of that is done with bigger stronger components including much bigger main caps and hardware.
"If the C-clip breaks or the axle breaks the axle can just slide out." Okay, so I get that the C-clip is the retition system for the axle and the statement is absolutely true with drum brakes. BUT when running disc brakes... The axle is behind the brake rotor and what's over the rotor? The brake caliper. Now granted the brake caliper's purpose was never to retain the axle, but in the event of an axle break wouldn't the caliper prevent the axle from sliding out of the housing since it sits over the brake disc which the axle is behind? You can't get the axle out when disassembling without pulling off the caliper.
yeah
c clips with disc is even worse.. broken axle locks up by wedging the rotor into the brake and spins the car, sometimes it flips.. there is a reason why many tracks are saying no c clip and no c clip eliminators. just weld on the ends and be done lol
When are we going 2 see more on the jaw breaker maybe a update !!!!
not sure....I will have to get with Jeb
A 8.8 is like a copy of a chevy 12 bolt.
Seems like a simpler solution would just bolt in a 9 inch, but that's just my opinion.
its really not
So question. I have a 2007 Toyota Sienna LE AWD MiniVan. I’m building my rig for rally racing and off road with rock climbing in mind. I need a lot more flex and reliability for the rear end. I have a loaded axle beam suspension set up. That’s stock. Also, a differential with cv axles. I am looking for a axle or differential that has the capability of a air locker. Dual brake caliper set up. And sway bar hook up for when I’m going super fast. And of course sway bar disconnect system that’s easy to do for rock climbing. My engine will make 400HP + and 350+ torque. It’s going to have a SuperCharger and will be hooked up to a E352F 5-speed manual transmission with a matching T-Case from a 05 RAV4. Apparently I have to keep the 2.929 final drive that the rear differential has! That’s because the 4.14 Something Final Dr. that the transmission/tea case has apparently the rear axle has to be lower than that I don’t know why but that’s what everyone is telling me. If that information that I told you do you by chance know of any differential or axle I can install for the rear end? Thank you.
If I’m not mistaken on my 04 the brakes would hold the wheel on if an axle were to snap
you are probably correct....anything with a rear disc
Is that
What about the brakes on rear
Uses nine inch brake brackets
I’m doing 8.8 with 35 moser. Sorry but this is my first go at this I’m having a company do the rearend and I’m sorry but could u be alittle more detail like what parts exactly. Man any help I could get that would be greatly appreciated. Love the videos keep them up
@@MichaelGreen-ox4lp yeah you just basically cut off the 8.8 housing end and weld on some 9 inch ends. The weld on peices can be purchased from companies like moser or strange. This mod just let's you use a 9 inch style axle bearing versus the 8.8 c-clip elimnator type of bearing. As for brakes you will just order the 9 inch brake brackets...companies like strange, wilwood and aerospace have options.
Thanks man
The 8.8 is a good rear end and with a very small amount of machine work on the pinion you can run a 12 bolt chevy ring and pinion in one which gives you a lot more gear ratio options in a pro gear.
