- In the episode of TYRANIS Customs we walk through the process of designing and building a dual a arm independent front suspension system step by step, from start to finish. We show you the whole process as well as discuss the theory behind the key design decisions in hopes this video helps you to build your own custom go-kart front end! If you've got any questions leave em below!

People watch your videos and don't realize how much time all that actually takes😊 great job though I've got all the tools do it but just no time but definitely gave me some ideas😊
underrated go kart youtuber
Following you here and Facebook, I really don't know how you don't have more traffic. I'm hoping your channel grows because your videos look great!
As an owner of multiple 3203 Yerf Dogs, I love seeing what you do with them. I live like 10 minutes from Kyle @ KJ Raycing and we do a lot of kart stuff together with our kids; look us up if you're ever within reach of the Albany/Saratoga region.....I'd love to arrange a 'kart day' gtg/collaboration
The front look just WOW!
Also love that idea for the suspension once mine explodes or something I might adopt that idea
Start savin up for that welder, man!
sweet, nice job team TYRANIS
Thank you! This was a fun one 😁
Well done! Don’t get discouraged when the plan doesn’t go the way you wanted to, call the audible and conquer and you did just that with the change. Can’t wait to see finished product. When are you taking on others 3203 and build mine.....? Seriously, it looks awesome.
Thanks Biliken! I'm always ready for things to go off script these days haha. As for doing builds for people, thats always quietly been a goal here. Once we button up the karts were working on the plan is to price out what it would take to start crankin them out. After the red kart 95% if the R&D will be done and I'll just have to sort out the numbers. Your 3203 becoming a TYRANIS Custom is a very real possibility though 😎🦖
Don't know if you have access to a lathe but I used 1 inch tube with aluminum bushings pressed into each end and reamed the bushings to fit the 5/8 inch cold rolled bar pivots. The 5/8 inch bars are attached to brackets at each end of the A arms similar to your build. I built a much simpler spindle design. It is basically a 1-1/4 inch bar drilled 5/8 inch end to end clamped between the two Heim joints with a single 5/8 inch shaft threaded on each end. The bar pivots between the Heim joints. the spindle is attached by simply welding it to to the bar. The parts count is reduced and complex fabrication is all but eliminated. I reduced the diameter of the 1-1/4 bar where it meets the Heim joints so it does not interfere with suspension deflection. Like you, I built my suspension as a complete module with rack and pinion steering. The modular approach facilitates future modifications or repairs. Videos like yours are a valuable source of inspiration for other's projects. I went a little crazy on this build and included jacking bolts to adjust suspension height. The lower attachment points for the coil overs can be adjusted in one inch increments to change the spring stiffness. The combination of adjustable coil over s plus adjustable heights allows you to "tune" the suspension without having to cut and weld. Your "V" bend for the upper coil over mount was the inspiration for my adjustable height feature. Visualize your "V" with pivots in the middle and jacking bolts to adjust the end of the "V" where it connects to the coil over.
That is so awesome!! I love hearing about the builds mine have helped inspire! I had inspiration too and it's fun to see it all trickle down into other badass machines!
Just found your channel. Glad I did. Great job on what your doing. Fantastic quality. I believe this channel will be big!!
Thanks Marty! We'll keep the videos comin!
This front end is really a whole hoon. It's also incredibly clutch that you're such a savage with the camera transitions😱💪🎥
I learned from the best 🤓💚

3/4 pipe is 1-1/16 OD , would work well for your bender ....That is why I used 1" pipe (schedule 80 aluminum) all I had at the time was a bender like yours. Wish I could post pics.
That great advice honestly. We since stepped up to a rogue fab m600 so no more issues haha
Could you tell me more about the type of pipe you are using with that bender thanks
Great build video!
Thank you plastic Jesus!
Dude the music at 28:42 makes me think you are gonna get romantic with the buggy. Lmao
Long nights in the garage, a vintage redbull... Things happen man...
The shocks mounted further out on the control arms is recommended to get rid of unsprung weight. Your concept of them having more force further in is correct, but the spring compression is more accurate when mounted as close to the wheel as possible.
That's a great point! I wasn't really taking unsprung weight into consideration here to be honest. Ill keep that in mind for the cross kart tho!
Great job! I have an old Silver Fox cart with single A arm suspension... I want to do just what you've done here! You've given me tons of Ideas on how I want to do it! I have a whole series on my channel upgrading the Silver Fox frame and a 440cc 18hp engine added too! Dual A arms and rack and pinion steering coming soon!
Heck yeah man that's awesome! Bobs and go karts clearly go well together haha
@@TyranisCustoms at my age you can call me old, old Bob! HA HA! It really needs R&P box and parallel tie rods... I saw red Beard shorten the spacing between the ends of the R&P by making tabs the came back along the side of the rack to place the tie rods further inboard.
so your front suspension relies on the welds holding a couple pipes that are prying away from oneanother. drop that V bar at the top of the springs to the underside of the 2 top bars for better support and maybe flip it over so each side points downward.
24:55 Actually the more they lean in the more progressive it will be. As the arms move up they act on the shocks in a more linear fashion. The best thing to do would go cantilever for maximum progression. Your lean looks good now, avoid straight 90s because you'll go over center and it'll get softer as it progresses.
For a better fit on the A arm rotation points why not use solid 5/8” bar stock, weld a cap on one end and thread the other end to just the right length, then it’s not pivoting on screw threads? Great design, I need to convert my old silver fox the same way!
That's not a bad idea! Ultimately I'd like to get more appropriate hardware without threads all the way down, but thats just what I had readily available at the time!
Great video
There's something interesting about off road go karts. Simple yet effective off road. Maybe farther down the line you guys could do a Tillotson 225 (or similar built small block) single seat rally kart to rival these big block yerf dogs.
I like the way you think 😈 There's definitely a small block 1 seater in our future. I drive solo a lot and the weight distribution isn't ideal for performance driving without a passenger...
@@TyranisCustoms Exactly what I was thinking. Something as compact as possible to save weight but still have full suspension. Those Tillotson 225s put out more power and RPM than a 420, and similar torque. Should be fairly even. I'll be watching!
The knuckles should be tilted 7 degrees back at the top for stability, and the bolts dropped down from the top Incase you loose the nut you won't loose the bolt
The Metal Shop starting the same project instead of the 6.5 Tecumseh this Ole Briggs & Stratton 14.5 hp Intek Saddled up to Comet 40 series Torque Converter Mega Power only 305cc farewell Yerf-Dog Hello Mr. Torque Monster
Heck yeah that sounds epiccc
Your lucky tyrannis you are some how in priority above ghpc for me

Video is stellar and good info but the audio is all over the place. I think a cheap lapel mic and consistent audio volume and you'll be killing it. Love the content
At 11:55 the aluminum gas tank in back ground please share the size of it or link to it it's the perfect size I need for buggy.
nice job bud i kept the sing swing arm on mine but put the shock on the hud and added pivot point to the hub to and notched out some plate above the arm for more travel,and a moded poleris 500 out law irs rear end with a ktm 55hp 300cc 2 stroke, iv designed mine way different its ultra light weight and and super simple but a unique design thats different then iv seen any one else do any where.
That sounds awesome! I love seeing how different people approach the same problem! Everyone has their own spin on it and that's what makes it interesting !
@@TyranisCustoms ya i love it i wish there was a place in the world were we all can play and tinker together with all the crazy ideas everyone designs 🙂
Bro your too good to not have a tubing bender. Were about to start manufacturing full karts. Got a jd push button bender with all die. Gonna pay for itself in time
I finally stepped up and got one! You'll see plenty of it in the newer videos!
@@TyranisCustoms nice man I subbed and look forward to seeing them
Those black tool cabinets are sick. Any chance you do a garage tour??
Episode 4 we did a brief walk around but perhaps a more in depth experience is in order one of these days 😎
I have a great idea they have Cardboard bodies u can make the fiberglass it and put it on a gokart.
First, big suprise
🎉
I like what you did. I worry that your eyebrow is a bit weak. I think you need a brace on the ends. I think you missed on opportunity to add zerk fittings and inner grease holes in your A-arm pivots. Is there a reason you didn't go with brass bushings?
I forgot to mention we're gonna brace the brow. I'm gonna work it into the headlight design in a way I think you're gonna dig. And I've seen Redbeard use those fittings you're talking about, I've just never messed with them myself and I don't have a grease gun that would attach to them either so I figured is save that for next time/a future upgrade!
@@TyranisCustoms Wait... You don't own a grease gun? How do you deal with the shame?
@@MegaKencam I hide the pain by building dope karts on CZcams 😉😂
I have that 3203 , is there any simpler upgrade to steering with removing Arms?
hay yall
Howdy 🤠
Not sure if you answered this or not in these comments but do you know what this would cost having someone add suspension similar to this build within my community? Ballpark…?
I don't even know what I would charge unfortunately. Redbeard does customer builds, so far I've only worked on my own stuff.
Hey check out affordable benders if you wanna look at a tube bender
I still can't afford one but they look really good
Thanks my man! I'll check em out!
so I have a perf dog 3203 and the steering on it is tough, like its hard to actually turn the wheel. the front end is stock
I forgot to end the comment with. any recommendations on how to fix it?
I saw your other comment first. Try this video:
czcams.com/video/tcJr_zvzY0A/video.html
Awesome content! Where are you all located? Would you consider doing this to my Yerfdog 3203?
Thank you! We're in CT and that's something we've been considering/ getting asked about rather frequently for a while now. Once ours are dialed in to my standards, I would definitely love to do builds for people, so stay tuned!
Is that sch 40 3/4 water pipe for the control arm?
It's actually 1in chromoly tube. So very similar outer diameter(1"), but much thinner wall(0.065")
Im watching this video wondering why no one has tried to put caster and camber spindles on these cross karts. Check out true racing karts front ends and how the front ends are set up . maybe the suspension is the reason !
I can adjust camber with my heim joints, but never thought of making caster adjustable!
My GS look n to buy t- shirts and logos hes 10 y.o learning to weld and building his first H frame , free axle 79 he's a fan of your work & videos. He can't find your site for purchases of same.
did you guys just the channel ?
We started about 3 or 4 months ago now, so we're still super new!
I’m on Long Island can you help me with mine
I wish haha. Were not doing house calls yet 😂
@@TyranisCustoms lmaooo I can bring it to you I jus need the suspension done that’s all I can handle the rest
IM THE WORLDS GREATEST DETECTIVE 😂
I knew this comment was coming 😂🦇🔎
Wow took one look at the yellow ads dots and said hell naw
I just let CZcams drop them. We're trying to be able to run the channel as our full time jobs eventually and those lil yellow dots allow us to make the quality of content we do and put it out to maximum number of people, for free. That's really the whole end goal.
For reference this channel JUST made its first $100 😅
@@TyranisCustoms you had over 20 ads in a 30min video. if you want to grow your channel you might want to drop that to 2 ads minimum and even then your sht better be good or people will leave the moment that first ad drops. You’ll learn this one day. I wouldn’t even watch p@rn with that many ads and no one else will either
Сколько будет стоить $??
МНОГО 😅
Тебе нормальный вопрос задали. Сколько стоит $?
