Great video! Can you please provide a link to the blacker washers assortment you mentioned, instead of using a vise on an rpm bumper for pieces?
Direct link to washer kit

This washer kit is also extremely valuable regarding this video mod suggestion:
czcams.com/video/GD10n3zfAxk/video.html
Regarding using the smaller plastic washers as a fill-in instead of the piece that I ripped off of the RPM bumper. Just note that the pieces from the RPM bumper fit perfectly and provided an exact space fill in. I really wish I could’ve found something similar to its shape sold as a separate peace. I actually looked for quite some time. The washers being that they are flat will work as a fill in however you have to be aware that the pressure of the screw will squeeze it in the place and almost remold it. You’ll want to use one or two of the smaller washers. It’s less than a perfect gap fill in, however it’s better than nothing.
Thanks for the tip! I just ordered the rpm bumper yesterday for my typhon. I am going to do this. Thanks again! 👍👍
Another great curious solution buddy! I too prefer the RPM bumpers so will likely try this...
Appreciate the shout out my friend.... Been my pleasure following where your curiosity takes you. Love what you do!
See ya round brother
Good for grass and dirt YA. Good ideas man. ❤️👊😀
Had to come back and check this vid again. I still am upgrading my truck. 🙂
Another great video! And the shoutouts are to some great people for sure!
The reason im in that hobby is cause of Rich, Eric and Vas.
Thanks also for you Randy, giving us that great info 👊
Great idea bro!!!! I will definitely b doin that to mine!!
good vid, imma try that on my v4 talion pos bumper!
Wow man thanks for the link and this is a fantastic idea. If my idea of my EXB bumper mod to suit the M2C hinge support doesn’t work, then I’m gonna go back to the RPM and do this exact mod. Awesome stuff.
Update: my EXB mod works great after one other small mod using these exact countersunk washers. They are awesome. I also used them on an old RPM bumper I had on the front which I have now put on the rear using these washers also. Thanks so much again bro on finding these washers. Highly recommended. 👍🏼😃
Good video East. I'm a new owner of an arrma typhon and you make some quality videos brother 👍
Great video!
Great idea Dude 👍
Thamk you East Tactics
Anytime my friend!
Nice hack with the with the Timerman washers brother!!
Thx!!
One of the reasons the screws are pulling through is that there is a gap under the bumper between the chassis and where the screws used to mount flush. You used the part that came off the bumper to pack this. Try using "Milliput". It is a two part epoxy modelling clay that sets hard. It's easy to work and provides a perfect fit.
Nice info on how to stop the bumpers ripping out, this is an issue on all the bumpers - my Kraton EXB ripped out as well, nice find on the washers 👍👍 im glad you are now a convert to building your own fans and not falling for the NTF price tag, i know we had a bit of a debate on this with my how to build your own NTF fan for cheaper :)
Yeah… I... like you, want to show people a better way. Especially now that I know that the fans that he’s using have a build weekness. Details in the next vid.
One thing I am grateful for regarding my purchase from NTF though is that I’ve got all the miscellaneous components to attach the new ones.
I have serious Question for u on the 4s kraton slipper Clutch to tighten the slipper Clutch i just pull back THAT long black pole underneath the Red 1 the black pole WITH spring in it like the 4s Arma senton same set up then take pole out of 4s kraton then theres a liittle red piece at the very back of Truck on the left hand side use the L shape keys make 1 full turn to the Right and its tighten up again watched a video where guy did it with his 4s senton same setup like i said before so Iam i right or wrong with tightening up the 4s Arma kraton 110 the same way?
Please Tell me Iam right!!
If that's THE case it will be pretty easy once i get used to doing it
Troy I’ve never messed with the slipper clutch in the 4s. Hit up Razor RC with this question my friend
The only thing that my concern is with this approach to fixing this problem is now since you've added the washer your screw doesnt lay flush or just a hair below the plastic, witch now the screw is going to grind away the head off when the chasis bottoms out now.
True, but the trade off is worth it. If one or two gets too warn…simply toss in a new screw. But I hear ya. Thx for watching 😎
THE bumper i have now is THE small bump it Comes with when u THE 4s kraton
The RPM bumper is an excellent upgrade. Lets just say if I wasn't rolling with the RPM on that hard concrete nose dive... it would have likely jacked up my whole front end.
I believe you are supposed to keep the factory bumper on and install the rpm over it
Negative my good man. The factory bumper actually prevents it from a flush mount. There’s a special bumper piece you can pick up in this package that you’ll actually want.

I need one of those rc jacks/lifts😏
Yeah they’re awesome, you do want to make sure you find the one that has a taller beam. There’s another one I think it even the same brand that a lot of people end up accidentally picking up and it’s got a metal beam that’s like 2 inches shorter which is not ideal.

@@EastTactics thanx bro 🙏
Great video yet again 👍
Question though, wouldn't the screws need to be replaced by longer ones seeing as they now stick out a few extra mm?
It wouldn’t hurt if you had 4 mm screws laying around that were 1 or 2 mm longer. However just 1 or 2 millimeter doesn’t really make much of a negative impact on the bite into the housing.
@@EastTactics @simonthomas13 extending the screws is a very good Idea ! maybe not so much importance if like Randy, you have an upgraded aluminum dif housing, but into plastic, every mm will count, as by strengthening the screwhead-to-bumper pull through connection, youre moving the pressure to the next weakest point (the plastic diff housing threads in a standard Unit) so losing 2mm+ reduces the connection strength considerably. That's not to say it will definitely pull out the threads, but, as what you are doing is to improve the existing set-up, leaving any sort of weakness from the 'standard' is counter-intuitive & a negative point. I've seen some stuff suggesting there's actually quite a few mm unused in the housings with the standard screws as it is , so longer screws would definitely be an improvement.
Great set of vids by the way 👍👍
As is covered further down though the screw heads are sunk into the bumper to protect them from physical bashing and wear, or leaving a sharp edge where a sudden stop could occur, but I appreciate they're only fractionally proud. Maybe swap the screws out for some titanium ones for added sparkage when and if they do ground out LOL
@@iwantblue491 I agree... longer screws (2-3mm) is a good idea. Rpm ships the bumper with longer screws though. 👍👍
I’m down for checking this out. 👊😀
Got less then half way through. I want to add that doing this will always have the screws smashing the ground first / all the first will slam into the screws.
Would that be a bad idea.
I say that because my RPm bumper which you know has deep counter sunken screws for a reason.
I replace mine when the screws just start to get scratched up from the bumper wearing out.
Honestly... you make a pretty good point. That does explain probably why they are counter sunk in like that. I'll pay really close attention to this. Honestly I don't mind the screws taking wear. ill just replace them if they get too bad. But the idea of the ground smashing the screws upward and damaging the diff house, seems plausible. I myself have the aluminum RPM diff house's so I feel it's probably pretty unlikely. Another thing that gives me a sense of ease is that the washer themself, being metal will act as a protector of the screw from shifting upward from a hard smack. Will report if an issue arrises though thanks for the heads up.
I still want the Bumper for my 4s kraton doing some upgrades now on it just minor 1s for Now New 4s kraton blue and white body like the red 1 o have on Now getting New gears put with shims in thats about it for Now until After New year Then i want to go All Metal gears and New set of back flips Tires i will have to see how my money is first start New job in January Care taker work hopefully Everything works out real bad year for Everybody this year
GodBless Everybody And stay safe peace out.
@@troyflanagan4237
👊😀right on. Good info. Thanks bro 👍
@@EastTactics
I see. Ya metal diff cases help. I might get GPM or hotracing Center diff case for my first metal part.
Where do you get the body mounts ? ? ?They look like the ones on the traxxas trucks . .I would like to change mine to that . .
Awesome! Here’s the info on that
czcams.com/video/OcQRt1bpwA0/video.html
I bought wheelie bar for typhon 3s tbone racing and there is a curved piece of metal in the package. Do you know what it’s for?
Looking into it for you
My RPM bumper is on the way, but I have sheared off the screws from the original bumper, and having trouble getting the aluminum pin holder out, so I can get ahold of the sheared screws... I believe 1 if my screws is mushroomed out just enough to lock it in.
I'm wondering if that original aluminum block is just free floating? Should it just slide right off if the plastic pin holder is removed?
Sry for the poor inflated description:)
Edit: it was a mushroomed and bent screw, got them out:)
30 foot nose dive at the skate park broke 2 screws, this thing is a beast😬🤣
30 foot nose dive at a skate park… That’s awesome. Were you planning on implementing this modification by picking up those Timmerman washers?
@@EastTactics ofc:) Another great idea, with experience and reason behind it;)
Spend 50 cents to save $15
So if there not tore just add a washer correct?
If you tore through one of your bumpers I would do away with it completely, contact RPM and have them send you a new one for free.
What I recommend, once you’ve gotten your new RPM bumper Is that you first lay down the bumper. And then use either a plastic washer (or even better, take advantage of those torn wedges from the broken RPM bumper as a space filler) and then put down your counter sunk washer.
Either way what I’m getting at, is that you do want to fill in that small space with something. If you don’t have any of those little miniature flat washers, or can pull those little wedges from the old bumper, then dig through your parts graveyard and see if you can find something tiny to fit in to fill in that gap. I noticed myself that I had a old RPM skid plate that had the same wedges that I could rip out using my voice. The point is I just don’t recommend having the air gap between the countersunk washers and how deeply sunk the RPM bumper holes are. If that makes sense.
I Try not to drive on cement to prevent major damage so its screws and washer what size screws and washers to do this work?
When picking up the RPM bumper it comes with extended length M4 washers to account for it's thickness.
Thanks for information
Good 🌙 night
How u like those avid bearings
I think they’re great, Haven’t had a single issue.
So with a new rpm bumper, do you still need to use the plastic m4 washers? Or just the metal one under screw head.
You’ll notice that I ripped the pre-existing plastic from the old RPM bumper and use it as a spacer. If you don’t have the ability to do that. Then I would suggest using a plastic m4 washer. So you’d slide the metal Timmerman washer on the screw first and then you would put the plastic m4 washer next as the spacer
@@EastTactics gotcha, i tried the m4 washers but they dont fit well in the hole. And makes the screw stick further out. Wonder what will happen if you just use the metal washers and thats it? I seemed too tighten up fine but wanted too ask b4 i run it lol.
That’s odd I really thought the M4 washer would get squeezed into the gap by the pressure. Without issue. Is it possible to put smaller washer, or something there. Ideally you want to fill that gap that way any major impact will utilize not just the Timmerman washer as rip prevention but the thickness of all the material combined with the timmerman washer for the maximum strength.
Either way, if you bypass any spacer or material I still feel that the upgrade is better and stronger.
@@EastTactics i have an m3, that may work i just will try to make the hole bigger for the screw, but i think the m3 washers will actually sit down in the hole. I guess that'll be ok? Or would you want it too act as a washers and sit on the outside of hole?
Put the M3 washer or whatever spacer that works for you Down into the RPM bumper first, and then the Timmerman washer on top of it. Put the screw through it
U need game changer fans
That's the bumper i want for my 4s kraton a stronger bumper
Yes, for sure.
Its Even hard just getting waiting on my New gears this week and my New 4s body at End of month when i first bought the Truck back in may i damage my slipper Clutch by hitting a cement block in a school parking lot just took my eyes off the Truck For a second watching some lady WITH her dog off the leash i thought the dog was going to start Chasing it and before i knew it i turned my head around to watch the Truck didn't hsve time to stop and bang pushed the slipper Clutch back into Engine i had till the End of August before it WAS finally fixed and ready to drive it cause of the major slow down of Companies and manufacturers Covid virus
Buy i forgot that word
Does rpm make a front bumper for typhon 3s?
It doesn’t look like it, I went to RPM’s website and they do make a few products for the typhon 3s. But it’s not a very comprehensive list of items. Here’s the link
www.rpmrcproducts.com/shop/?filter_make-model=arrma%2Ctyphon-3s-blx
@@EastTactics twine number. One says basher other says racer, protector and guardian. Are the different?
Twine number? I’m not sure what you’re asking? Can you drop a link so I can see
@@EastTactics when I go to google and type in t bone bumper typhon 3s. I noticed 3 different bumper names pop up for tbone website. The guardian the protector and the racer. I loooked basher up CZcams and it comes with a metal shield for under bumper
@@EastTactics czcams.com/video/Y0F6L-JIJCg/video.html
you screwed those screws down way to tight and pulled through the plastic don't go so tight and it wont rip out ever again ,,little more than snug is all it needs
You make a great point, overtightening it’s definitely a bad idea. However trust me I didn’t overtighten, that was just a serious nose dive on some serious concrete. I’ve always been extremely impressed with the RPM bumper... still am. Now I definitely have confidence that if I duplicate that type of a nose dive again, it won’t rip out. I did a similar thing with my battery tray ripped out. Used washers to lock that sucker down. Battery tray ain’t going nowhere now. Bash on brother!
Rpm have been having issues lately 😕
Na, I still stand by this bumper. Aside from the new EXB bumper (which I will eventually get and test) this one is still the best out there. Most nose dives wont rip the under plate off. That nose dive was epic!
@@EastTactics I like the bumper too but I think they need to do a lil updating to the parts maybe a 2.0 version of some the things that have been out for a few years
@@onemansvideos2134 I would love that.
