Kraton RPM vs Tbone bumpers

[crimsonfancy]

I posted on another thread, T-Bone is much better in lifetime warranty compared to RPM.

I agree and prefer TBone build material, design, variety and from what I know, RPM only provides the single Kraton bumper that I also run.

I had the TBone on my Kraton and swapped it out for the RPM Typhon bumper. Rear bumpers don’t make a lot of sense to me, plus I think they look stupid....just my opinion

Which RPM Typhon bumper are you referring to? I’ve been trying to find a bumper for the Typhon I just ordered but I couldn’t find one from RPM? Any help here would be awesomely appreciated because I really don’t care for T-Bones...

RPM only makes one Arrma 6s bumper. As you know, it will fit all of them because they share the same bolt pattern. I bought a T Bone for my Typhon simply because it doesn't look as bulky as the RPM that I use on my Noto. I made sure to add the cut off and drilled tops of the flat 4mm screws to fill the countersink in the chassis. The issue with T Bone was that they pull the screws out from underneath the gear box. Hopefully these home made fillers will alleviate the issue.

Well I guess that’s I will do as well then. The RPM is just too big for Typhon. I don’t like the “giant underbite” look lol. Thanks for clarifying @Notorious J

I've owned both and both have their share of problems.

Rpm.

• Doesn't look right on the Outcast or Notorious, looks better on the Kraton and Talion(they are being really lazy and won't make a different bumper). Front of Outcast and Notorious body are flat but the bumper is curved.
• Only bolts on from the bottom no support for the front part of the bumper.
• Bumper will break off right at the chassis do to the above problem.

T-bone.

• Bumper is completely flat and does not have recesses for the countersunk holes in the chassis so the screws rip through.
• Upper support either breaks or the screws rip out.

Here's a couple of pics showing how the Thrasher bumper looks, plus the screw heads I was speaking of. I can't take credit for the idea, as it was another forum member that showed us this cool hack. @Jimbobjr or @Mr.Duke I think.

Yep , t bone says if you break it they replace it , I have both rpm and t bone on stuff , wheelies bars are a waste of money , get into flips n stuff , it either breaks or just gets in the way , back bumpers save body's from dragging in half , one things obvious , bumpers arnt for looks ? , but of course just my veiw , after 25 years of addiction in rebuilding these things right out of the box to make a realistic version of what I thought I bought ??? crap I just got a RAMINATOR , and it freegn needs upgrades , again with the ????????

Yeah nothing like the rear of your truck body dragging on the ground, that was the death of one of my bodies on the stampede. I temporarily have the stock wheelie bar on it but I want a rear bumper as the Traxxas wheelie bar is a giant POS that just gets in the way when bashing.

I just installed a t bone bumper and the screw holes where so tight it stripped out all the screw heads. I tried contacting the Company several times to see if I can buy a new set of screws for their slopely constructed bumper but they just ignore me. It also took more than a month to recieve my order. Get rpm. Their part tolerances are much better ?

R. P. M. Is a great bumper system , I live ten miles from t bone , they know I'll come knockn so I get really good service , so far

You stripped screws just trying to put them through plastic holes? Might be you need better hex drivers. Not saying T Bone is perfect, but even new Arrma parts require you to basically create new threads. If you don't have good drivers, any resistance will cause you to strip screws.

I use a good driver tip on a drill , goes in perfect Everytime , I think I have 4 t bone bumpers ? now that I ponder that

In his defense the screws are only 10.9 grade steel, I usually toss them in the trash and use my 12.9 grade screws.
