I have an aftershock 3.5 that I am trying to find a good rpm bumper for. I wonder if I call rpm they would be able to help me out.
good luck there, tho it wont hurt to try.
unfortunately i dont own a 3.5 model to test parts on[&o]
there are many bumpers for 1/10 short course trucks, but im not sure how they would work on a 1/8 SCT like the aftershock.
you could try contacting t-bone racing. they make a large selection of bumpers(high grade stuff to)
i know those guys to testing on models, and they may have a redcat to test with. even if they dont, you could give them the dimensions of the mounting holes on the aftershock, and they may have something that will bolt up.
