This is an optional RPM Mini Front Bumper. This bumper is compatible with the Associated B4, T4 and GT2 vehicles, as well as the HPI Firestorm family of vehicles. Race oriented Associated GT2, B4 & T4 owners prefer lightweight, yet effective parts. Weighing in at a mere 5-3/4 grams, it is small in size but big on performance. This mini bumper is 30% thicker than the stock skid plate providing tons of extra skid and impact resistance. The RPM mini bumper extends in front of the vehicle and curves up into a 2” wide bumper that actually performs as a bumper. It protects both the chassis and the hinge pins from frontal impacts and acts as a low-friction skid plate. RPM mini bumpers also use all four bulkhead mounting screws to disperse impacts over a larger area reducing transferred impact forces by over 50%! As a finishing touch, RPM mini bumpers have recessed mounting holes so all those nasty scrapes and crashes will be absorbed by the bumper, not the screw heads!


  • Lightweight design (5.75 grams)
  • 30% thicker than the stock skid plate
  • Reduces impact forces by half
  • 2” wide bumper protects the chassis and hinge pins from frontal impact
  • Acts as a low-friction skid plate

Tengo montado este bumper en mi B5M y encaja perfecto, me gusta más que el pequeño bumper que trae el coche de serie, lo recomiendo.

I have assembled this in my B5M bumper and fits perfect, I like the little bumper car that brings the series, I recommend it.

These are awesome. I have used them on a B4 and also an HPI Blitz buggy conversion. Never broke a bulkhead (as other review reported) and I have thrown some serious crashes at it. If it can handle the weight and abuse of my 60mph Blitz, it's gonna do great on your B4/T4 etc

Works well and I don't see the issue with 4 screws. If you don't like 4 you can still run 2 under it and 2 for the bumper. The bumper kicks forward more and works better for RPM's from Arm kit for the B4.x

Very solid, it's perfect for protecting the body, it's also good for the Team Asso T5M

Not a bad bumper but it uses 4 screws and the stock one uses two, I think with this one using all 4 screws it puts to much force onto the bulkhead which didn't fair well with these set-up. If you are a good driver and hitting things is not a usual for you then these would work, but if you crash like my kids do this one may give you problems.
