RPM Rear A-arms for the Associated Pro2 SC10, Trophy Rat and related models are designed to improve crash survivability over stock A-arms. We started by increasing the amount of material surrounding the hinge pins. We then ditched the offset button head screws that prevent the hinge pins from sliding out. Our new in-line screws are a tried and true method of improving strength simply by eliminating extra holes in the a-arms. Fewer holes means fewer places for cracks to start.

Furthermore, the support beams on our A-arms also gained some muscle. At their thickest, stock rear a-arms are about 0.37” (9.4mm), tapering down to 0.27” (6.86mm) at their thinnest. Not with RPM! Our A-arms are a full 0.4” (10.16mm) thick over nearly their entire length! We only taper them slightly at the hinge pins to match the maximum size allowable of the hinge pin bosses. Additionally, the width of our a-arm support beams are beefier as well.

All RPM A-arms are molded from our nearly indestructible blend of engineering grade nylons for performance you can trust.
