RPM Rear A-arms for the Associated Pro2 SC10 and Trophy Rat are designed to improve crash survivability over stock A-arms. They started by increasing the amount of material surrounding the hinge pins. Then, they ditched the offset button head screws that prevent the hinge pins from sliding out. Their 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.
The support beams on the A-arms also gained some muscle. At their thickest, stock rear a-arms are about 0.37" (9.4mm) at the thickest point, tapering down to 0.27" (6.86mm) at their thinnest. That amounts to a loss of nearly 30% of their thickness at the outer hinge pins! Not with RPM! Their A-arms are a full 0.4" (10.16mm) thick over nearly their entire length! They only taper slightly at the hinge pins to match the maximum size allowable of the hinge pin bosses. Additionally, the width of their a-arm support beams are beefier as well.
All RPM A-arms are molded from nearly indestructible blend of engineering grade nylons for performance you can trust.
