RPM Rear A-arms for the Associated Pro2 SC10 and Trophy Rat are designed to improve crash survivability over stock A-arms.

RPM started by increasing the amount of material surrounding the hinge pins. They then ditched the offset button head screws that prevent the hinge pins from sliding out. The 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.

The support beams on RPM A-arms also gained some muscle. At their thickest, stock front A-arms are roughly 0.3" (7.62mm) thick. Rear A-arms are about 0.37" (9.4mm) at the thickest point, tapering down to 0.27" (6.86mm) at their thinnest — a loss of nearly 30% of their thickness at the outer hinge pins. RPM A-arms are a full 0.4" (10.16mm) thick over nearly their entire length, tapering only slightly at the hinge pins to match the maximum size allowable of the hinge pin bosses. The width of the A-arm support beams is beefier as well.

All RPM A-arms are molded from an engineering-grade nylon blend for performance you can trust.

RPM Front & Rear A-arms fit the following Team Associated vehicles: Pro2 SC10, Trophy Rat, ProSC10, Reflex DB10, RC10T5M & RC10SC5M running Associated #71015 A-arms.

• RPM A-arms are sold in pairs.
