Rear A-Arms Black for Associated Pro2 SC10 and Trophy Rat (RPM72172)

RPM Rear A-Arms in black for the Associated Pro2 SC10 and Trophy Rat are replacement rear suspension arms, sold as a two-arm set, built to replace worn stock pieces and provide stronger, crack-resistant performance where hinge pins and outer beams bear the brunt of impacts.

Crafted from an engineering-grade nylon blend, these A-arms are thicker than factory parts—about 0.4 inches (10.16 mm) across most of their length—and use inline screws instead of offset button-head screws to reduce crack-prone holes and keep hinge pins secure. This design yields a tougher, more durable arm that helps maintain smooth suspension movement on rough tracks for the Pro2 SC10 and Trophy Rat platforms.
