Red Rear A-Arms for Rustler/Stampede (2) (RPM80189)

Red RPM Rear A-Arms are a two-arm set of aftermarket rear suspension components for the electric, 2WD Traxxas Rustler and Stampede. They’re stronger and more durable than stock while shedding about 7 grams per arm—roughly 14 grams for the pair—reducing unsprung weight and sharpening suspension response.

These RPM rear A-arms fit the electric 2WD Rustler and Stampede and are designed to reduce play for a more precise ride. They eliminate more than 0.03 inches (0.8 mm) of slop from the inner arm mount and more than 0.010 inches from the outer hinge pin, delivering a smoother, tighter feel. The design also slightly adjusts shock mount locations to offer more tuning options when using inner or outer shock mounts, while the center hole remains in its stock location. This red variant is available, with other color options including black, green, and blue.
