These are the RPM Red Rear Suspension A-Arms for Traxxas electric Rustler and Stampede 2WD vehicles. These work on XL-5 brushed and VXL brushless versions. The arms work with all variations of the electric Stampede 2WD, including Skully, Craniac, and Bigfoot trucks.

RPM rear A-arms for the electric versions of the Traxxas Rustler & Stampede are stronger and more durable than stock versions, yet we’ve also managed to eliminate over 7 grams of weight per arm! That’s 14 grams of unsprung weight eliminated with a single pair of rear RPM A-arms! Coupled with a set of RPM front A-arms, the total weight loss exceeds 24 grams, or almost a full ounce! We accomplished this without creating any weak points nor are our A-arms any more flexible than the stock versions. Additionally, we’ve adjusted the shock mount locations slightly to allow more noticeable tuning adjustments when using the inner or outer shock mount holes (while the center hole remains in its stock location). While we were at it, we eliminated over 0.030” or 1/32” of slop from the inner arm mount and more than 0.010” or slightly less than 1/64” of slop at the outer hinge pin for an ultra-smooth, slop-free suspension system.

These are replacements for Traxxas 3655 and 3655X arms.
