Nearly 25% lighter than stock Stronger material resists flexing and breaking Increased clearance in outer area of arms Overview RPM front A-arms for the Traxxas Slash, e-Rustler & e-Stampede are built to withstand some of the toughest abuse. Incredibly, we were able to shave some unwanted unsprung weight as well. RPM Front A-arms are nearly 25% lighter than stock versions of the same A-arms, yet the RPM versions are backed with our world-renowned breakage warranty. Additionally, we've increased clearance areas in the outer portion of the A-arms to allow increased droop travel when used in conjunction with RPM oversized bearing carriers (RPM #80372 & #80382). RPM front A-arms for the Traxxas Slash, e-Rustler & e-Stampede are sold in pairs and are available in either black or blue. These A-arms are molded with what is fast becoming an RPM trademark design of angled leading and trailing edges to reduce frontal edge mass and improve the a-arm's ability to ride up and over tall obstacles instead of slamming into them. RPM A-arms are extremely rigid for superior ride and stability over the roughest tracks and terrain.
