You're tired of breaking stock rear A-arms, right? It usually happens when you're at your favorite bash spot and there isn't a hobby store within 50 miles too. That's why we came up with our rear A-arms for the ARRMA 1:10 scale line of vehicles. Our A-arms are stronger than stock and much beefier to help survive those out of control moments. In addition, we've dramatically reduced the amount of slop in the rear suspension system. This reduction in slop improves the camber and toe angles, making them more consistent and makes your vehicle easier and more predictable to drive. Each package comes complete with both rear A-arms. RPM A-arms are stock replacement parts and are manufactured from our incredibly tough blend of engineering grade nylons for A-arms that will survive out there where everything else would fail! Tech Notes: RPM Rear A-arms replace the rear A-arms from AARMA #330225. These arms work with most variations of the Granite, Vorteks, Raider XL, Fury and Mojave, including BLS, BLX and Mega versions.
