RPM is synonymous with strength and durability, plus we’re known for taking the extra steps to design unique parts worthy of your favorite ride. That’s why we’re releasing these front upper and lower 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 suspension system at the hinge pins. This reduction in slop improves the caster, camber and toe angles, making them more consistent and makes your vehicle easier and more predictable to drive. Each package comes with 2 upper A-arms and 2 lower A-arms, enough to complete the entire front end of your favorite ARRMA 1:10 scale vehicle. RPM A-arms are manufactured from our incredibly tough blend of engineering grade nylons for A-arms that will outlast virtually every other part on your car! Tech Notes: RPM Front A-arms replace the front A-arms from AARMA #330225. Caution: RPM Front Lower A-arms will not work with certain inner (bulkhead) hinge pins that require a separate hinge pin retaining screw. They will only work with threaded style hinge pins (ARRMA #330018). These arms work with most variations of the Granite, Vorteks, Raider XL, Fury and Mojave, including BLS, BLX and Mega versions.
