Have you managed to break an A-arm on your Unlimited Desert Racer? If you have, you’ll find that replacing them is a serious chore. Save yourself some headaches and install a set of RPM Lower A-arms on your Unlimited Desert Racer for guaranteed unbreakable performance for the life of your truck.

RPM UDR Lower A-arms are redesigned from the ground up with one goal in mind – making them tougher than anything else available without breaking the bank. We start with some of the best engineering-grade materials, building a completely new, original, one-piece A-arm designed with the UDR’s needs in mind. We beefed up the support arms in the direction of suspension travel. We then changed the angle of the A-arm at the pivot ball to improve clearance at the axle carrier. We also noticed stock A-arms actually contact the steering bellcrank at full suspension compression (and the wheels turned). Not so with RPM A-arms! Extra clearance means less chance of a bottomed-out suspension breaking the bellcrank. Factor in numerous other improvements, including slop reduction, and you have the best lower A-arms possible for your UDR!

Tech Notes: RPM Lower A-arms for the Traxxas Unlimited Desert Racer are sold in pairs and replace stock Traxxas #8532 & #8533 (pivot balls not included).
