Nothing is more maddening than breaking parts when you’re out having fun. Even more frustrating is the chore of having to replace a lower A-arm on your Traxxas Unlimited Desert Racer. Save yourself some headaches and install a set of RPM Lower A-arms for guaranteed unbreakable performance from the toughest name in R/C, RPM!
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 TRA8532 & TRA8533 (pivot balls not included)
