RPM Front 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. Starting 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. 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!
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).
