RPM R/C Products - Front Upper A-Arms for the Traxxas Unlimited Desert Racer, Replaces TRA8531
10% more material surrounding the pivot ball, and coupled with RPM's stronger materials, virtually eliminates pivot ball breaks. RPM also increased the amount of material in both support arms leading to the pivot ball. The extra support material means breakage along any other area of these A-arms will be virtually non-existent.
