RPM Unlimited Desert Racer Upper Suspension Arm

RPM Unlimited Desert Racer Upper Suspension Arms guarantee unbreakable performance for the life of your truck. RPM UDR A-arms are tough for a number of reasons but it all starts with some of the best engineering grade nylons in the industry. They then evaluate why the stock parts break and build replacements to solve those problems. For example, customers have reported that the pivot balls tend to rip out of stock A-arms. To fix that issue, RPM added nearly 10% more material surrounding the pivot ball and, coupled with stronger materials, virtually eliminates pivot ball breaks. RPM has 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 the A-arms will be virtually non-existent.
