This is a pair of RPM Front Upper A-Arms in Black for the Traxxas Unlimited Desert Racer. Have you managed to break an upper 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 Upper A-arms on your Unlimited Desert Racer for guaranteed 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. RPM then evaluates why the stock parts break and build our 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 has added nearly 10% more material surrounding the pivot ball and, coupled with their 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 RPM A-arms will be virtually non-existent.
