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. We then evaluate 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, weve added nearly 10% more material surrounding the pivot ball and, coupled with our stronger materials, virtually eliminates pivot ball breaks. Weve 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 our A-arms will be virtually non-existent.Tech Notes:
RPM Upper A-arms for the Traxxas Unlimited Desert Racer are sold in pairs and replace stock Traxxas #8531.
