RPM Shock Shaft Guards are a simple design, replacing your stock shock spring cup with one that has a thin but tough shield rising up to the base of the shock body, completely blocking debris from striking the shock shaft. The back and sides are open, which prevents debris from building inside the guard as well. The kit comes with replacement oversized shock rod ends, improving durability and consistency on the shock pivot ball. Additionally, they redesigned the top of the rod end so it is square. That square end keys the shock shaft guard for directional control. The front shield of the guard covers over 100 degrees of frontal exposure. These guards are zero friction protection devices, meaning the guard never touches the working elements of the shock. Sold in sets of four they will fit the Slash 2wd and Slash 4×4 as well as other Traxxas vehickles. Available in Black, Blue and Dyeable White materials.
