Rocks, dirt and debris striking your shock shafts lead to dents, dings and burrs, which, in turn, lead to torn shock seals. Torn shock seals means leaky shocks and poor shock performance. RPM Shock Shaft Guards shield the shock shaft from those deteriorating elements, prolonging the life of the shock shaft. Less damage improves the long-term performance of the suspension and in turn, prolongs the time between seal replacement and shock rebuilds.

RPM Shock Shaft Guards are a simple, yet effective design. We replace stock shock spring cups with versions that have mounting holes for a thin but tough guard. That guard acts as a shield, rising up to the base of the shock body. The guard completely blocks debris from striking the shock shaft. The back and sides are open, which prevents debris from building inside the guard as well.

The front shield of the guard covers over 100° of frontal exposure! That means rocks thrown from the front tires (or from that guy you’re trying to pass) won’t ever hit your shock shafts. RPM Shock Shaft Guards are zero friction protection devices, meaning our guards never touch the working elements of the shocks.

Additionally, we increased the length of the tubular spring support of the spring cup by nearly 2mm (5/64”). The added length helps prevent the spring from jumping off of the spring perch when the conditions are less than ideal.

RPM Shock Shaft Guards are sold in pairs and are stock replacement items.

Tech Notes: RPM Shock Shaft Guards fit stock Traxxas X-Maxx GTX shocks (Traxxas #7761, #7761A, #7761G & #7761R). Also fits XRT GTX shocks (#7861, #7861A, #7861G, #7861R & #7861T). They have not been tested nor guaranteed to fit any other shocks for either the X-Maxx or XRT. RPM Shock Shaft Guards replace Traxxas #7764 (spring cups only). Two packages will be needed to complete one vehicle.
