These are the RPM Blue Shock Shaft Guards for Traxxas X-Maxx. Each pack includes two shock shaft guards. Two packages will be needed to complete one vehicle.
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, which 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 design, replacing stock shock spring cups with ones that have mounting holes for a thin but tough shield that rises 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 degrees 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.
As an added bonus, 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 series shocks - 7761, 7761A, 7761G, 7761R, etc) only. They have not been tested nor guaranteed to fit any other shocks for the X-Maxx. RPM Shock Shaft Guards replace Traxxas #7764 (spring cups only).
