Universal Rear Shaft 77mm for XB2 and XB4 - XRAY 325220  [XR-325220]

Universal rear shaft tailored to XB2 and XB4

The XRAY 325220 universal drive shaft is an RC rear driveline part engineered for direct substitution of the stock rear shafts on XB2 and XB4 machines. Crafted from Hudy spring steel at a 77mm length, it is designed to reduce binding and allow a freer-rolling drivetrain.

Practically, the universal joint layout permits smoother suspension articulation over uneven ground, aiding traction retention on rough layouts and turf. The shaft's surface treatment and profile also limit dust accumulation at the joint area, cutting down on cleaning between runs on abrasive or artificial surfaces.

Fitment is straightforward for those familiar with these models: the shaft uses the same mounting interfaces as the original rear shafts and installs into the rear axle assemblies of XB2 and XB4 cars. For setup, start by confirming ride height and camber settings, then assess the driveline response; transient wheel control may shift compared with rigid setups, so minor damping or anti-roll bar changes could be beneficial.

For XB2 and XB4 operators after a drop-in rear shaft that decreases drivetrain tightness and lowers maintenance on dusty tracks, this Hudy spring steel universal shaft is worth evaluating in your setup routine.
