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

XB2 and XB4 rear universal drive shaft overview

The XRAY 325220 universal drive shaft is a rear driveline component for RC cars, designed to directly replace the standard rear drive shafts on XB2 and XB4 platforms. Forged from Hudy spring steel and supplied in a 77mm length, it aims to provide a less binding drivetrain feel during suspension travel.

In real-world setups, the universal joint arrangement allows the suspension to articulate more freely over irregular terrain, which helps the chassis keep traction on bumpy tracks and turf. The shaft's finish and geometry also help limit dust ingress at the joint area, cutting down on cleaning intervals between sessions.

Installation is straightforward for anyone familiar with these models: it uses the same rear mounting interfaces as the original shafts and fits into XB2 and XB4 rear axle assemblies. For setup work, verify ride height and camber first, then judge drivetrain response; universal shafts often change transient wheel control, so small damping or anti-roll bar alterations may be necessary to regain your chosen handling balance.

For XB2 and XB4 owners looking for a direct-fit rear shaft that reduces drivetrain binding and trims maintenance on dusty circuits, this Hudy spring steel universal shaft is a sensible component to trial when refining race setups.
