XRAY 325220 Universal Drive Shaft 77mm for XB2 and XB4 rear suspension  [XR-325220]

Rear universal drive shaft for XB2/XB4

The XRAY 325220 universal drive shaft is an RC-scale rear driveline component designed for direct replacement of standard rear drive shafts on XB2 and XB4 platforms. Manufactured from Hudy spring steel and offered in a 77mm length, the part aims to provide a freer drivetrain feel with reduced binding during suspension travel.

In practical setup terms, the universal joint geometry permits more compliant suspension movement over uneven surfaces, which can help the chassis maintain traction on bumpy courses and astro tracks. The shaft's finish and design reduce dust accumulation around the joint area, lowering routine cleaning frequency for track sessions with loose grit or artificial turf.

Installation is straightforward for experienced technicians: the part uses the same mounting interfaces as the original rear shafts and fits the rear axle assemblies of XB2 and XB4 models. When tuning, consider ride height and camber settings first, then evaluate driveline response; a universal shaft typically alters transient behaviour compared with a rigid axle, so small adjustments to damping or anti-roll setup may be needed to restore a chosen handling balance.

For XB2 and XB4 users seeking a direct-replacement rear shaft with reduced drivetrain binding and lower maintenance on dusty tracks, this Hudy spring steel universal drive shaft provides a practical option to evaluate within race setup work.
