Slash 4x4 Front CVD Spring Steel Cup Joint - SSLA1280FST/JT by GPM  [SSLA1280FST/JT]

Durable Front CVD Cup Joint for Slash 4x4

This spring steel cup joint is an aftermarket replacement designed for the front CVD swing shaft on TRAXXAS Slash 4x4 scale RC trucks, supplied as SSLA1280FST/JT. It fits as a direct replacement for the front driveline cup geometry and is intended for hobbyists replacing a worn cup joint or upgrading routine wear components.

The part uses spring steel in the mating cup profile to resist deformation under repeated articulation and torque cycles common in off-road use. In service this component replaces worn cups to restore tight engagement and reduce slack in the swing shaft connection, improving drivetrain feel.

Installation is straightforward for anyone familiar with CVD removal: strip the front CVD swing shaft following your vehicle maintenance steps, assess bearings and retaining hardware, press the cup into the yoke, and reassemble with the correct clips or fasteners. Pairing the cup with well-serviced bearings and proper fastener torque helps keep handling consistent.

From a tuning viewpoint, the spring steel cup joint offers toughness with minimal compliance at the front CVD; it does not alter gearing or suspension geometry but can reduce perceived backlash and improve feedback during aggressive driving.
