TRAXXAS Slash 4x4 Spring Steel Cup Joint for Front CVD Swing Shaft by GPM SSLA1280FST/JT  [SSLA1280FST/JT]

Front CVD Cup Joint for Slash 4x4

This spring steel cup joint is an aftermarket replacement part intended for the front CVD swing shaft on TRAXXAS Slash 4x4 scale RC trucks, supplied by GPM as SSLA1280FST/JT. It is offered as a direct-fit hop-up for the specified Slash 4x4 front driveline components and is designed for hobbyists who need a durable cup joint option for routine replacement or incremental drivetrain upgrades.

The component uses spring steel for the mating cup geometry to resist deformation under repeated articulation and torque cycles characteristic of RC driving. In practice this part acts as a wear item in the front CVD assembly, replacing a worn or damaged cup joint to restore crisp engagement and reduce slop in the swing shaft connection.

Installation is straightforward for users familiar with CVD removal and reassembly: disassemble the front CVD swing shaft per your vehicle’s service routine, inspect associated bearings and retaining hardware, press the cup joint into the yoke as needed, and reassemble with correct retaining clips or fasteners. Because material and fit affect driveline feel, pairing this part with well-serviced bearings and properly tightened fasteners helps preserve handling predictability.

From a tuning perspective, this spring steel cup joint provides a balance between toughness and the minimally compliant interface needed at the front CVD; it is not a modification that alters gearing or suspension geometry but can influence perceived drivetrain backlash and feedback during aggressive maneuvers. Always verify compatibility with the exact Slash 4x4 front CVD swing shaft part numbers before installation.
