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

Engineering Notes for Front CVD Cup

SSLA1280FST/JT is a spring steel cup joint intended as an aftermarket replacement for the front CVD swing shaft used on TRAXXAS Slash 4x4 platforms. The component is dimensioned for direct-fit installation into the yoke and is specified for repeated articulation and torque cycling common in off-road RC use.

The chosen spring steel geometry preserves the mating profile and resists plastic deformation under load, helping to maintain tight engagement in the swing shaft assembly. This part functions as a wear item within the front CVD system and should be installed alongside inspected bearings and retaining hardware for predictable performance.

Service procedure follows standard CVD disassembly: remove the front swing shaft, verify bearing condition, press the cup into the yoke to the correct seating, and secure with factory clips or fasteners. Correct installation and proper bearing maintenance are critical to avoid introducing additional driveline play.

From a setup perspective, the spring steel cup provides a low-compliance interface that does not alter suspension geometry or gear ratios but can reduce measured backlash and improve driver feedback during high-load maneuvers. Confirm compatibility with the exact Slash 4x4 front CVD part numbers prior to installation.
