TRAXXAS Slash 4x4 Spring Steel Cup Joint SSLA1277R/JT rear CVD replacement by GPM  [SSLA1277R/JT]

Cup Joint for Rear CVD on Slash 4x4

This spring steel cup joint is provided as an aftermarket replacement for the rear CVD universal swing shaft used on 1/10 TRAXXAS Slash 4x4 vehicles and is identified as model SSLA1277R/JT. It is intended to interface directly with the SSLA1277RST rear CVD assembly as a serviceable cup joint for that rear universal swing shaft.

Material and role: constructed from spring steel to balance flexibility and wear resistance, the cup joint is suitable where torsional loads and occasional impacts occur in compact RC drivetrains. The component transmits drive torque between the diff output and the rear driveshaft while accommodating small misalignment from suspension travel.

Installation and tuning notes: designed to slot into the existing rear CVD housing and use the vehicle's original retention points and hardware. During installation confirm the joint seats correctly and rotates smoothly through full suspension articulation, and check for binding or excessive play. Swapping to a stiffer or harder-wearing cup joint can influence drivetrain response and is commonly used in tuning or maintenance routines.
