TRAXXAS Slash 4x4 Aftermarket Rear CVD Cup Joint SSLA1277R/JT for swing shaft by GPM  [SSLA1277R/JT]

Aftermarket Rear CVD Cup Joint for Slash 4x4

This spring steel cup joint is supplied as an aftermarket replacement for the rear CVD universal swing shaft found on 1/10 TRAXXAS Slash 4x4 models and carries the model number SSLA1277R/JT. It is intended to interface with the SSLA1277RST rear CVD assembly and act as a direct replacement for that specific rear universal swing shaft cup joint.

Material and role: specified as spring steel, the cup joint offers torsional resilience and wear resistance desirable in compact RC drivetrains. It transmits torque between the differential output and the rear driveshaft while accommodating small angular misalignment from suspension movement.

Installation and tuning notes: fitted into the rear CVD housing using the vehicle's original retention points and hardware, the joint should be checked for correct seating and smooth rotation through full suspension travel. Confirm there is no binding or excessive slop. Replacing a softer factory cup joint with a stiffer, more wear-resistant unit can change drivetrain characteristics and is commonly used for maintenance and incremental tuning.
