This spring steel cup joint is supplied as an aftermarket replacement for the rear CVD universal swing shaft on 1/10 TRAXXAS Slash 4x4 platforms and is designated SSLA1277R/JT. It is engineered to interface with the SSLA1277RST rear CVD assembly and functions as a direct-replacement cup joint for that specific rear universal swing shaft.
Material and role: manufactured from spring steel to provide a balance of torsional springback and surface durability, the cup joint is suitable where repeated torque loads and occasional impacts occur in compact RC drivetrains. The component transfers torque from the differential output to the rear driveshaft while permitting limited angular misalignment introduced by suspension articulation.
Installation and tuning notes: intended to be seated into the existing rear CVD housing using the original retention points and hardware; ensure precise seating and unobstructed rotation through full suspension travel to avoid binding or excessive play. Substituting a stiffer or higher wear-resistant cup joint is a standard tuning step that can modify drivetrain responsiveness under load.
