Eliminate Linkage Deflection for Razor-Sharp 6-Speed Shift Feel
Remove vague gate feedback and rubbery shift motion in your 6-speed gearbox with the Kartboy 6-Speed Solid Shift Joint (KB-001-01005). Designed as a heavy-duty, direct replacement for the soft factory rubber-isolated u-joint at the transmission selector, this upgrade delivers immediate, mechanical shift engagement without binding or flex.

Engineered Bind-Free Design with Stainless Crush Tubes & Bronze Bushings
Unlike basic aftermarket joints that pinch or bind when fully torqued, Kartboy’s solid 6-speed joint features press-fit bronze bushings, stainless steel center cross tubes, and precision crush sleeves. This unique assembly allows you to properly torque mounting hardware while maintaining fluid, bind-free pivot rotation through every gear change.
