Details:

Lock Down Driveline Movement for Crisp, Direct Gear Selection
Eliminate sloppy drivetrain flex and restore mechanical shifting precision with the Kartboy Transmission Crossmember Bushings (KB-025-Trans). Over time, soft OEM rubber bushings installed between the transmission cradle and chassis wear out and sag, causing the entire transmission to pitch and twist under load. This 4-piece polyurethane upgrade firms up the crossmember for immediate driver feedback.

Heavy-Duty Polyurethane Construction
Molded from high-durometer polyurethane, these direct-replacement bushings sandwich between the transmission's lateral and horizontal support crossmembers. By removing unwanted drivetrain rotation during hard acceleration, aggressive downshifts, and high-performance cornering, engine energy is delivered straight to the wheels rather than wasted in chassis flex.
