Output Bushing SG-1300 & SG-1400

The Output Bushing SG-1300 & SG-1400 is a critical wear component engineered for Bert Transmissions street and racing builds. This bushing supports the output shaft assembly, absorbing radial and thrust loads while maintaining tight tolerances during gear transitions. Whether you're running a stock rebuild, high-horsepower street cruiser, or dedicated drag setup, a worn output bushing introduces shaft deflection, noise, and accelerated seal failure—making replacement essential during any transmission overhaul or performance upgrade.

Designed to OEM specifications, the Output Bushing SG-1300 & SG-1400 features precision-molded bearing material that resists extrusion under load while maintaining shaft concentricity. The compact 3.6-inch outer diameter and 1.25-inch inner bore allow drop-in installation without modification to the transmission housing. Proper bushing preload and surface finish are critical; any erosion or excessive play introduces vibration that transmits through the driveline, reducing shift quality and accelerating differential wear. Quality replacement bushings like this one restore factory clearances and eliminate the slack that develops in aged transmissions.

Mechanics and transmission builders rely on this bushing for SG-1300 and SG-1400 applications, particularly when addressing output shaft runout or replacing seals that failed due to shaft movement. Installation requires careful alignment with the transmission center and verification of end-play before final assembly. Anyone rebuilding a Bert Transmissions unit, diagnosing driveline vibration, or servicing a high-mileage gearbox should verify bushing condition and replace it as part of preventive maintenance. This OEM-equivalent component ensures reliable performance and extends transmission lifespan under both street and competition duty.
