Extension Bushing

The extension bushing (model SG-1356) is a critical wear component designed for BERT late-model transmissions, specifically engineered to support the tailshaft housing assembly. This bushing absorbs rotational loads and maintains precise alignment between the output shaft and housing, preventing excessive play that degrades shifting quality and accelerates internal wear. Whether you're rebuilding a high-performance manual or restoring a transmission to factory specifications, a quality extension bushing is essential for reliable operation and longevity.

This extension bushing functions as a radial bearing surface, reducing friction between rotating and stationary components while maintaining clearance tolerances critical to transmission efficiency. Compact at 2.5 x 1.25 x 3.9 inches and weighing just 0.08 lbs, the SG-1356 is precisely machined to fit the BERT tailshaft housing bore, ensuring OEM-level fitment without shimming or modifications. The bushing material is selected for durability under continuous rotational stress, resisting the heat and pressure generated during power transmission while maintaining dimensional stability over extended service intervals.

Technicians and builders working on BERT late-model transmission assemblies rely on this bushing during complete overhauls, upgrades, or routine maintenance when tailshaft wear is detected. Installation requires proper press-fitting into the housing bore—careless installation can damage the bushing or bore, so precision tools and technique are essential. This component is sold individually, allowing mechanics to replace only worn bushings or maintain stock for frequent rebuilds without purchasing complete assemblies.
