Wear Bushing support Ball Spline

The BERT Transmissions Wear Bushing Support Ball Spline (Model 3-20) is a precision-engineered aluminum support component designed for high-performance manual transmission builds. This wear bushing assembly supports ball spline geometry and is essential for maintaining proper shaft alignment and reducing lateral movement in performance-oriented transmission systems that demand reliability under load.

Fabricated from aluminum in natural finish, this component measures 3 x 1.6 x 5.1 inches and weighs just 0.2 lbs, making it lightweight without sacrificing structural integrity. The ball spline design allows for controlled axial and radial movement while the bushing wear surface manages friction and wear during transmission cycling. Builders working with BERT transmission systems recognize that precision support components like this directly influence shift quality, reduce play in the drivetrain, and extend the service life of internal spline interfaces under repeated engagement cycles.

This wear bushing support ball spline is specified for serious transmission builders and restorers working on performance manual transmissions where original equipment specifications or upgraded reliability is non-negotiable. Whether rebuilding a BERT transmission system or upgrading an existing assembly, having OEM-quality support components ensures consistent shift feel and durability. Each unit is sold individually, allowing builders to source exact-match replacement parts or complete full transmissions with confidence in component integrity.

BERT Transmissions components are recognized in the performance automotive community for precise manufacturing and compatibility with both stock rebuilds and upgraded transmission assemblies. The wear bushing support ball spline represents the kind of precision engineering that separates reliable transmissions from those prone to premature wear or shift inconsistency.
