Long Pilot Bushing

The ALLSTAR PERFORMANCE Long Pilot Bushing (ALL 26112) is an extra-long bronze pilot bushing engineered for GM applications requiring precision clutch alignment and smooth engagement. This extended-length design addresses the specific geometry of certain General Motors drivetrain configurations where standard pilot bushings fall short of the required reach into the crankshaft pilot bore.

Bronze construction provides the self-lubricating properties essential for pilot bushing performance, reducing friction between the transmission's input shaft and the engine's crankshaft pilot hole. The extended length of this bushing ensures proper support across the full depth of deeper pilot bores found in specific GM engine blocks, preventing lateral movement and concentricity issues that can cause premature bearing wear and drivetrain vibration. At 4 inches in overall length, this bushing accommodates applications where longer reach is mandatory for correct alignment and function.

Technicians and engine builders working on GM muscle cars, performance engines, and rebuild projects rely on the correct pilot bushing length to ensure transmission input shaft concentricity and smooth clutch operation. Improper pilot bushing support—whether too short or too long—introduces runout that complicates clutch balance and can accelerate clutch wear. The ALLSTAR PERFORMANCE Long Pilot Bushing is specified for applications where the standard shorter geometry does not provide adequate support depth, making it essential for comprehensive drivetrain overhauls and rebuilds demanding OE-level precision alignment.

This single-unit pilot bushing is sold individually, allowing builders to source the exact component needed for their specific engine and transmission combination. Verify fitment against your engine block's pilot bore depth and your transmission input shaft geometry before installation to ensure optimal clutch engagement and reliability.
