Flywheel Shim New Chevy 7 Hole

The Flywheel Shim New Chevy 7 Hole by BERT Transmissions is a precision-engineered component designed to fine-tune crankshaft-to-flexplate alignment in Chevrolet engines. This shim is essential for mechanics and transmission builders who are rebuilding stock engines or assembling modified drivetrains, ensuring smooth engagement and reducing vibration.

Manufactured to exacting tolerances, this ultra-thin shim features a 7-hole pattern that matches factory Chevy crankshaft bolt configurations, allowing for easy drop-in installation. It compensates for variations between engine blocks, flywheels, and converter housings, which is crucial for achieving professional results in performance builds.

This shim is particularly beneficial for those working on Chevrolet vehicles, from street performance builds to drag racing applications, as it helps control end-play and axial clearance, minimizing parasitic drag and vibration that can shorten transmission fluid life and reduce efficiency.
