Flywheel Shim New Chevy 7 Hole

The Flywheel Shim New Chevy 7 Hole by BERT Transmissions is a precision aluminum spacer engineered to fine-tune engine-to-transmission alignment on late-model small block Chevy and V6 platforms. As an experienced mechanic knows, even minor discrepancies in flywheel runout or crank spacings can cause vibration, premature bearing wear, and drivetrain harmonics issues. This shim corrects those tolerances without requiring expensive machine work or component replacement.

Machined from high-grade aluminum and precisely milled to 0.038 inches thick, the Flywheel Shim New Chevy 7 Hole provides repeatable dimensional control during transmission swap assembly or rebuild. The 7-hole pattern matches late small block Chevy and V6 bell housing configurations, ensuring proper bolt alignment with minimal risk of cross-threading or hole damage. At just 0.03 lbs and measuring 3.9 x 0.05 x 3.9 inches, this shim integrates seamlessly into existing drivetrain stacks without requiring adapter plates or secondary spacers. Natural finish aluminum resists corrosion in engine bays while maintaining dimensional stability across thermal cycles.

Transmission builders, hot rod fabricators, and rebuild specialists rely on flywheel shims to achieve OEM-spec crankshaft-to-input-shaft concentricity on budget builds or performance restorations. Whether you're installing a modern overdrive box on a classic small block or diagnosing vibration after a turbo conversion, having the correct thickness shim on hand prevents repeat teardowns and customer comebacks. Stock this item for any late Chevy V6 or small block project where precision alignment matters—from street machines to full restorations.
