Upgrade your classic Corvette’s clutch reliability with the Corvette Flywheel Shim .050 Inch (19631982). This precision spacer is a small part with a big impact, helping you achieve the exact flywheeltocrank spacing your build requires for smooth engagement and longterm drive feel.

• .050 inch precise thickness provides the exact spacing needed to set the proper flywheeltocrank clearance, promoting consistent clutch engagement and predictable behavior under load.
• Compensates wear and manufacturing tolerances across flywheel, crankshaft, and pressure plate components, preserving original feel even as parts age or are upgraded.
• Reduces engagement quirks by maintaining stable spacing, helping prevent clutch chatter, grab, or uneven takeup during shifts.
• Designed for classic Corvette powertrains specifically to fit 1963–1982 Corvette flywheel assemblies, simplifying restorations and performance upgrades without improvised shims.

This shim is ideal for enthusiasts restoring C2 and early C3 Corvettes, or anyone upgrading a clutch setup where precise spacing matters. By preserving accurate geometry between the flywheel and clutch components, it supports reliable pedal feel, smoother shifts, and longer clutch lifewithout the guesswork of bending or fabricating spacers.

How to use

1. Consult your service manual to confirm the target clearance for your build and verify that a.050 inch shim is appropriate.
2. With the drivetrain secured, remove the transmission to access the flywheel assembly.
3. Install the shim in the specified location to achieve the recommended spacing between the flywheel and crank/pressure plate assembly.
4. Reassemble, torque fasteners to the manufacturer’s specification, then test clutch operation during a careful breakin drive.
5. If you notice changes in engagement after breakin, recheck clearance and ensure there are no other contributing worn parts.

Compatibility and fit

Specifically engineered for 1963–1982 Corvette flywheel configurations, this shim integrates with original components and common clutch upgrades within that era, helping you maintain correct geometry across a range of rebuilds and performance tweaks.

Keep your classic Corvette’s clutch performance authentic and consistent with this precisely measured.050 inch flywheel shimthe small part that makes a big difference in how your car feels on the road.
