The COMP Cams 0.060" valve spring shim with a 1.250" outside diameter and 0.814" inside diameter equalizes installed spring heights for accurate valvetrain setup where thicker shims are required. Constructed from high-quality shim stock and heat-treated to tolerate radical cam lobe profiles, it preserves consistent spring seat height under aggressive cam timing. Available singly or in kits for full-valvetrain adjustments.
