S&S Cycle 50-7123 Valve Spring Shim .025" x .765" x 1.500"

The S&S Cycle 50-7123 valve spring shim is a precision-machined component designed for late 1981-1984 Harley-Davidson Big Twin motorcycles. This shim measures .025" thick x .765" inside diameter x 1.500" outside diameter and is used to adjust valve spring installed height and restore proper valve spring tension.

Key Features:

• Precision dimensions: .025" thickness x .765" ID x 1.500" OD
• Engineered specifically for late 1981-1984 Big Twin applications
• Restores proper valve spring pressure during engine rebuilds
• Compensates for valve seat grinding and valve refacing operations
• Quality S&S Cycle construction for reliable performance
• Sold individually for custom stack configurations

Valve spring shims are essential when performing valve jobs or engine rebuilds to maintain correct valve spring tension. When valve seats are ground or valves are refaced, material loss causes the valve spring installed height to increase, reducing spring pressure. Installing the appropriate thickness shim(s) under the valve spring restores the proper installed height and spring tension for optimal valve train performance.
