S&S Cycle 50-7122 Valve Spring Shim .765" x 1.50" x .015"

The S&S Cycle 50-7122 is a precision-engineered valve spring shim designed for performance engine builds on Harley-Davidson motorcycles. This shim is used to adjust valve spring installed height, ensuring proper valve train geometry and optimal spring pressure for high-performance applications.

Key Features:

• Precision dimensions: .765" inner diameter x 1.50" outer diameter x .015" thickness
• Black steel construction for durability and corrosion resistance
• Used to reduce valve spring installed height when needed
• Essential component for proper valve train setup with aftermarket cams
• Sold individually for precise engine building

Valve spring shims are critical components when building or rebuilding Harley-Davidson engines, particularly when installing performance camshafts. They allow builders to fine-tune the valve spring installed height to maintain proper valve train geometry and prevent valve float at high RPM. This shim is commonly placed under the bottom collar to reduce installed height when measurements exceed specifications.
