Feuling Motor Company 1206 Valve Locks - .050" Offset 10° Steel

The Feuling Motor Company 1206 valve locks are precision-engineered steel valve locks designed to raise valve spring retainer height by .050" without requiring cylinder head machining. These 5/16" steel locks feature a .050" offset at 10° angle, providing critical clearance for higher lift camshaft applications.

Key Features:

• 5/16" steel construction for durability and reliability
• .050" offset design with 10° angle raises valve spring retainer height
• Eliminates need for cylinder head spring seat machining
• Gains .050" installed height for increased valve guide and seal clearance
• Supports up to .574" lift cams on 1984-2004 Big Twin and 1986-2003 Sportster models
• Supports up to .700" lift cams on 2005-2013 Twin Cam models

These valve locks are essential when upgrading to larger lift camshafts that require additional valve guide machining for seal and retainer clearance. The offset design provides the necessary installed height to prevent interference while maintaining proper valve train geometry. Ideal for performance builds and high-lift camshaft installations on Harley-Davidson Big Twin and Sportster engines.
