High-Strength 10-Degree Valve Locks

Ensure your engine's valvetrain is secure with these PAC Racing Springs 5/16 valve locks. Featuring a 10-degree taper and a -.050 inch height reduction, these locks are designed for builders who need to adjust their installed height to achieve specific spring pressures. Built from premium steel and finished with a black oxide coating, these locks are engineered to withstand the extreme stresses of high-performance racing.

Why Choose These Valve Locks?

• Precision Engineering: Designed for 5/16 inch valve stems.
• Height Adjustment: -.050 inch height helps fine-tune spring seat pressure.
• 10-Degree Design: Offers increased surface area for better retainer engagement.
• Durable Finish: Black oxide provides excellent protection against wear.

The 10-degree lock angle is a staple in the performance industry, providing a secure connection between the valve and the retainer. By reducing the installed height by .050 inches, you can effectively increase the pressure on your valve springs, which is often necessary when running aggressive camshafts or high-RPM setups. These locks are a critical component for any serious engine build, ensuring that your valvetrain remains stable and reliable.
