PAC Racing Springs PAC-L8136-16 Mini 8-Degree Valve Locks for 5/16-Inch Valve Stems, Steel, Black Oxide, Set of 16

PAC Racing Springs PAC-L8136-16 Mini 8-Degree Valve Locks are designed for high-performance valvetrain applications using 5/16-inch valve stems. This set includes 16 steel valve locks with a black oxide finish, providing a durable and reliable connection between the valve stem and retainer. The Mini 8 design is suited for installations requiring a compact valve lock configuration while maintaining secure valve retention under demanding operating conditions.
The 8-degree angle helps provide proper alignment between compatible valve components, while the locks add 0.050 inch of installed height compared with the corresponding standard configuration. This makes the PAC-L8136-16 a practical choice for engine builders and technicians fine-tuning valvetrain geometry, installed height, and component compatibility. Verify the valve stem, retainer, and installed-height requirements before installation to ensure the correct fit and performance.
Constructed from steel and finished in black oxide, these PAC Racing Springs valve locks are built to withstand the repeated loads and operating temperatures associated with performance engines. The set-of-16 quantity supports a complete eight-cylinder application when one lock is used on each side of the valve retainer. Use these valve locks with compatible PAC Racing Springs components and follow the engine manufacturer's assembly and inspection procedures for proper installation.
