PAC Racing Springs PAC-R408 1.050-Inch Titanium Valve Spring Retainer, 10-Degree

The PAC Racing Springs PAC-R408 valve spring retainer is designed for high-performance valvetrain applications requiring reliable spring control and precise component fitment. This titanium retainer is engineered for use with PAC Racing Springs 400 Series valve springs and supports a 10-degree valve lock configuration.

Featuring a stepped design with a 1.040-inch spring seat and 0.715-inch outer diameter, the PAC-R408 is intended for 1.050-inch dual valve spring applications. Its lightweight titanium construction helps reduce valvetrain mass while maintaining the strength and durability needed for demanding engine environments. The retainer is supplied individually for convenient replacement or custom valvetrain assembly.

Use the PAC Racing Springs PAC-R408 to help maintain proper spring alignment and consistent valve motion in performance engines. Confirm compatibility with the valve stem, locks, valve springs, and cylinder head configuration before installation. This retainer is not intended to be selected solely by spring diameter; the complete valvetrain combination should be verified for proper fit and operating clearance.
