PAC Racing Springs PAC-R432-16 400 Series Mini 8-Degree Titanium Valve Spring Retainers

PAC Racing Springs PAC-R432-16 valve spring retainers are designed for high-performance valvetrain applications that require dependable spring control and lightweight component construction. This set includes 16 titanium retainers engineered for use with dual valve springs and Mini 8-degree locks, providing a secure fit and consistent valve train operation in demanding racing and performance engine environments.
The 400 Series retainer design features stepped outside diameters compatible with specified inner and outer spring configurations. The 0.890-inch and 0.600-inch OD steps help support proper spring positioning while maintaining the compact profile required for specialized cylinder head and valvetrain setups. Titanium construction reduces reciprocating weight compared with conventional steel retainers, helping support improved valvetrain performance at elevated engine speeds.
Designed by PAC Racing Springs, the PAC-R432-16 set is intended for builders and engine professionals seeking reliable fitment, durable construction, and consistent performance. Verify spring, lock, valve stem, and cylinder head compatibility before installation to ensure the retainers are used within the requirements of the complete valvetrain assembly.
