When every gram counts in your high-RPM valvetrain, the PAC Racing Springs R509 Titanium Retainer provides the ultimate solution for weight reduction and increased durability. Engineered for 1.365-inch dual spring setups, these retainers are crafted from aerospace-grade titanium to withstand the extreme stresses of racing environments while minimizing reciprocating mass.

Advanced Engineering for High-RPM Stability

• Material Excellence: Lightweight titanium construction significantly reduces valvetrain mass, allowing for higher RPMs without valve float.
• Precision Fitment: Designed for 8-degree locks with specific 1.040" and 0.715" OD steps for a secure, perfect fit.
• Durability: Engineered to handle the high-heat and high-pressure demands of professional-grade racing engines.
• Optimized Geometry: The 500 Series design ensures maximum spring stability and consistent performance under load.

By reducing the weight at the top of the valve spring, these retainers allow your engine to rev faster and more reliably. They are the ideal choice for builders looking to maximize the potential of their performance valvetrain. Whether you are building a drag car, a circuit racer, or a high-output street machine, the R509 series offers the reliability you demand.
