Competition Cams 73916 Titanium Retainer Valve Spring - Set of 16

COMP Cams Titanium Valve Spring Retainers 739-16 bring race-proven strength and weight savings to serious engine builds. Machined from aerospace-grade titanium, each retainer measures 1.625 inches in outside diameter for the outer spring, 1.180 inches in outside diameter for the middle spring and accepts an inner spring with a 0.635-inch inside diameter. The standard retainer style features a 10-degree lock angle and is engineered for triple-spring applications. Sold as a set of sixteen retainers, locks are not included—allowing you to select COMP Cams valve locks and optional lash caps that best suit your setup. By replacing heavier steel retainers, this titanium kit reduces reciprocating mass for sharper throttle response and enhanced stability at high RPM, making it the top choice for racers who demand uncompromising performance.
