The Brian Tooley Racing Titanium Retainers (BTR-SR007-16) are designed to deliver maximum strength and minimum weight for LS and LT high-performance valvetrain setups. Manufactured from premium-grade titanium, these retainers are a direct-fit replacement for GM #10166344 and compatible with all LS and LT beehive-style valve springs. The reduced mass improves valvetrain stability, allowing engines to rev higher without valve float while reducing spring stress and wear. Ideal for naturally aspirated, boosted, or high-RPM builds, these retainers are compatible with OEM GM, LS6, BTR SP011, SK018, TSP .550", .585", .625", PAC 1218, PAC 1219, and Michigan Motorsports .600" beehive springs. Each set includes 16 retainers, offering professional-grade quality and performance trusted by top LS and LT builders.
