Michigan Motorsports Titanium Retainers for LS/Gen V LT Beehive Valve Springs | MM-2011-16 | Fits 4.8L 5.3L 5.7L 6.0L 6.2L Engines | LS1 LS3 LS6 LQ4 LQ9 L83 L86 LT1 LT4 (Retainers + Locks)

The Michigan Motorsports Titanium Retainers (MM-2011-16) are engineered for maximum strength and minimal weight, providing superior valvetrain stability across all LS and LT applications from 4.8L to 6.2L. Machined from high-quality aerospace-grade titanium, these retainers drastically reduce valvetrain mass, allowing higher RPM potential, improved throttle response, and reduced spring fatigue. Designed to fit all LS and LT engines equipped with beehive-style valve springs—including GM LS1, LS2, LS3, LS6, LQ4, LQ9, L83, and L86—these retainers deliver professional-grade performance at a competitive price. Ideal for naturally aspirated, boosted, or nitrous builds, Michigan Motorsports titanium retainers provide precise valve control, longevity, and the peace of mind that comes from American-engineered performance parts.

• Lightweight Titanium Construction: Reduces valvetrain mass for faster RPM response, greater valve control, and extended spring life in high-performance LS and LT builds.
• High-Strength Aerospace Design: Titanium retainers resist flexing, distortion, and fatigue under extreme pressure—ideal for both street and competition-level applications.
• Designed for Beehive Valve Springs: Compatible with LS and LT beehive-style valve springs including OEM GM, LS6, BTR SP011, PAC 1218, PAC 1219, and other .560–.625” lift options.
• Fits 4.8L–6.2L LS & LT Engines: Engineered for LS1, LS2, LS3, LS6, LQ4, LQ9, L83, and L86 platforms, offering a direct fit that maintains OEM spring alignment and geometry.
• Sold as a Complete Set of 16: Includes sixteen precision-machined titanium retainers—ready to upgrade both cylinder heads for reduced mass and improved high-RPM control.
