YIUIY New GM LS7 Lifters & Guide Trays For Chevy GMC LS/LQ 4.8 5.3L 5.7L 6.0L 6.2L

This is a complete set of hydraulic roller lifters and guide trays designed as a performance replacement for stock components. The set includes 16 lifters and 4 guide trays, manufactured from high-quality durable materials for long wear and maintenance-free performance. These lifters feature a large base design for durability in high-performance applications and are engineered to perform at higher engine speeds. They adjust the valves for proper engine performance and can be used with an LS3 valley cover to eliminate Displacement on Demand (DOD) in newer model engines. Before installation, it is essential to soak the new lifters in oil first—do not install them dry. After installation, do not operate the diesel engine for at least 30 minutes to prevent valve-piston contact. Some noise during initial startup is normal. These lifters are compatible with a range of LS engines including LS1, LS2, LS3, LS6, and LS7, and fit V8 sizes such as 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L. They are designed for Chevrolet (1992-2014), GMC (1992-2013), Buick (1988-2008), Cadillac (2002-2006), Hummer (2003-2007), Oldsmobile (1986-1999), and Pontiac (1988-2006) models. Always verify vehicle compatibility before purchase.
