Factory spring-loaded lifters are a known failure point — they collapse, tick, and eat camshaft lobes over time. LS7 lifters feature improved internal valving for higher RPM capability and greater durability. Direct drop-in replacement — no machining or modification required. Prevents costly camshaft damage and associated labour before it starts. Ideal for AFM delete builds where DOD/AFM lifters are being removed entirely.
