Why Upgrade to LS7 Lifters?

• 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.
