The COMP CAMS SB/BBC Pro Magnum Hyd. Lifter is a precision hydraulic flat tappet lifter designed for small block and big block Chevy V8 engines, as well as select GM V6 applications. This lifter is essential for builders and enthusiasts who seek reliable valve train performance without the complexity of solid lifter setups.
Hydraulic lifters automatically adjust for valve train clearance and wear, making them ideal for street engines, restorations, and performance builds where consistent valve timing is critical. The Pro Magnum hydraulic lifter features a 0.842-inch outer diameter optimized for flat tappet camshaft compatibility, delivering superior oil flow management through internal check valves and precision-calibrated piston assemblies.
Engine builders, classic car restorers, and street performance enthusiasts benefit most from this lifter's reliability and ease of installation. It is compatible with stock and aftermarket flat tappet camshafts designed for small block Chevy (262–400 cu. in.) and big block Chevy (396–454 cu. in.) V8s, as well as applicable GM V6 powerplants.
