SB/BBC Pro Magnum Hyd. Lifters

The SB/BBC Pro Magnum Hyd. Lifters from COMP CAMS are precision hydraulic roller lifters designed for serious small-block and big-block Chevrolet engine builders. These lifters provide reliable valve actuation without the complexity of traditional solid lifters, making them suitable for both high-performance and street engine builds.

Engineered to maintain consistent valve timing and lift, these hydraulic lifters eliminate the need for constant valve lash adjustment. The Pro Magnum design features a hardened steel body and precision-engineered hydraulic plungers that automatically compensate for minor clearance variations as the engine operates. This self-adjusting capability ensures that valve lash remains consistent across temperature and load cycles, enhancing longevity and performance.

Ideal for builders transitioning from worn solid lifter setups, these lifters significantly reduce valve train noise and shock, protecting critical components from accelerated wear. Their compact footprint allows compatibility with various stock and aftermarket cylinder head designs, making them a versatile choice for engine builders.
