Crower 74164F2 Features:

Crower 74164F2 stainless steel shaft-mounted rocker system for Brodix LS Series STS BR-7 BS-design-only heads and Mast 510-224J, 510-225J, 510204J, 510-270J, and 510-209J heads. Heavy-duty 5/8 in. shafts with a 1.550 in. arm length, .450 in. intake offset, and .050 in. exhaust offset for precise LS valvetrain geometry in matched applications. Engineered for extreme high-valve-lift setups from .800 in. to .850 in., helping support demanding racing combinations that require shaft-system rigidity and accurate rocker motion. Stainless steel construction maintains strength under sustained high temperatures and offers longer service life potential than aluminum rocker designs in severe-performance use.
