Rocker Arms - Pontiac V8 1.5 Ratio 7/16 Stud

The Rocker Arms – Pontiac V8 1.5 Ratio 7/16 Stud from CROWER represent a precision valve train upgrade for serious engine builders and street performance enthusiasts. These rocker arms are engineered to replace stock units on classic Pontiac V8 applications, delivering improved valvetrain geometry and reliability during high-RPM operation.

CROWER rocker arms feature a 1.5 mechanical advantage ratio, which multiplies camshaft lift and translates it to increased valve opening at the cylinder head. The 7/16-inch stud attachment design ensures secure mounting to factory or aftermarket cylinder head pedestals and accommodates both hydraulic and solid roller cam profiles. Precision-machined from hardened steel with roller-tip geometry, these arms reduce friction losses across the entire RPM band while maintaining valve train geometry tolerances that stock pieces cannot match.

Pontiac V8 owners upgrading from worn OEM rocker arms, or those transitioning to aftermarket cam packages, will experience noticeably improved valve train response and durability. The 1.5:1 ratio provides the ideal balance between aggressive valve lift and acceptable pushrod angles, critical for engines running elevated boost levels, nitrous systems, or high-lift cam profiles.
