Pontiac S/S Roller R/A's - 1.65 Ratio 7/16 Stud

The Pontiac S/S Roller R/A's - 1.65 Ratio 7/16 Stud from PRW Industries represents a premium stainless steel rocker arm solution engineered for high-performance Pontiac V8 engines. This set of 16 full roller rocker arms is designed for builders and enthusiasts seeking reliable valve actuation with reduced friction and wear compared to traditional stamped steel alternatives. Built to withstand the demands of modified and stock engine applications, these roller rocker arms deliver consistent performance across a wide RPM range.

Featuring a 1.65 mechanical advantage ratio, the Pontiac roller rocker arms amplify valve lift while maintaining precise control over valve timing and duration. The full roller design minimizes friction at the pushrod and valve stem contact points, reducing parasitic losses and extending component lifespan. The 7/16-inch stud mount provides secure attachment to the cylinder head, while the stainless steel construction resists corrosion and thermal stress inherent to high-heat engine environments. The natural finish preserves the material's durability without compromising structural integrity or aesthetic appeal in modern engine bays.

These roller rocker arms are ideal for Pontiac V8 engine rebuilds, restorations, and performance upgrades where reliability and improved valve train efficiency are priorities. The complete set of 16 eliminates the need for mixed component sourcing, streamlining installation on dual-valve Pontiac V8 configurations. Proper installation requires precision torquing to specification and compatibility verification with existing pushrods and valve springs. Whether restoring a classic Pontiac muscle car or upgrading a street engine, these stainless steel roller rocker arms provide measurable improvements in durability and valve train response.
