GM LS S/S Roller R/A's - 1.7 Ratio

The GM LS S/S Roller R/A's - 1.7 Ratio from PRW Industries is an essential upgrade for LS engine builders and performance mechanics focused on enhancing valvetrain stability and durability. These stainless steel roller rocker arms are specifically designed for high-revving applications where consistent valve timing geometry is crucial.

Constructed from premium stainless steel, these roller rocker arms feature hardened roller tips that significantly reduce friction compared to traditional designs. The 1.7 ratio multiplies camshaft lift, improving valve displacement and enhancing airflow, particularly in modified cylinder heads. This design ensures reliable operation under aggressive cam profiles and high RPMs.

These rocker arms are ideal for builders looking to exceed stock valvetrain geometry while maintaining reliability. Proper installation requires careful geometry verification and quality rocker studs, especially in high-performance applications.
