GM LS S/S Roller Rocker Arms - 1.7 Ratio

The GM LS S/S Roller Rocker Arms with a 1.7 ratio are designed for high-performance LS engine builds, suitable for enthusiasts and professionals alike. These rocker arms enhance valve lift and improve engine efficiency, making them ideal for both naturally aspirated and forced-induction applications.

Constructed from polished stainless steel, these rocker arms resist corrosion and maintain a refined appearance in visible engine bays. The full roller design minimizes friction at the valve interface, leading to lower parasitic losses and more consistent valve timing across the RPM range. The 8mm pedestal mount ensures compatibility with OEM LS-series engine configurations.

These rocker arms are particularly beneficial for those building or rebuilding LS engines with aggressive cam profiles or elevated boost levels. Their durable construction and precise valve actuation make them a reliable choice for high-performance applications.
