GM LS1/LS2/LS6 Rocker Arm Set 1.7 Ratio Adj.

The GM LS1/LS2/LS6 Rocker Arm Set 1.7 Ratio Adj. by Sharp Rockers is designed for serious LS engine builders and street performance enthusiasts who require precise valve actuation and increased lift over factory geometry. These adjustable rocker arms are a direct replacement for the OEM stamped steel units found in Chevrolet's LS platform engines, allowing for cam profile optimization and enhanced valvetrain performance.

The 1.7 rocker ratio effectively multiplies camshaft lift, resulting in greater valve opening and faster closing events compared to the stock 1.5:1 geometry. This adjustment enables aggressive cam profiles to achieve optimal airflow without excessive lobe lift, which can stress pushrods and lifters. The adjustable design allows for fine-tuning of rocker geometry and lash preload, essential for controlling valve float at high RPM.

This rocker arm set is compatible with LS1, LS2, and LS6 variants, making it ideal for a variety of applications, including fuel-injected crate engines and LSx swaps. The robust construction ensures durability under high-RPM operation and valvetrain impact loads, providing reliable power delivery and engine longevity.
