LS7 Shaft Rocker Arm Kit 1.80/1.80 Ratio

The T&D Machine 2008-180/180 is a premium full roller shaft mount rocker arm kit designed for GM LS7-series engines. These rocker arms feature a 1.80 intake and 1.80 exhaust ratio, engineered to provide increased valve train stability and reduced friction for high-performance LS engine builds.

This kit replaces the factory pedestal-mount setup with a rigid shaft-mount architecture, which prevents rocker arm deflection at high RPM and aggressive cam profiles. The components are machined for strength and reliability in demanding racing or street-performance applications.

Designed for precision, this kit requires verification of geometry and pushrod length during installation to ensure proper valve train alignment. It is recommended for experienced engine builders.

Compatible specifically with GM LS7-series engines featuring stock or aftermarket LS7-style cylinder heads. It will not fit cathedral-port or other LS head variations.
