COMP Cams Rocker Arm GM LS1LS2LS6 1.8

If you're looking to get a little more performance out of your GM LS engine, especially if you're working with cathedral port heads on an LS1, LS2, or LS6, these Ultra Pro Magnum rocker arms from COMP Cams are a solid option. They're designed to increase the rocker arm ratio and stiffness over stock components, which can help raise valve lift and improve airflow without needing to swap out your camshaft. This makes them a popular choice for builders who want a noticeable improvement with a straightforward upgrade.

These rockers are made from 8650 chromemoly steel and are coated in black oxide for durability. They're built to handle up to 850 lbs of spring pressure, so they're well-suited for many performance applications. The 1.8 ratio is a step up from the factory ratio, and they're designed as a single bolt-down rocker arm, fitting pedestal mount LS engines. They are a direct fit for a wide range of GM vehicles, including many Chevrolet Silverado and GMC Sierra trucks, as well as Cadillac Escalades and Chevrolet Camaros.
