COMP Cams Rocker Arms GM LS3 1.8 Bolt D

Made from 8650 chromemoly steel with a black oxide coating, these Ultra Pro Magnum rocker arms are built to handle up to 850 lbs of spring pressure. This robust construction means they're well-suited for performance builds where valve spring forces are significantly higher than stock. The 1.8 ratio is a notable increase over the factory rockers, which allows for improved valve lift without needing to change your camshaft. This is a full set of 16 bolt-down rockers, designed specifically for pedestal mount LS3 engines, including the necessary bolts for installation.

These COMP Cams rockers are a popular choice for enthusiasts looking to get more performance out of their GM LS3, L76, or L99 engines. They fit a wide range of vehicles, including models like the Chevrolet Camaro, Cadillac CTS, and GMC Yukon. By increasing the rocker ratio, you're effectively getting more lift from your existing camshaft profile, which can lead to better cylinder filling and improved engine breathing. The solid construction ensures they can handle the increased stresses associated with higher lift and spring pressures, making them a reliable upgrade for both street and track applications.

When installing these rockers, remember they are designed for non-adjustable pedestal mount heads. Ensure you have the correct tools and follow the manufacturer's recommended installation procedures to get the most out of this upgrade. This set includes all 16 rocker arms and the required bolts, making it a comprehensive solution for upgrading your LS engine's valvetrain.
