COMP Cams Rocker Arms GM LS3 1.8 Bolt D

This set includes eight COMP Cams Ultra Pro Magnum roller rocker arms, specifically designed for GM LS3 engines. These are a 1.8 ratio, pedestal mount style, meaning they bolt directly onto the LS3's factory pedestal stands without the need for separate stud and guide plates. Roller rockers like these help reduce friction in the valvetrain compared to stock, which can lead to improved performance and durability.

The Ultra Pro Magnum line is known for its well-built construction. They feature a strong steel body and a roller tip to minimize wear on the valve stem and guide. The 1.8 ratio is a common upgrade that increases valve lift slightly over stock, which can help your engine breathe a bit better, especially if you've made other modifications to the valvetrain or intake system. This set is designed to be a direct replacement for your factory LS3 rocker arms, making installation straightforward for someone familiar with LS engine builds.
