COMP Cams Rocker Arm Ultra Gold Arc SBC

COMP Cams has been a go-to for performance engine builders for a long time, especially when it comes to valve train components. They've updated their popular Ultra-Gold rocker arms with the new ARC Series, which stands for Arced, Recessed, and Contoured. This design is all about making the rocker stronger and stiffer without adding weight, which helps improve overall engine power and valve train stability. They're made in the USA and feature an improved oiling channel to keep things well-lubricated.

These Ultra-Gold ARC rockers are designed to handle up to 700 lbs of open spring pressure, making them a solid choice for many performance street and racing applications. The body has been CNC contoured to help with clearance issues you might run into with valve covers or springs. They also use a durable spiral lock clip to retain the trunnion, which is a more robust solution than traditional clips. The included locking nuts have also been revised to help maintain valve lash more consistently.

This specific part, the 19004-1, is set up with a 1.5 ratio and is designed for Chevrolet V6 and Small Block V8 engines (265-400 cubic inches) that use a 7/16" stud. It fits a wide range of vehicles, including popular models like the Chevrolet Camaro, Corvette, and C10 pickups, as well as various Buick and Chevrolet cars from the 70s and 80s.
