Product Details

Starting with the arced channel and contoured top, these Ultra-Gold ARC Series rocker arms from COMP Cams are built for strength and weight savings. This design, informed by FEA analysis, creates a stiffer body without adding unnecessary mass, which is crucial for a stable valve train. They fit a wide range of Chevrolet Small Block V8 engines, from the 265 cubic inch up to 400 cubic inch, and use a 3/8" stud with a 1.5 ratio. You'll find these on everything from classic Camaros and Corvettes to C10 pickups and Impalas.

COMP Cams has updated the design with CNC contouring to ensure better clearance around valve covers and springs, a practical consideration for many engine builds. They also feature a unique spring oiler channel running through the body to help keep components lubricated. Instead of traditional retaining clips, these rockers use durable spiral lock clips, similar to those found in piston pins, for a more secure fit. The included locking nuts have also been revised to offer a larger surface area, helping to maintain valve lash and reduce wear over time.

Manufactured entirely in the USA, these rocker arms are designed to handle up to 700 lbs of open spring pressure, making them a solid option for performance street and racing applications. They come with a lifetime warranty, reflecting COMP Cams' confidence in their durability.
