COMP Cams Rocker Arm Ultra Gold Arc SBC

Starting with the arced channel and contoured top design, these Ultra-Gold ARC rocker arms from COMP Cams are built for strength and weight savings. This unique design, similar to a bridge, is a result of FEA analysis, creating a stiffer body without adding unnecessary mass. They are manufactured entirely in the USA and feature a spring oiler channel through the body to improve lubrication, which is crucial for valve train longevity. The body also has additional CNC contouring to help with clearances for valve covers and springs, a practical consideration for many builds. These rockers are designed to handle up to 700 lbs of open spring pressure, making them a solid option for many performance applications across a range of Chevrolet V6 and Small Block Chevy engines.

The Ultra-Gold ARC series replaces traditional trunnion retaining clips with durable spiral lock clips, similar to those used for piston pins, for increased reliability. Stress-relieving radii are added to key areas like the body, trunnion, and pushrod seat insert to further enhance durability. Even the included locking nuts have been revised to offer a larger surface area, helping to maintain lash and reduce wear over time. This particular part, number 19002-1, is for Chevrolet V6 (200-262 c.i.d.) and Small Block V8 (265-400 c.i.d.) engines using a 3/8" stud and features a 1.6 ratio. They are designed to improve engine power and valve train stability while enhancing oiling.
