The original Ultra-Gold™ Aluminum Rockers marked a significant shift in the approach to valve train design for racing and high-performance street engine builders. Today, COMP Cams® continues to redefine valve train performance with the latest generation of Ultra-Gold™ ARC Series Aluminum Rocker Arms, boasting an innovative Arced, Recessed, Contoured design. Utilizing cutting-edge design techniques and advanced manufacturing processes, Ultra-Gold™ ARC Rockers not only amplify engine power but also elevate valve train stability and enhance oiling.
The new extrusion, refined through FEA analysis, results in an even stronger, stiffer body without compromising mass. Featuring an arced channel and contoured top, resembling a bridge design, these rockers achieve the optimal strength-to-weight ratio. Further enhancing the design, additional CNC contouring improves clearances for valve covers and springs. Manufactured entirely in the U.S.A., all Ultra-Gold™ ARC Series Aluminum Rocker Arms incorporate a spring oiler channel through the body, ensuring superior lubrication.
Traditional trunnion retaining clips have been replaced by ultra-durable spiral lock-type clips, similar to those securing a piston pin. Stress-relieving radii have been strategically added to areas of the body, trunnion, and pushrod seat insert. Even the included locking nuts have undergone revision to increase surface area, ensuring better lash maintenance and eliminating wear concerns.
Part # 19021 represents a rocker engineered for Chevy Big Block V8 396-454 cid engines. With a 7/16" stud and a 1.7 ratio, these next-gen Ultra-Gold™ Rockers promise increased engine power, enhanced valve train stability, and improved oiling. Backed by a Lifetime Warranty, these rockers are built to last, suitable for use with up to 700 lbs of open spring pressure.
