The groundbreaking Ultra-Gold™ Aluminum Rockers redefined valve train design for racing and high-performance street engines. COMP Cams® continues to push the boundaries of valve train performance with the evolution of the Ultra-Gold™ ARC Series Aluminum Rocker Arms, featuring an innovative Arced, Recessed, Contoured design. Employing cutting-edge design techniques and advanced manufacturing processes, Ultra-Gold™ ARC Rockers not only increase engine power but also enhance valve train stability and improve oiling.
The new extrusion, shaped by improvements derived from FEA analysis, results in an even stronger, stiffer body without compromising mass. Featuring an arced channel and contoured top, reminiscent of 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 improved lubrication.
Gone are the traditional trunnion retaining clips, replaced by ultra-durable spiral lock-type clips, akin 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 # 19001 represents a rocker engineered for Chevy V6 200-262 & Small Block V8 265-400 cid (SBC) engines. With a 3/8" stud and a 1.5 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.
