Part #: 19049-1

The original Ultra-Gold Aluminum Rockers changed the way racing and high performance street engine builders approached valve train design. Now, COMP Cams is revolutionizing valve train performance again with the next generation of Ultra-Gold ARC Series Aluminum Rocker Arms, featuring an Arced, Recessed, Contoured design. Using cutting edge design Techniques and manufacturing processes, Ultra-Gold ARC Rockers increase engine power, enhance valve train stability and improve oiling. Ultra-Gold ARC Rockers feature a new extrusion based on improvements developed through FEA analysis, resulting in an even stronger, stiffer body without compromising mass. A new arced channel and contoured top, similar to a bridge design, give the Rockers the best strength-to-weight ratio possible. The body has additional CNC contouring to improve clearances for valve covers and springs.

Constructed in the USA after FEA analysis, the Ultra Gold ARC rocker withstands up to 700 lbs pressure while improving power and stability. This 19049 rocker features a 1.72 ratio for use with 7/16" stud Ford 289, 302 and 351 Windsor.
