Show original supplier description
The COMP Cams 19004-16 Ultra-Gold ARC Series Aluminum Rocker Arms represent a significant advancement in valve train technology for racing and high-performance street engines. Featuring an Arced, Recessed, Contoured (ARC) design, these Ultra-Gold rockers utilize a new extrusion developed through Finite Element Analysis (FEA). This results in a body that is both stronger and stiffer while maintaining a low mass, contributing to an optimal strength-to-weight ratio. Additional CNC contouring on the body ensures improved clearances for valve covers and springs. Each rocker arm includes a spring oiler channel through its body for superior lubrication. The trunnion retaining clips have been upgraded to durable spiral lock type clips, and stress-relieving radii have been incorporated into key stress areas. Even the included locking nuts have been revised to provide increased surface area for better lash maintenance and reduced wear. This specific set, part number 19004-16, includes 16 rocker arms designed for Chevrolet Small Block V8 engines ranging from 265-400 cid. They utilize a 7/16-inch stud and feature a 1.5 ratio. The aluminum construction and advanced design contribute to improved performance and longevity. The product is backed by a Lifetime Warranty and is suitable for use with up to 700 lbs of open spring pressure.
