COMP Cams Rocker Arms Ult Gold Arc Pont

If you're building or rebuilding a Pontiac V8 engine, these COMP Cams Ultra-Gold ARC Series rocker arms are a solid choice for enhancing your valve train performance. Designed for Pontiac V8s from 265 to 455 cubic inches that use a 7/16" stud, these rockers are manufactured entirely in the USA. They are engineered to handle up to 700 lbs of open spring pressure, making them suitable for many high-performance street and racing applications. You'll find them fitted on a wide range of vehicles, including models like the Pontiac Firebird, GTO, Grand Prix, and Buick Regal from various years.

What sets these Ultra-Gold ARC rockers apart is their advanced design, developed using FEA analysis. This process resulted in an even stronger and stiffer body without adding unnecessary weight. The unique arced channel and contoured top, resembling a bridge structure, contribute to an exceptional strength-to-weight ratio. COMP Cams also incorporated additional CNC contouring to improve clearances, which is especially helpful when working with tighter valve covers or specific spring setups. For improved lubrication, a spring oiler channel runs through the body of each rocker arm. The retaining clips have been upgraded to a more durable spiral lock type, and stress-relieving radii have been added to critical areas like the body, trunnion, and pushrod seat insert. Even the included locking nuts have been revised to offer a larger surface area, helping to maintain valve lash more consistently and reduce wear over time.

This set includes 16 rocker arms with a 1.65 ratio, and they come with a lifetime warranty, reflecting COMP Cams' confidence in their durability. When installing, always refer to the manufacturer's instructions to ensure proper setup and to take full advantage of the design improvements.
