COMP Cams Rocker Arms Ultra Gold Arc Pon

What you get in this box are 16 COMP Cams Ultra-Gold ARC Series aluminum rocker arms, designed specifically for Pontiac V8 engines ranging from 265 to 455 cubic inches. These aren't just any rockers; they represent the next generation of valve train design, building on the legacy of the original Ultra-Gold rockers. They're built to enhance engine power, improve valve train stability, and ensure better oiling, all while being manufactured right here in the USA.

The ARC Series name comes from the unique arced channel and contoured top, which, combined with a new extrusion developed through FEA analysis, creates an incredibly strong and stiff body without adding unnecessary weight. This design also features additional CNC contouring to give you better clearance for valve covers and springs, which can be a real lifesaver during installation. Instead of traditional retaining clips, these rockers use durable spiral lock clips, similar to those used for piston pins, for a more secure fit. COMP Cams has even updated the locking nuts to increase surface area, helping to maintain lash and reduce wear over time. These rockers are built to handle up to 700 lbs of open spring pressure, making them a solid choice for performance builds.

These rocker arms are designed to fit a wide range of classic GM vehicles, including models like the Pontiac Firebird, GTO, and Grand Prix, as well as Buick models such as the Century and Regal. They feature a 1.5 ratio and are intended for use with 7/16" studs. COMP Cams backs these with a lifetime warranty, so you can install them with confidence knowing they're built to last.
