What is the benefit of the Arced, Recessed, Contoured (ARC) design?

The ARC design, along with FEA analysis, results in a stronger and stiffer rocker arm body without adding unnecessary weight. This improved strength-to-weight ratio can enhance valve train stability and potentially increase engine power.

What is required for installation with these rocker arms?

For proper installation and performance, these Ultra Gold ARC rocker arms require the use of screw-in studs and guide plates. The included locking nuts have also been revised for better lash maintenance.

What kind of warranty comes with these rocker arms?

COMP Cams offers a Lifetime Warranty on these Ultra Gold ARC Series Aluminum Rocker Arms, meaning you can expect them to last for the lifetime of your vehicle's use.

Product Details

Starting with an arced channel and contoured top, these Ultra Gold ARC Series rocker arms are built for strength and a good strength-to-weight ratio. COMP Cams used advanced computer analysis to refine the design, making the body even stiffer without adding extra weight. This updated design also includes CNC contouring to help with clearances around valve covers and springs, which can be a common issue on some builds. They are manufactured entirely in the U.S.A. and feature a spring oiler channel running through the body to improve lubrication to the valve train.

This set is designed for Ford Small Block V8 engines like the 289, 302, and 351 Windsor, using a 3/8" stud and featuring a 1.6 ratio. They are built to handle up to 700 lbs of open spring pressure, making them a solid option for performance street or racing applications. COMP Cams also updated the trunnion retaining clips to a more durable spiral lock type, similar to what's used for piston pins, and revised the locking nuts for better lash retention. You'll need to use screw-in studs and guide plates with these rockers.
