COMP Cams Rocker Arm Ultra Gold Arc LS3

Starting with a CNC-extruded body, these COMP Cams Ultra-Gold ARC Series rocker arms are built for strength and stiffness. This design is especially important when you're running higher-load valve springs, which are common in modified LS engines. The roller tip is a significant upgrade over the stock slider tip, reducing friction and wear, particularly with high-lift cams. You'll also find a larger-than-stock billet trunnion package that uses captured needle bearings to help prevent failures, a common weak point in other designs.

These are non-adjustable, bolt-down rockers, similar to OEM LS rockers, making them a straightforward installation for many applications. They fit a range of GM vehicles equipped with LS3, L99, L92, L76, and '07+ 6.0L engines, including models like the Chevrolet Camaro, Cadillac CTS, and GMC Yukon. The 1.72 ratio is designed to work with pedestal-mount cylinder heads, and COMP Cams also offers a 1.82 ratio if you're looking to increase valve lift further without a full cam swap. Each set includes all 16 rocker arms, bolts, and pedestal mounts.

It's worth noting that aftermarket valve covers, valve cover spacers, or valve cover clearancing might be necessary to accommodate these rockers. COMP Cams backs these Ultra-Gold ARC rocker bodies with a limited lifetime warranty against breakage, reflecting their well-built construction.
