Ultra-Gold ARC Rockers, LS1/LS6/LS2, 4.8/5.3/6.0L, 1.72:1

Includes: Full Set of (16) 1.72 Ratio, Non-Adjustable Rockers with Bolts and Mounts. Non-adjustable, bolt-on, Ultra-Gold ARC Series Aluminum Rockers are more durable than both stock Rockers and other aftermarket aluminum Rocker designs. A CNC-extruded body provides increased strength and stiffness, which is especially important for higher-load springs. The Roller tip meanwhile is an upgrade over the stock slider, which is not meant for use with high-lift cams and springs that see increased load. What's more, a larger-than-stock billet trunnion package features captured needle bearings to help prevent failure. These pedestal-mount Rocker arms are offered in 1.72 and 1.82 ratios, with the 1.82 option providing a convenient way of increasing valve lift without having to undergo a full Cam swap. The Rockers include pedestal mounts and bolts, and just like the OEM LS Rockers, are a non-adjustable, bolt-down design. COMP Cams LS Non-Adjustable Ultra-Gold ARC Series Aluminum Rocker Arms also feature a limited lifetime warranty. Aftermarket valve covers, valve cover spacers, or valve cover clearancing may be required.
