Description

Ultra-Gold ARC Rocker w/ 1.72 Ratio for Pedestal Mount GM LS1 LS2 LS6 Includes: Single 1.72 Ratio Non-Adjustable Rocker Arm. 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. These Rockers 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. Large billet trunnion with captured needle bearings help prevent Rocker failure. CNC-extruded body is much stiffer and stronger than competing aftermarket aluminum Rockers. Limited Lifetime Warranty So strong that we warranty the Rocker bodies against breakage for life. Offered in 1.72 and 1.82 ratios (stock is 1.7) 1.82 ratio is easy way to increase valve lift. Designed for LS1 LS2 LS6 and LS-based truck Applications (4.8/5.3/6.0L). Roller tip is an upgrade over stock slider tip and reduces friction. Will not work with 2014+ L83 Direct Injection / VVT 5.3L or 2007+ 6.0L engines with rectangle port heads.
