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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLarge billet trunnion with captured needle bearings help prevent Rocker failure\u003c\/li\u003e\n\u003cli\u003eCNC-extruded body is much stiffer and stronger than competing aftermarket aluminum Rockers\u003c\/li\u003e\n\u003cli\u003eLimited Lifetime Warranty; So strong that we warranty the Rocker bodies against breakage for life\u003c\/li\u003e\n\u003cli\u003eOffered in 1.72 and 1.82 ratios (stock is 1.7); 1.82 ratio is easy way to increase valve lift\u003c\/li\u003e\n\u003cli\u003eDesigned for LS1, LS2, LS6 and LS-based truck Applications (4.8\/5.3\/6.0L)*\u003c\/li\u003e\n\u003cli\u003eRoller tip is an upgrade over stock slider tip and reduces friction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003e*Will not work with 2014+ L83 Direct Injection \/ VVT 5.3L or 2007+ 6.0L engines with rectangle port heads.\u003c\/span\u003e\u003c\/p\u003e","brand":"comp cams","offers":[{"title":"19024-16","offer_id":47803504066782,"sku":null,"price":670.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/2141\/7694\/files\/19025-16.jpg?v=1767726323","url":"https:\/\/harringtonspeformanceparts.com\/products\/ultra-gold-arc-rockers-ls1-ls6-ls2-4-8-5-3-6-0l-1-72-1","provider":"Harrington's Performace Parts","version":"1.0","type":"link"}
