SLP's 1.85 RATIO ALUMINUM ROCKER ARM PACKAGE is designed as a true bolt-on replacement for LS3 engines. These rockers require NO valve cover or cylinder head modifications. OEM-quality aluminum construction and a roller bearing trunnion results in a 10% increase in valve lift over the stock 1.7 ratio rocker arms and gains of up to 12 horsepower over stock. Retainers, keepers and SLP high-lift valve springs are included to prevent coil bind. Includes all necessary installation hardware and detailed instructions.
