SLP Rocker-Arms, LS1/LS6/LS2 (1.85 Ratio).

SLP is proud to re-release our 1.85-ratio rocker arm package for GM "Gen III" engines which includes LS1, LS6, LS2 as well as 4.8, 5.3 and 6.0 liter truck engines. Designed as a true bolt-on replacement, these new rockers require NO valve cover or cylinder head modifications (please reference our instructions for proper installation). Our exclusive design is based off of the stock rocker providing an OEM quality steel construction and a roller bearing trunion which 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. This package includes 16 rocker arms, detailed instructions and all required installation hardware.
