LS1/LS6/LS2

SLP is proud to re-release our 1.85-ratio rocker arm package for GM 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.This package includes: 1.85 Ratio Rocker Arms 16 qty (50185)New bolts 16 qty Note 1 When using an aftermarket camshaft, please contact SLP for proper compatibility.Note LS1, LS6 and LS2 engines may require SLP springs, retainers and keepers reference chart below and part # 51185 rocker arm package when purchasing.SLP ROCKER-ARM COMPATIBILITY CHART (with stock camshafts)YEAR APPLICATION ENGINE Are SLP springs & retainers required?
