Would you like some more horsepower but don't want to do a cam swap? SLP's rocker arm package can take care of that for you. 4.8, 5.3 and 6.0 liter truck engines do not require SLP springs, retainers and keepers so the package below will have everything you need for the install -



Rocker-Arm Package (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 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

50185 SLP 1.85 Rocker Arm Package $559.99

Have a good day!
