| Rocker-Arm Package, LS1/LS6/LS2 w/SLP
Springs, Titanium Retainers, Keepers (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, springs, titanium retainers, keepers, detailed
instructions and all required installation hardware. Best of all, you'll save
$25 over the cost of purchasing the parts individually!
