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* (LQ4 OR LQ9) 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).
