SLP offers a 1.85 High-Ratio Shaft Mounted Rocker Arm Set for the 2010-2013 LS3 Camaro, 2008-2013 LS3 Corvette, 2007.5-2013 6.0/6.2 Chevrolet/GMC Truck /SUV's and 2009 LS3 Pontiac GXP. Designed as a true bolt-on replacement for the stock rocker arms, these easy-to-install rocker arms require no modifications.
Our exclusive 1.85 ratio design is based off the stock rocker arm design providing OEM-quality aluminum 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 HP over stock.
SLP's 1.85 L92/LS3 Rockers will provide L92/L76 or LS3 based vehicles with an additional 12 RWHP and 10 RW Ft-Lbs over the stock GM 1.7 L92/LS3 Rocker Arms.
Note: All 1.85 Ratio Rocker Arms are designed for non-DOD engines only.
