LS1 GOLD RACE ROCKER KIT 1.7 RATIO

Gold Race Extruded Aluminum Roller Rocker Arms for LS1/LS6

Crane Cams Gold-Race, full-roller aluminum rockers for the LS1/LS6 engine family add up to 20 horsepower over stock! These rockers were designed for quiet operation and do not trigger the stock GM "Knock Sensor", which retards spark advance and reduces power output! They feature the exclusive Crane "Quick-Lift" design, which moves the valve off its seat quicker, initiating flow into the combustion chamber earlier, thereby increasing port efficiency and horsepower output! They are available in a complete kit (rockers, rocker studs, pushrod guideplates and pushrods) or separately, and are an easy bolt-on. They also clear stock Chevy LS1/LS6 rocker covers. Stock 1.7:1 and optional 1.8:1 ratios available.
