LS6 5.7L Hydraulic Roller Camshaft

The GM Genuine Parts 12565308 is an LS6 camshaft, straight from General Motors engineers, designed for 5.7L and 6.0L engine rebuilds. It offers a factory LS performance cam with excellent drive-ability, a stock sound, and a broad torque curve, making it suitable for street use. This hydraulic roller camshaft features a 204/218 duration at 0.050" lift and 0.551"/0.547" valve lift with a 1.7 rocker arm ratio. The lobe separation angle is 117.5 degrees. This camshaft was originally released in the 2002 Corvette Z06 and produced 405 horsepower. For optimal performance and longevity, a valve spring upgrade to the LS6/LS9 valve spring kit (part number 12499224) is required. For vehicles equipped with an automatic transmission, a 2500-RPM stall torque converter is recommended. This genuine GM part is designed, engineered, and tested to rigorous standards. It is compatible with 2001-2005 GM vehicles, specifically noted for the Corvette (including Z06 and 50th Anniversary trims) and Cadillac CTS-V models with the 5.7L V8 engine.
