Arrington High Performance HEMI Camshafts 

Arrington's line of high performance camshafts for your 5.7L or 6.1L Dodge, Chrysler, or Jeep HEMI engine are dyno proven to increase a 5.7 motor to 334.4 horsepower and 343.9 ft-lbs of torque from an otherwise stock engine, with basic tuning. On larger 6.1 engines, power is bumped to 419.9 horsepower and 412.3 torque. Not compatible with VVT motors.

For nearly a decade, Arrington has designed HEMI camshafts using both engine and valvetrain simulation in order to build the best cams for professional race teams. We use the same process to design and evaluate camshafts for our Mopar street and race engines. When creating the SR-2B and ST-3A, Arrington used the same HEMI Virtual Valvetrain process and race proven technology that it puts into every race engine. No other camshaft on the market can match these new cams in terms of street-able power and their advanced development process.

NOTE: A valve spring upgrade is recommended for use with these camshafts.
