Arrington ST-3A Camshafts and Push Rods
Call For Availability-Arrington introduces its new line of high performance camshafts for your 5.7L or 6.1L Dodge, Chrysler, or Jeep engine. This package includes a set of our ST3A camshafts and push rods. These HEMI cams are dyno proven to add 52 horsepower and 20 ft-lbs of torque to an otherwise stock engine, with basic tuning. 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. Now this process is being applied to 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 required in order to install these camshafts. Catastrophic engine failure may result if the stock valve springs are not upgraded.
