Arrington High Performance HEMI Camshafts 


Arrington's line of high performance camshafts for your 5.7L or6.1L Dodge, Chrysler, or Jeep HEMI engine are dyno proven to add 52 horsepowerand 20 ft-lbs of torque to an otherwise stock engine, with basic tuning. Notcompatible with VVT motors.

For nearly a decade, Arrington has designed HEMI camshafts usingboth engine and valvetrain simulation in order to build the best cams forprofessional race teams. We use the same process to design and evaluatecamshafts for our Mopar street and race engines. When creating the SR-2B andST-3A, Arrington used the same HEMI Virtual Valvetrain process and race proventechnology that it puts into every race engine. No other camshaft on the marketcan 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.

I had this installed in my 06 Magnum SRT @ 136k miles. At the same time I had PNP heads installed with updated springs and retainers. The result was a HUGE bump in power and a nice aggressive lope. This is an amazing cam and as proven by all the comments at Spring Fest 11, it is very popular for it's lope.
