PRW Dodge Cummins high performance shaft rocker arm systems are the perfect upgrade to allow more power and run your motor more efficiently. Each rocker is made from alloy
steel substantially thicker than stock and our shaft system is made as a “drop in” assembly using the stock ratio. This upgraded rocker arm system comes complete with everything you need from ball adjusters and fasteners, along with silicon bronze bushings instead of the oem style needle bearings.
