Fits the 6.7L Cummins in 2007-2010 Dodge full-size trucks and 2011-and-newer Ram 2500 / 3500 pickups. This is a direct bolt-in upgrade over the factory unit — same mount, same pulley position, no bracket modification.
Diesel engines spend most of their working life at low RPM, and that is exactly where a stock alternator runs out of headroom. This unit holds 200+ amps at engine idle and delivers a full 370+ amps at cruising speed, hot rated — enough for a lift pump, auxiliary lighting, a winch, a plow, a welder or a competition-grade stereo without watching your voltage sag at every stoplight.
Engine codes covered: 6.7L ISB
Vehicles: Dodge / Ram 2500 3500
Our 240-, 320- and 370-amp Dodge/Ram Truck offerings have been a huge success for our customers over the years that we felt it necessary to bring a Billet option over to the lineup. It has been requested for a long time and we've finally been able to make that wish happen!
This new Billet version of our tried and true 370-amp alternator upgrade has all the same reliable attributes as the Cast version does but brings a new level of cosmetic appeal to those that need the ultimate show with their go. As an introductory offering only in black anodizing, we'll be watching and listening to our customer base to see if we need to bring in the colors like our long-time running GM billet options.
Offering over 200 amps just at idle and 370+ at driving RPM's, the only thing left for us to do was crown it with a Billet case!
Installation notes:
Plug and play operation/fitment. Uses OEM style 2 pin ECU communicating regulator for no battery lights or codes.
Uses OEM serpentine belt in most applications where the belt/tensioner/idler pulleys are in good condition.
0-gauge power and ground wire from the alternator directly to the closest battery needing charged is recommended for best output performance and reliability.
