2003 Ram 3500 6 speed
Location: Ohio
I have had the R2 125hp nozzles in my truck since December 2015 and they have performed phenomenally. I also have an S364/71/13 with HTT housing and T3 flange, AirDog 150, and a dual disc clutch on the truck too. The truck keeps really good temperatures; usually 650* on the highway and no more than about 1,100* with a hard pull with a load. Truck is 4x4 with 4.10 rear and gets 17mpg on a 270 mile trip from Ohio to Indiana. I haven't had a problem with them and would highly recommend.
