ISB guy looking into a CR
I'm looking into getting a CR Cummins to upgrade from my ISB for more room in the cab and more base HP. I have a few questions about buying a common rail though like what should i look for in a CR and what should I beware of, also are there any years with factory recalls i should avoid? Thanks in advance.

Make sure it's at least a 04.5 HO. Those are the 325/600 motors. Will have a sticker on the side of the valve cover that says 325 on the HP rating. The 48RE transmission is a good auto. I've got 170,000 on mine and tow heavy regularly. There aren't many TSB's for the 04.5's. The only issue with the 04.5's is the lift pump. the 03-04's had the lift pump on the side of the fuel filter and had a tendency to fail. The dealership would replace it with a in fuel pump like what is on the 05's and above. The 05's originally came with plastic end caps on the intercooler and had a tendency to blow under high boost. Those were replaced with the original metal end caps. So check those things if looking at those years. I love mine. Get over 20 MPG on the highway and around 16-17 when towing. Comfortable ride. Good luck.

take it from me if your running big power go stick or full built auto the stock re48s good but gives up around 400 hp and 777 tq mine slips and misses the 3 to 4 shift and pops between 1st and 2nd at lower speeds over all newer the better there great trucks enjoy its a huge leap over the vp 44 trucks
