I bought this for my 2007.5 dodge ram Cummins 6.7. It was a direct fit. It arrived in 2 days with standard shipping. I would definitely recommend this part for anyone needing a replacement radiator for their Cummins diesel.

Exact fit and easy to install
November 3, 2018
Through an online search, I found 1A AUTO and very quickly found the radiator I was looking for. It was so easy to find that I was skeptical and continued my search. after a while I came back to this site and purchased the radiator. The price was good and it was shipped very quickly. When it arrived, there was some very slight damage on the box and I was concerned about the integrity of the unit so I contacted 1A AUTO. They were immediate to respond to my contact, My radiator was reasonably easy to remove and replace with only a handful of bolts and a few hose clamps. It did not come with new bolts, but the ones I removed were still in good condition so I reused them, My experience was a positive one and because of that, for future automotive needs I will start my search at 1A AUTO
