I had 66k miles on my 02 2500 cummins, last spring and decided it was time to change out the shocks, before towing the trailer for summertime. I went round and round on what to buy - went with the Monroe Gas Shocks. I am sure they are correct for my truck (8800lb GVWR) . . . but, wow, they are not as good as the old originals I took off my truck - just way bouncier and not what I thought they would be. Thinking that I will have to move up to the Bilstein . . .
