Not sure if a 3.42 rear end would work for you in your 2500 with the big 6.0 but with the difference I get with it in my truck compared to even a 3.73 is quite a difference.. I bet I get 2 miles per gallon more with the 3.42 and maybe even more than that if I had a 3.73..
Just curious if this rear end ratio would work with the combination you have with the horse power and weight ..
You,,or any one have any thought on this ,, GP
