A search resulted in 21 pages of discussion but nothing definitive I could take away. Perhaps someone can offer some additional information for me... Looking to put new shocks on my 2500 Duramax 4x...
I installed the rancho 9000 adjustable shocks on our 2001 3500 dually and noticed a difference when towing the TT we bought for the trip to Alaska. I install the yellow and blue bilsteins 4600 on our 05 when almost new and feel they are very good. Just looked at the original shocks for the 05 in the bilstein boxes in my basement and thinking why did I keep them. I "think" all four would be the better idea.
