I have a 2002 Chevrolet Silverado 2500HD 4x4 Crew Cab with 8.1L and Allison automatic transmission. I am pretty happy with the improvement these made. My stock bushings looked like they were in good shape even with 250k miles on them, but I figured it was worth a shot. These bushings seemed to tighten up the ride quite a bit, and eliminate the "frame beaming" complaint that a lot of people with these trucks notice.
Installation was quite a beast, but when you're wrestling leaf springs in and out you can expect that. Installation of the bushings was the simple part. Removing and reinstalling the leaf springs was tricky, and took the use of several unpleasant words to accomplish.
I installed the Prothane body mount bushings at the same time, and shortly after I did the front control arm bushings. The combination really tightened up the ride of my truck. It feels much more connected to the road, and handles much better. Initially the ride quality had more vibration, but after some miles that settled out quite a bit. It didn't return to the smooth ride of 250k mile bushings, but it settled down quite a bit. And no more "frame beaming!"
