Review on The Ultimate Suspension Upgrade: Skyjacker D25 Softride Coil Spring Set - Enhance Your Ride! by Donald Cox

Provides just over 2 inches of buoyancy, in some cases about 2 1/4 or so. Definitely a much better ride than the 2" spacers (which I replaced earlier). I've never owned a truck without coil spacers so I can't personally say if the ride is better than OE coils or not, but as I said, so much better than spacers. Definitely recommend and would buy again (if I ever get another one). cummins someday) 4 YEARS UPDATE: It's been 4 years since I installed them on my truck and I'm happy to report that they haven't done anything. but stick to both powder coat quality and ride height. They seem to have sagged a bit since I wrote my original review, but I'd say 1/8" MAYBE. Just enough for the truck to sit perfectly flush with the rear (factory rear lift blocks). They also seem faster / absorbing harder hits, even better with age All in all, still highly recommended!
