2.8D off pavement tech report
In short, Fox 2.5/remote out-of-the-box (at 1-3/4" front lift and +1" blocks on the rear) rode even more rigid than stock Z71. Overdamped rebound made a pretty awful ride, especially on highway expansion joints. A 1-hr highway drive rattled the air filter caps off my ARB dual stage compressor which was mounted under the bed. BUT... after having Accutune Offroad retune the shocks (including an even higher flow piston than Fox used off the shelf), it now rides great and IMHO should be the standard ride for all these Colorados. They said most of tuning is done on the fronts, to match what happens on the rears (but they probably fiddle with the stacks on the rear shocks too). I'm grateful to have somewhat blindly chosen Fox based on reputation, and then learned from Accutune that they're easy shocks to re-tune, so a good choice.
YMMV
