Part of my motivation for KYB is to 'take one for the team' by trying them out. Seems favorites have gone Bilstein/Rancho/Black Max.. and someone has a negative on each of them. Not a lot of feedback on the KYB. I'm no connoisseur on the comfort of a Jeep and expect the ride to improve over the Bilstein it came with.The compressed length of the KYB is right in line with an 11" rancho, but with about 1-1/4" less on the extended side. I would (and did) go with the rancho but if he's wanting to use the KYB specifically I doubt he'll miss the downtravel.
Edit: and even I have noticed that 'what's your favorite shock' is not a question that needs asking.
