I fitted mine and used them off roading, the spends went down hill a lot since then and now i am up to 4.5"
(stop modding the WJ)
All is good with a 2" puck lift and fit to the top no matter what the instructions say front and back, its seen as a levelling kit for the weekend gypsys among you, if ya fit WJ diseasal springs will almost give ya 3" as they run a tougher spring.
My advice do it, gives it a nicer stance.......then muds, snorkel, 4" long arm kit, spacers, flares, winch bumper, 6" lift aaaaaahhhhhhhhhhhhhh.
Sorry its how my head works
Guru me up please, way more info than Jay
