If you go 4" on a 2dr look forward to your caster being so far out of whack you'll barely be able to drive straight AND look forward to cutting part of your stock crossmember out for front driveshaft clearance.
At a minimum you'll need front lower adjustable control arms to get the caster close to being able to drive it on the road.
THEN your rear axle will be rotated so far back you may (or may not) need adjustable rear arms to keep springs from rubbing on trackbar
OH YEAH... You'll need an adjustable front trackbar to center front axle and rear bracket to center rear axle.... Both available from rock krawler
OR go to rivercityoffroad.com and talk to Marcus BEFORE you touch anything.... He WILL do you right
I have an 08 2dr and have made all the mistakes I've mentioned....
08 2 door (yes they made them) 3.5 RK lift, 35s lunchbox locked 30 front 44 LSD rear
