Pics would be great here. You can run 33's on almost any amount of lift, now you can't flex them on 1" of lift etc lol. How is your spacing of the tire in the fender well, is there a fairly large gap there? Without pics it would be hard to say. Noramal lift for 33's = 4 inches, however with all the types of lifts out there you have to look closely at what you have. 2 inch lift and 2 inch body lift would cause you to need a smaller shock than just having a plain ole' 4 inch suspension lift etc, etc, etc.
looks good new shocks are not going to make it ride much better.... looks like a 2 inch spring lift and a 2 inch shackle lift.. I would take those shackles off and go back to a stock one
x 2 for me...
85 CJ7 Build in progress, 258 with T-5 and dana 300.
Fiberglass tub Raptor lined interior, rustoleum lined the underside. Modified family roll bar from fender mounted rollbar. Full tie ins to the frame soon to come.
Stock shackles for a CJ are 3" center of the bolt hole to center of the other bolt hole. You really don't want to go more than 1" longer due to all the steering issues that really long shackels introduce on a street driven rig.
Because shackles are only on one end of the spring, the lift they give you = 1/2 of the extra length beyond the 3" stock. ie a 4" shackle will give you 1/2" of lift, a 5" shackle will give you 1" of lift.
I would suggest you get 4" shackle. This will make sure they are long enough to work properly with your lift springs, help stableize your steering, and still give you 1/2" of lift.
You should clear the 33s just fine for street driving, just don't hit the curbs too fast ;-) you have not mentioned what kind of off road you want to do if any, so we can't really give you much advise of how much more spring lift you might need.
With a great Jeep comes an empty wallet.
I had to do the tranny drop on mine cause the CJ5 is so short.
I still needed to get extended brake lines anyway, mainly for the rear axle, the brake hose actually stopped the axle from dropping far enough.
I'm also running 33 X 12.5 on 10" rims on the CJ5 narrow track axles. If I had the wide track axle, it probably would not clear the fender lip. As it is on NT axles, they fit nice when flexing.
