I'm currently restoring my Jeep and I'm about to change the whole suspension system.
I'm planning on using 33x12" tires. Do you think 2.5" lift will be enough to go with? I'm afraid that 4"/4.5" will be too much and less stable on the road. Can I use longer shackles to gain some more height?
I also need your opinion on which brand to go with. Doing my homework, I found out that Old Man Emu is the best, but doesn't produce suspension systems for CJ's. There's a "CJ Spring Conversion Kit for use with YJ Springs", but don't know if that's trustworthy. My 2nd best option is Rubicon Express. Any other better brand?
Let me know what you think.
Your help me is greatly appreciated!!
I ran 32's on my '86 CJ-7 (you might want to include more info about your rig and intended usage, you'll get better answers) with a 2.5" Superlift and another 1/2" of lift from some Tomken shackles (most standard heavy duty replacement shackles are an inch longer than stock and will therefore give you a 1/2" of lift...I don't recommend much more than this in shackle lift) teamed with Rancho RS9000's for several years as a daily driver and moderate off-roader. For 33's, I'd add a 1" body lift. You'll also want to regear your axles to keep your performance up. Old Man Emu is arguably the best off the shelf lift for YJ's...adapting to a CJ is a fairly simple matter...there's nothing to trust or distrust about the conversion kit other than the price. The Rubicon Express Extreme Duty (*not* the standard duty) is probably the second best for YJ's and best for CJ's off the shelf and also offers a 4.5" version which Old Man Emu doesn't match. This is *also* a YJ kit...the CJ version just comes with the conversion parts. As far as the conversion, the rear is a direct bolt on. Up front you either use conversion shackle hangers and wider shackles or conversion shackles (this is the route RE uses...the top part of the shackle is the same size as stock to fit the stock shackle hanger, the bottom part is wider to fit the YJ springs). Beyond that, it's just new spring plates for the front with wider spaced holes.

33x12.5 with a 2.5in suspension and maybe a 1in body
Would 33x12.5 tires fit on a TJ with a 2.5 in skyjacker suspension lift work? If not what if I got a 1in body? Not doing any more than a 1 on the body seeing how its pretty ugly and I don't want that huge gap
Whoa a 5 year old thread revived in the wrong forum. I can tell you that on my CJ I ran 33" tires on a 2.5" lift with no problems.. I got some rubbing on my leaf springs (which you wouldn't have to worry about!), but it could be corrected probably with less backspacing on my wheel.
If you'd like an answer by someone who is running a TJ, you should post in the TJ section here...
