What to do about sagging Jeep TJ springs?

It is a crap shoot. Pop over on Jeepsunlimited.com or rubiconownersforum.com. You will find many people have done OME without BL or Transfercase spacers. However, you'll find just as many that had vibe issues.

If you are buying a kit, they are selling you some extra things you may or may not need and discounting it in the hopes you won't need it and they will have still sold it to you for a profit. If you buy just the springs and shocks(of your choice), you can do fine. As was said, you can talk to 100 Jeepers and you will hear as many stories of vibes and no vibes. As much has to do with the loading of the vehicle, the age and use of the U-joints prior to lift, and driving style. Its a crap shoot. Good thing is the T-case drop kits can be had for cheap if needed. You can lower it a little at a time with hardened washers and new Grade 8 bolts for little money. This will give you the ability to tailor it to make the vibes(if present) go away and not drop it anymore than you have too.

Kits are nice cause you can get things a little cheaper. Problem is they often include some things you don't need. Either way the springs from OME and some good shocks will be the answer to your load carrying problems. Stay away from spacers. You need more spring to carry the load. The spacers will lift the frame off the axles but the spring will still compress fully under the load, because they have a lower rate than the OME's.

I feel like I should have stock in ARB with all the OME marketing I am doing, but the truth IMHO is they are the obvious choice for this application.

I had the same issue with my TJ/LJ. I fixed the problem by installing 5in RE springs in the back. Now with my rig fully loaded even with a small trailer attached I never hit the bumpstops.

Thats actually pretty good advice. I used that trick along with a set of OME HD springs on myTJ many years ago. Its interesting to note that OME does not refer to their kit as a lift but rather as a suspension system and in this case, its a good call. A lift in of itself will not cure your sagging problem as much as proper spring choice will.

I agree 100% on the proposed OME solution. You definitely may encounter vibrations without taking steps to correct the driveline. Due to a slightly shallower belly pan, 1997-2002 models are more prone to having vibrations than 2003-2006 models.
