Supporting the unibody

Need jack stands that are tall enough to hold the unibody in the air such that the axles will actually droop.

Currently my ZJ is sitting on 5.5in lift and 33s. I cannot afford anymore lift or shop time, or their incompetence.

Anyone got a link to some tall jack stands for sale? Manufacturer or retail site?

Jack up the front or rear from the axle, place jack stands under unibody, remove tires, lower the Jeep on jack stands. You now have axle(s) drooping and unibody supported on jack stands.

Practically all 5 ton or 6 ton jackstands usually are sturdy and high enough for just about anything you need to do under your Jeep, and will let axles droop far enough. I've used ones like in the link below for many years now, under three different Jeeps.

If you need a few more inches, use a solid concrete cap or something of the sort. You can pick them up at Lowe's for like $2 and they are 8"X16" which should give you plenty of footprint to remain stable. I use these alot with my jack stands because I work in my gravel driveway.

I often use oak wood blocks on my jack stands if I want more height or I'm worried about harming the surface Im putting the stand under. Sometimes I worry about bending the uni-frame.

Some HF 6 ton jackstands I believe will suit you fine if doing Timo's suggestion(which I second). That's about the safest, easiest and more often the cheapest way. Only other ways I can think of would be a farm jack(if you have a hook point to use one) and jack stands with blocks of concrete(not very safe unless done exactly correct)
