I have yet to measure my Rubicon Express BB kitted 2 door, and I couldn't see a visual shift in the axle; but is 1/8" all we're generally talking about with such small lifts? Mine tracks straight and no other complaints thus far; and what's 1/8" among friends!

Cheers.

Also, 33 inch tires with the stock 3.21 gears??? Issue or not? (SORRY TO HIJACK!)
It's just a rumor and one probably started by a few dealers. Your dealer cannot void warranty work unless they can prove that the break you are trying to warranty was caused by your lift.

As far as 33's and 3.21's go, it'll be tollerable.... but just.

If you are manual. With my auto and 4.10's, I "lack" on the highway passing and going up hills. Besides that, all is well.

As far as pulling to one side goes, the axle shift should not make enough of a difference to cause this to happen. As far as bump steer goes, you would only get this if you installed a front track bar relocation bracket without a dropped pitman arm or vice versa - Installing a rear track bar relocation bracket would NOT fix bump steer due to the fact that your rear axle does not control steering. Honestly, the info you have been getting is only half accuate if not absolutely terrible and I would not advise you to trust any of it.



Yes, the shift in your axles would happen with any lift kit if you do not install an adjustable front track bar to recenter your axle or a rear relocation bracket to help recenter it. It's a simple matter of math and hardly what I would consider to be a "problem" on a budget boost.

In all honesty, you should not have any problems installing a simple budget boost. Trust me on this
Thanks I've been wondering while after I installed the 2.5" BB why when I hit bumps or go over railroad tracks the Jeep gets kind of all willy nilly on me .
I installed a front track bar relocation bracket when I did the lift. SO my options are to take it out or buy a drop pitman arm and the squirlyness should go away is that right?
