so i have a 2006 6-speed TJ with 3.07 gears and - knowing that my acceleration will suck - i ordered 33" GD Wrangler Duratracs for this summer.
right now, i have a 2" OME lift with the usual stuff (spring coils, shocks, TC drop, trackbar relocation) but i obviously need more lift for the tires. i don't want a body lift, so i thought about putting in 2" coil spacers for now. to compensate for the extra height, i'll order the 4" procomp MX6 adjustable shocks (i found the OME too soft anyway).
i was thinking this shouldn't be too much of an issue from a technical side. but now some jeep expert here in switzerland (where i live) told me that going up to 4" will require me to elongate the brake wires and readjust the power train and so and so forth.
so far, i've only had a bit of an issue getting in the reverse gear in my 6-speed manual after lifting to 2".
what do you guys think?
any advice or input is highly appreciated! thanks!
Your probably going to see issues with front and rear trackbar positions moving your axle sideways under the jeep.You might need adjustable trackbars to center the axle.I ran an OME lift with 1 1/4 spacers in the rear and 1 3/4 spacers up front for years.I had an adjustable front trackbar that I adjusted after adding the spacers.The rear moved a little but I just dealt with it.The rear trackbar relocation brackets are different heights for a 2.5 vs 4" lift.Also you might run into driveline vibs,as you will be like 4-4.5 inches of lift.Really should have a SYE/cv rear driveshaft.
With a 4" lift, you really only need a new front adjustable track bar, if you have the relocation bracket for the rear, you should be fine. I second getting a SYE/CV driveshaft, but try not to order it from quadratec-can be kind of expensive. I try and look around a lot to find a good deal. You shouldn't need brake lines unless you have upgraded to new control arms which would give you more flex off road.
The requirement (at least it is STRONGLY!!! recommended) for a SYE once you get to 4" of suspension lift has nothing to do with Death Wobble. The SYE allows a longer driveshaft to be installed which corrects (reduces) the steepened driveshaft angle caused by that tall of a suspension lift. That steepened angle causes severe drivetrain vibrations caused by the u-joints on the driveshaft. The longer driveshaft installed with the SYE kit is also a CV (constant velocity) style which helps manage the amount of angle seen by any of the CV driveshaft's 3 u-joints. The OE driveshaft only uses 2 u-joints. Not to mention the OE driveshaft starts getting too short at a 4" suspension lift height which can cause the driveshaft to pull off the t-case output shaft if the suspension gets totally flexed out on a tough trail.
You will also need adjustable length upper control arms to adjust the rear axle's pinion angle upward to match the requirements of a CV driveshaft.

I believe you can get a rear adjustable trackbar to use with an existing relocation bracket,so you wouldnt have to take it off.RE makes them.A couple things ive learned about rear relocation brackets,#1 the brackets are different heights between the 2.5" OME and a RE 3.5" superflex,sooo you wont be perfect with 4+ inches of lift and the OME relocation bracket.#2 the brackets are also different depending on if you use a SYE/cv setup vs a transfer case drop.Ones angled (SYE/CV),the others straight (transfer case drop)..Muy importante things to think about.....
wow, thanks for the warnings...!! guess i completely underestimated the scope of this. muy imortante things indeed!
so following jerry's argument (thanks for the explanation!!), i'm pretty much screwed unless i go for an SYE/CV shaft, right? any good places to get these? 4wd.com? i got a car mechanic who helps me with all my wrangler issues, but he's not that experienced with jeep parts...
or how else will i be able to fit my (already shipped) 33's, with fender flare removal/trimming not being a legal option here...?
dammit i'm a stupid kid for not thinking this over...
