TeraFlex 2.5" Budget Boost Installation Write-Up
I'm thinking about this kit, but does it create a need for wheel spacers to even out the center of gravity? Also, having never messed with anything like this, how would i know if i did have off center axles or other problems? I can identify the shocks and springs - probably anyway, but what else is there that I am working with when putting on a budget boost? And, (last one I promise), are there any advantages to say, a FT 3" lift vs. the budget boost type kits?
Thanks,
Derek

No, wheel spacers are not needed for any reason.
Unless you install a track bar relocation bracket in the rear and an adjustable front track bar up front, you WILL have axles that are off center - period.
Please read the write-up carefully and look at all the detailed photos. They should tell you everything you need.
Sure, a Budget Boost is dirt cheap but new 3" coils will perform much better on the trail and in many cases, offer a better ride on pavement as well.

Well, my Teraflex bb came in a day early so with limited time available I decided to tackle the front of my Jeep for a good nights work.
Everything went pretty smoothly although I would like to add a couple of points to WOL's excellent write up.
First of all, due to high demand teraflex has changed from the bumpstop extensions up front to adding bumpstops to the axle pad via the ol drill and tap method.
The next thing I would like to add is that the shocks are definately the second travel limiting factor after the sway bars. I learned this the hard way when after removing the nut on the upper shock mount the axle quickly dropped and I ended up with a very sore leg thanks to the brake rotor nailing my shin! So it is a good idea to support the axle with a jack while removing the shocks.
Took her out for a quick test drive and I will have to agree with Eddie that the ride and handling feels almost unchanged at least with the stock BFG MT's. I was very impressed. Hopefully I can get my tires on tomorrow or thursday we'll see if she still handles well.

Hey duffman, is there a chance you could take a pic of this and post it here so that I and others could see it?
Man, I'm sorry to hear you got hurt and hope you are okay. However, step #2 in my instructions clearly indicate that you should "Leave the floor jack under the front axle to help support it." Also, if you look at the photo in step #4, you can even see the floor jack just behind the shock being removed

I'll take some pictures today of the new bumpstops.
I really should have known better when removing the shock. I just did my brother's 2000 TJ about a month ago and followed your directions exactly on 4x4xplor.com and everything went smoothly. I was probably just so excited when doing my own lift that I didn't even think about it! I think it actually hurt my ego more than my leg

Edit: Here is a picture of the new Teraflex BB front bumpstop:

Couple of additional thoughts on the Teraflex BB after driving around on it for a couple of days:
Finished up the rear last Wednesday, the brake line extension brackets when installed properly had a little too much bend in them which caused my brake lines to be streched badly in ways they are not supposed to. The fix was easy however, I just grabbed a hold of them once they were bolted on and gave a good tug to pull them out a bit and give my brake lines some much needed slack at full droop. The rear shock extensions were also a little tricky to get lined up but it just took some extra time and patience to get through.
I do have some ESP issues that I didnt have before but my steering wheel is slightly off center. These issues only occurr on onramps with some sort of bank to them. I can still take normal turns pretty hard with no problems but the ESP causes me to enter the freeway like I'm driving Miss Daisy. I'll have to center my steering wheel when I get some time and see if its still a problem.
Otherwise the ride and handling aren't much changed at all from stock even with my 305/70-17 Maxxis Bighorns. I have to say I'm quite please with the way my ride handles and looks now. Hopefully I'll have some time soon to see how she does off road!
The only gripe I have so far is I don't think I'm a big fan of the new front bumpstops in the kit. I was very careful to make sure they were centered on the spring perch but they are so wide that I think they slightly rub the springs on one side. I do think an adj track bar would solve this problem though as my axle has shifted only a tad to the drivers side but it is enough to slightly pull the spring in that direction as well which leads to the rubbing of the bumpstop. Maybe I can order some extensions in place of the bumpstops in the kit...
