Change other parts with a 2" coil lift ?????

Guys, I'm seriously considering a 2" coil spacer lift. Will I need to change anything else like steering parts, etc in order to be reliable and proper? I know I'll need an alignment afterward.

caster may end up being low, so you may find adjustable lower control arms or cam bolts useful. you'll need bumpstop extensions (NOT longer jounce bumpers) and new shocks, which should come with the coil spacer lift. you'll also find the axles are slightly off-center, so you may want to address that...and there are a few ways to do that, but make sure to read this before buying a track bar.

here's a write-up:

^ your laundry list of potential problems is unsettling.

You'll need longer shocks and longer bumpstops, but if you dont wheel you can get away with doing absolutely nothing and just throwing the spacers on. Then as time/money permits, get shocks and other things that you feel you need. Bumpstop extensions are a no brainer, but again if you dont wheel, they wont make a lick of difference.

adjustable LCA's/track bar for a 2" BB?

caster may be an issue, depending on your tolerance for darty drive-ability. In addition to adjustable LCA's, I suggested cam bolts, which are a lower cost option and will work with a 2" lift...

Additionally, the axles will be off center. whether you use a 2" spring lift or a 2" BB, the result is the same. there are several ways to address that, if you even want to...adjustable track bars are one way to do that....I however did NOT suggest an adjustable track bar. I wouldn't buy one for a 2" BB, I'd bust out the welder & torch and modify the stock track bar....but then again, I wouldn't buy a 2" BB to begin with because there are way better options out there for similar money.

I've never seen a road that caused the rear axle to droop like that. What part of "if you dont wheel" wasnt clear? I dont think its a good idea to run around too long without the correct shocks, but you're not going to hurt anyone or yourself if you dont have the cash to do it immediately.

The first letter in BB should clue you in to why people would do things this way.

In general, I'd bumpstop the rear 1.5" - 2" and the front 1". I also find that quick disconnects do well for a 2" lift. Since it's a short lift, I think you may want to consider armoring critical undercarriage areas. IMO, from a functional standpoint, I don't think you need to mess with your steering (if you're going to run tires > 31", then I would upgrade to the XJ steering kit) or track bars.

Thanks for the info guys. Here's the Rubicon Express lift I was considering: Rubicon Express RE7030 - Rubicon Express 2" Econo Lift Kit with Shocks for 97-06 Jeep Wrangler TJ & Unlimited - Quadratec Obviously it comes with the proper shocks and spring parts.

"If" I install this, and I do plan to do "light" offroading, will I need to install any other things like control arms, etc?

I plan on running 31-10.50x15 tires on 15x8 rims.

Control arm exchange is not necessary for a short 2" lift. Unless you are doing a belly up and SYE .

I just want to add that while there is lots of good "do it the right way" suggestions in this thread....the fact is that there are about a zillion (or alot) of TJ's out there with 2" BB spacers with extended bumpstops and everything else is bone stock. (A re-alignment check is important after any changes to a suspension lift.)

Although I would LOVE to simply put the kit in and be done with it, the fact remains that I've never been one to "quit before I'm done" with anything. If the kit requires other mods to be done in the name of safety or reliability, then that is what I'll do. Not looking for stuff to do that isn't required, but I want to be safe and reliable.

Yep, I understand. But just know that some of those kits "with shocks" may be a worse (stiff) ride than a BB using oem shocks. So I think a good a approach is a 2" BB with Bilstein 5100's or OMEs if you are going to do shocks.

Looks like the shocks are factory installed, and with 110,000 on the clock, I think it's time to replace them anyway.
