I plan on putting a lift on my jeep and was wondering if I needed anything else to go along with the lift to complete it. My future mods for the lift are:

- RE 3.5 super-ride lift with rear springs
-bilstein 5100 shocks
- advance adapters SYE & Tom woods cv driveshaft

Was wondering if I NEED anything else to complete the lift like a track bar or shims or anything of the sort. Thankyou for any help!

You should probably get an adjustable track bar to re-center your axle but you could get away without one.

I planned on getting one but wasn't sure if it was a need. Thankyou for your reply!

Yea no problem. My buddy's running a 3-4" with a stock track bar but with the wheel at full lock it rubs on the control arm on one side because the axle is shifted to one side a little bit.

Have you looked into the Rock Krawler 4.5 short arm flex system by any chance? I know its a bit taller and a bit pricier than the RE lift but it comes with an adjustable track bar. The arms are all adjustable as well which is a big plus. I have installed a few of their lift kits and know its a quality product. They do offer an abuse proof lifetime guarantee on all hard parts, which they WILL stand behind. I know the RE kit comes with new rear leaf springs which has its benefits but when I installed my RE rear leafs they had a big arch to them which seemed to make the rear shackles almost perpendicular to the ground. Ideally you want a 45 degree angle. The Rock Kralwer kit uses a small block and an add a leaf which keeps a much straighter leaf spring and will allow for more downward travel and a better on road ride quality.

It's not even arguable that replacement leaf packs are a huge upgrade over stock. Ive watched stock leafs bend right up at almost a 90 degree angle. And blocks are one of the worst ways to lift a vehicle. They just create axle wrap. I'm not saying that's a bad kit, but it would be a lot better with new leafs.

And as for the shackle angle, that's what relocation brackets are for

Which lit kit are you talking about? And am I going to need relocation brackets?

mcnally

The Rock krawler kit. And I would just put the springs in and see where your shackle angle is at. If its straight up and down then you probably way to either fab up some brackets or buy some.

Shims will certainly improve your pinion angle. With an SYE you're going to want the rear pinion pointing directly at the T-case output.

Keep in mind that you'll need new centering pins when stalling the shims.

Make sure you get the right u-bolts for your axle.

Start applying your favorite penetrating oil now and use an impact gun to tighten your bolts before attempting to loosen them...works great and prevents a lot of broken bolts.

Am really going to need shims?

SeriousOffroad

The only way to know for certain is to install your lift/SYE and drive the rig at a variety of speeds. You'll know PDQ.

What's pdq?
