I just put a lift on my 01 Sport. I got it off of e-bay it is a black mountian 4in. lift ( made by rough country actually)came to 507.97 or something. Took about 11hrs. to install with the help off my friend. (first time. looking for the correct tools took the most time though.) It rides good and I didn't need a sye but plan on getting one anyways. I have no driveshaft vibes or deathwobble so all in on I'm pretty happy. Only complaint is it didn't have the brake line extension brackets, but the company said they'll ship them right out. here is some before and after pics.

4" is the height where most agree that a SYE kit and CV driveshaft is strongly recommended. Those who say they're not needed are most often shops who try to low-ball the cost of their kits. The OE driveshaft's length becomes too short at that height which means it could be pulled right off the t-case splined slip-joint in the right offroad conditions.

And that height steepens the rear driveshaft angles enough that it takes both a deep t-case drop (lowering kit) and usually 1" taller motor mounts to reduce the angles enough so the vibrations go away.

In other words, 4" of suspension lift is where things start getting expensive. What I always recommend in these situations is a 3" suspension lift with a 1" body lift which is a good compromise. It gives the same overall tire clearance without the expense of the SYE kit and CV driveshaft being required.

I run 4" currie coils with just a t-case drop... trust me.... get the SYE. I wish I could afford one but I'll have to wait a bit. Mine hasn't had problems pulling out even though my setup is pretty flexy for a shortarm; but the vibes are outright obnoxious.

 

[Jerry Bransford]

the vibes are outright obnoxious.

You cannot just live with drivetrain vibrations, they will definitely damage the seals and/or bearings in either the t-case or axle before long. I'd do something asap to get rid of those vibes... either more t-case drop or a set of 1" taller motor mounts. But both might be required to completely get rid of the vibes.

what about going with a 2" budget boost and a 2" body lift... i am shooting to get those 33s under there.. but i want to keep the price down.. mainly because i only want this for looks.. if i decide to go off-road then one day i can change up my suspension.

The reason i say 2" budget boost and then the body lift, is that i think it would cost less for the shop to install the budget boost than a 3" lift...

Also, what do ppl think about a 3" body lift... I am not that familiar with body lifts and in general i have tried to avoid them... but i would like to do all this without having to get into ordering a SYE and a new driveshaft..

The labor to install 3" springs is the same to install 2" spacers on top of those springs.

 

[Homerjay4242]

again not to sound retarded... but i can just change the springs and the shocks to get an additional 3" w/o having to change anything else... do you know a place that has a good 3" kit..

I think this might be the perfect option for me.. i can run 3" up, go with 32 x 11.50 tires and then try to fit them on a decent rim, or maybe the stock rim with a 1" spacer.. i have 30 x 9.5 now...

 

[kameel]

No, you need to adjust the pinion angle of the rear driveshaft..
If you're lucky a 1" transfercase-drop will do the trick.

The labor to install 3" springs is the same to install 2" spacers on top of those springs.

Bingo

 

[Homerjay4242]

so i would need the 3" kit and a transfer case drop of 1" to avoid vibration... does anyone know of a decent 3" kit... i would love to go with 4" but i do not want to spend all the additional money on the SYE and a new driveshaft..

 

[Jerry Bransford]

A 3" lift will still produce vibrations but they will be easier to eliminate and you won't absolutely need a SYE kit and CV driveshaft.

 

[jeeperman]

The best option for you IMHO, would be to look into an Old Man Emu suspension system. It will lift your truck about 2.5" and give you room for 32" tires, while giving you an improved road ride. If you are looking to spend less money than that, I would look into doing some 2" lift with a 1" body lift to clear your 32" tires. And as stated above, your labor will be the same to install spacers as new springs. Good luck with your search for the "perfect" setup! We have all been looking for that forever! The worst part is, yours will be different than the guy down the street. So go with what your heart (and wallet) tells you, and let us know how it works out!

I know I'm really not too concerned about it - bearings are still ok for now, I check the whole rig from top to bottom especially in those departments about once a month (running this setup for about 1.5 years) and I don't plan on holding onto my 231's tailshaft and the Dana 35 pinion shaft much longer I'm just cool like that lol

 

[Homerjay4242]

right now i have 30 inch tires on my X.. so if i put a 2" budget boost i should be able to get 32s on there.. My question is, how hard is the install for the budget boost kit... it is spacers and shocks... is this easier than putting on a full 4" kit...

i am not sure if i would do this myself.. or have a shop do it.. but i am trying to figure out what it is going to cost me for the install..

i saw a mice pic just before of a jeep with a 2" RE budget boost and 32s... i like the look.. it is more aggressive than stock and it is not so far over the top that i will need more mods to the jeep... plus i should fair better on gas with 32s.. and that will help since this is my daily driver...

 

[JeepCrawler98]

A 'full' 4" lift kit will have new track bars, control arms, brake lines, sway bar disconnects probably, etc. - is it harder? nah. If you can do a BB you can do a full lift 'kit. Is a 4" full kit more involved? yeah.

If you want a write up on my BB install when I still had it check out the article I wrote:

So I am in the UK and have just purchased a left hooker wrangler TJ. It already had a 3" black diamond suspension lift, and I do not notice any vibration but the seals on the front and back diff are leaking oil just where the prop is connected. Is this because of the lift or just bad luck?

get the 3" full traction kit. It's a good price and comes with a new front track bar.
