YJ suspensions

So I took my YJ to the local Jeep place (not a dealer) to see if I got "took" or if I made a good deal. The guys seemed to think I did ok at 2500 for a 93 4.0 5 speed. One of the guys said "You know, of course, that your suspension is gone." Gotta say that no, I hadn't noticed. What a Noob. One of the fenders has a nice tire shaped cut out and I am only running 265s.
So of course I checked out the forum to see what I could learn about suspensions. I saw a couple of comments about YJ's not having coil springs. Gotta say I didn't notice that. I know that the YJ's have leaf springs, but I have seen lift kits with both.
So, after all that, here are my questions.
Do YJ's only have leaf springs? (I know I could go look but it is dark and cold at the moment.) Can you get a good lift with leaf springs? I have been looking at the Rancho 2 or 2.5 kits. I have read about leaf springs flattening out or inverting. Do leaf springs last as long as coil springs? Also, In order to maintain stability as I go up, should I get offsets for my wheels?
Finally, am I going to look like a total goober driving a lifted jeep with lil bitty 265's? (Can't do tires and suspension at the same time.
I know this was long, thanks for reading.

I just checked out Rubicon Express, the 4" lift is only around $31.00 more than the 2.5 lift, so I guess it would make sense to just get the 4. It just seems so......tall.

You will want to read up on slip yoke eliminators. As with a lift higher then 3" your drive-line angles may not be correct. The results of which range from bad to catastrophic.

Welcome!

Your wallet will never be the same again.

Edit: Go to Jeeps website and send your vin # to them and ask for a build sheet. That wil tell you what your Jeep left the factory with.

Howdy be sure to say hi to my sister if you bump into her.

Although I'm one of the original folks who got Rancho off the ground way back when I'm not a fan of their kits for the YJ - never have been for several reasons.

Yep, leafs will sometimes sag or loose their original height or arch. That's normal and to be expected. However, leafs that are designed superior, will last alot longer, and provide a much smoother controlable ride when coupled to good shocks. It's a balancing act and lots of companies take too many shortcuts and their products simply ride & last accordingly.

Yep, there are a few kits out there that convert the leaf spring suspension from leafs to coil springs. There are also ways to convert to coilovers, which are much different and have the potential to be far superior than either of the other when done right....but.....$,$$$.

Coil conversion kits tend to take shortcuts in my opinion, and they don't come cheap either. Plus there's the factor of a complex install compared to simply tossing in a new set of leafs & shocks.

I'm not a big fan of wheel spacers although they do have their place. An alternative to that is wheels with a different offset which places the wheels out farther, and wider wheels to fit the larger & wider tires.

Hey, welcome. Don't worry aout lift and tires at the same time. Get the lift right and then get the tires as $$$ can afford.


Hey Joe, Thanks for the advice ( as always) I use wheel spacers and haven't had any trouble. I agree that correct backspacing is important, but spacers work till the money for the right wheels is available!!

^^ doesn't that defeat the purpose of the lift? No matter how high you lift it, if you dont get bigger tires the axle is still at the same height, and it would look pretty funky, stock tires and a 4 inch lift.

This is true if you plan on running 265's forever.

But if you cant afford both the lift and the rubber at the same time, then its ok to do it one at a time as money allows.

Naw, it doesn't necessarily make sense to go with 4" over 2.5"...you're on the right path, there...you get a lift based upon what you wanna do with your vehicle and based upon the size tires ya want... I coulda afforded a 4", but went with 2.5" for several reasons...my type of usage didn't predicate anything bigger than a 31" tire, so the 2.5" lift made sense...I didn't want to outrageously affect the center of gravity...I didn't want to do all the modifications necessary to support a 4" lift, although it did require a dropped pitman arm, normally not necessary for a 2.5" lift, but in my case, it became required.

So, pick your lift based upon how you will use your Jeep and the tires you want to install...

The 2.5 kit comes with the nicer RE shocks, while the 4" kit comes with those cheap DT3000 shocks

ps..if you are looking at your front fenders..they are not 'flat' along the bottom edge, they all have a sort of 'simi circle' cut out in them..figure out what you want to do to your jeep, and then buy as you can afford..a 4" lift, will look great-if you are going with a 33" tire-eventually. it will also mean, new gears, sye and a few other things to work properly..go to car domain and look up yj's, they have thousands of pics of peoples jeeps and you can get an idea of the 'look and function' of what you want..welcome to 'yj-jeepin' empty your wallet and have some fun~fly
