How much lift can I get from stock replacement leafs

--------------------------------------------------------------------------------
I have a 94 YJ with 134,000.It has the stock springs.It's running 30 by 9.5 by 15 tires.I'd like to upgrade to 31 by 10.5 by 15 tires. I was curious if I replaced the worn springs with factory replacements, would that give me the needed lift for running the 31's? Or should I just put on a 2- 2.5 lift kit and be done?

I have a set of 31-10.50s I haven't tried yet but I think you'll be fine on the springs you've got right now... And while I am not an advocate of body lifts, I've read enough anticanman comments about the benefits of 1" body lift that I think if you need a little the 1" body lift is a super low cost solution.

We have no way of knowing how bad your stock springs are sagging. You can find out by going to the FAQ stock specifications and measuring the height of you rocker panels then subtracting the additional height of the 30" tires you are using and comparing that to stock rocker height which I believe is 18"

Here is a chart that can help determine what is possible. Keep in mind stuffing the fenders with oversize rubber without lift will cause the tires to rub on anything except a JC Penney parking lot. Which is ok if that's all you plan on doing.
I don't dig the overstuffed wheelwell look, all show and no go.

Here is what mine looks like on 31x10.50s and stock (as far as i know original) suspension. PO put those wheels on and they rubbed the flat flares at full lock until i trimmed a bit with the dremel. For the difference in price you may ad well lift it though. I cant wait to get mine lifted.

My backspacing pushes my 31x10.50r15s out past the fender. I've got a 3" body lift, so clearance has never been an issue, so I can't tell you for sure.

But as far as lifting a bit using stock springs, you can definitely get a moderate boost. For reference, my springs were basically perfectly straight when I took them off. I bought rear 6 leaf springs (18202.22) for the back and gained 3 inches. I bought rear 5 leaf springs (18201.23) for the front and gained about 1.5 inches. I'm quite happy with the combo and could easily put in 33s without rubbing.

As reference, here's mine with 31x10.5's, stock suspension and 1" body lift. No rubbing unless you do very tight turns.
