I bought my Jeep with an unknown brand 4" lift. Over the last few years I've been replacing and upgrading suspension components. The last suspension parts from the PO are the springs. When measured, I have 4" of lift in the back but only 3 1/4" of lift in the front. I assume that 3/4" difference is a combination of sag and the additional weight of my front bumper and winch.

So what I'm now looking for are front and rear replacement springs that will keep me at a true 4" of lift. I want to stay at 4" because the shocks and rear driveshaft that were replaced based on the 4" lift.

Some additional info about the Jeep:
2001 TJ Sahara (so I have the 6 cylinder)
Front bumper and winch weigh about 150 pounds
Has a swing away rear carrier with a 33" spare
Soft top
No armor
No rear seat

I think Currie offers multiple spring rates? How do I get the correct rates for my application? I'm open to all suggestions.

Note: I don't want to add a 3/4" coil spacer up front. I feel like that's not addressing the issue of a spring that doesn't have the correct spring rate.

You're right about Currie. You can call them up and they will set you up with the right spring rates.

As you already know, you can't go wrong with Currie. My complete Currie 4" lift should be hear soon so I'll let you know how I like the springs. From what I read everyone who has them loves it!

There is no way to get a perfect lift amount from a spring unless your rig happens to weigh the exact amount as the one they used to build the spring. You might get lucky and hit that magic 4" number but I'd never bet money on it.

Is +/- 1/2" out of the realm of possibility?

Not at all. I just want you to know how springs work and why they may or may not produce the results you are after. Springs are built to a specific rate which is X number of pounds will compress the spring 1". That is the spring rate. If you don't have the same number of pounds compressing the spring, you will not get the same amount of compressed spring height.

Thank you, that's why I was asking about the spring rate for my application. What I don't want, for example, is what happened to a lot of people buying the Metalcloak springs expecting 3.5" lift and ending up with 5.5" because they were designed for a much heavier vehicle.

I thought I had read that Currie springs were available in different rates, but I don't see that on their website. Savvy does offer two different options of Currie springs so maybe it's best that I just contact them directly.
 
You have to call to order. OR you can go to 4LowParts and get 10% off Currie right now CE10 is the code. 4LowParts gives the descriptions. Either way, you need:

CE-9132FP is 4" for the front
CE-9131RH2P is 4" for the rear

That will give you a nice level lift. They make a RH3P rear that is one inch taller free length for LJ's and "heavily loaded TJ's". I got them. Rear was slightly higher to the trained eye. They may settle. I've blocked it out lol. I absolutely love the lift. You seem like you'd notice. I did my friends Currie 4" lift with the RH2P's and he's perfectly level.

They make an F1P JK front 4" spring but that's too light for a 4.0 TJ. The FP is for TJ, LJ and JKU.

Also, keep in mind that the 4 inch lift components that you have on the jeep currently, surely allow for some variation.

I second this. Ricky Garza (@Garza) of 4LowParts is on this forum. PM him or give him a buzz, he will hook you up on anything Currie for a good 'forum member' price.

I bought my 4" front springs from OME heavy duty (220 spring rate the stock rate is 170)I run a heavy bumper winch with wire front hoop no sway bar up front and I have little to no body roll even on the highway

Honestly I'm just looking for information at this point. I have no money left for additional parts right now so I don't want to bother too many people. I will definitely get in touch with him when I'm ready to buy though.

I didn't know OME even made 4" springs.

All of my research pointed to them giving a much larger lift than advertised, so I left them out. Although that could have been from people not researching the proper rate.

Thank you, that's the kind of information that I was looking for. I don't care if the Jeep sits level, it wasn't designed that way and it hasn't been that way for the three years that I've owned it. :) I just want it built right with quality parts. I hope that makes sense.
 
Makes perfect sense. Most companies make it a fairly straightforward process. Quality has always been my number one concern.

Here's right after my lift. Slight rake.

And a couple months later. Different angle and light. Can't even tell.

I called Savvy today. They have a propriety spring made by Currie, but only in the 3" version. So from my understanding Currie only makes one version of their front 4" spring and two versions of their rear 4" spring.

Well, I have the 4" Currie springs (and their complete lift) going on soon. I'll be happy to report back and let you know if it really does turn out to be 4". My Wrangler is a good one for a test subject as well. I've got a hard top, full doors, heavy front bumper, winch, etc.. In other words, if there's any chance of it sagging a bit, I've got all the gear to do it!
 
Yours is kind of opposite of me though, so I actually hope that yours does sag a bit. I have a small front bumper, half doors, soft top, no back seat, etc. if yours stays at 4" then mine will more than likely be higher.
