In process of getting all my parts together for a solid daily driver 1 ton 94 yj. Axles are Chevy kingpin 60 14 bolt combo out of a M1028. Keeping the 4.0 Ax15 combo but switching to a Dana 300 for passenger side drop. Hi steer, redhead 18:1 steering box, 7/8 heim steering links, disc brakes all around, ext. I want to end up with 37s on either a 17x9 or a 16x10 maybe. Oh and this will be a shackles forward not a shackle reversal setup. I will make a build thread once I get all my parts on hand. Springs, disc rear, and rebuild parts for my Dana 300 is what is left before doing so.

Here are my questions for the masses:
Has anybody ran the springs? How was custom service? Do you like the ride height or are they too big/small? Fender rubbing? Pictures are welcome.

RE 1.5" springs - heard alot of great things about them. 5 and 6 leaf packs available with only about 15lbs spring rate difference between them. Only down side is from what I've read and the few pictures that are not corrupted or not available due to Photobucket they are too tall. Price around 170 each (depending on where you get them)

BDS 2" springs- great warranty, none reverse eye but military wrapped. Only talked to one person who had them and said they are alittle bit stiff and he wanted to be lower by an inch or 2. Price around 160 each

Atlas suspension- custom made, thinking about 0-1" of lift. Military wrapped reverse eye with the option of offset center pins. Haven't talked to anyone or seen anybody running them. Price 900 for all 4

Deaver springs- custom made, 0-1" lift military wrapped ext. Price 650 a set. So 1300 for all 4

Alcan- custom made ext 600-700 a set depending on what you want.

Thanks everyone

Daily driver...on 1-ton axles...and 37s...running the 4.0L?

Anyway, RE is generally considered some of the better mass-produced springs out there. For the money, they're pretty darn good. If your budget is tight and they have something that fits your application, it might be the way to go.

My 2 pennies on the custom made springs: I haven't run Alcans on a Jeep, but after two sets on some Chevy full-sizes (Blazer and Suburban) I can tell you that they ride and articulate better than any off-the shelf spring you're going to find. Excellent off-road, and very good on the street with the proper shock. However, a buddy of mine ran a set of Deavers on his Blazer and swore by them. After 3 or so years of use, I could definitely tell that the Alcans had lost a bit of height - they weren't bad, but they were sagging. His Deavers were not. Remember, these were on full-size, heavy rigs, so you might have a different experience on a Wrangler.

I did what you're doing, only I was on 3/4 tons. 78 F250 D44/60 combo in a 92 YJ. Wasn't too bad of a daily, honestly.

That being said, no way I'd spend the money on the custom springs. With a leaf sprung wrangler, the difference in ride just isn't noticeable enough. To me, anyway.

I ran Crown HD stock replacements, 6 leaf springs. They held up very well and flexed great, and only $100 each.

From your list, I think I'd get the RE or BDS, leaning towards BDS. I had great luck with my BDS 5" springs.

Yes I'm keeping the 4.0 in this one. I have a spare 4.0 out of my 93 yj I'm going to get rebuilt next year. Not as stroker but better than the stock setup. I have 2 yjs one as a daily and the other is the toy. As for tons on the daily... Well i have 2 sets.... So both of them gets tons.

IMO 37s rate a Dana 60. Don't get me wrong I had G2 Dana 44s under my TJ for 6 years before selling it. Only thing I wore out was wheel bearings every 2 years and rod ends until I switched those out to heims. I just think do it right the first time and be done with it. May take longer but will be worth it.

Same goes for springs which is why I've been looking into a custom set. I can't find anything on atlas or deaver when it comes to yjs. I have atlas Springs on truck which ride great (the reason I'm looking at them). All the pre runners run deavers (why I'm looking at them). Alcan is on just about every forum I read along with the RE Springs. Those 2 always have good reviews.

Ok I'm down to RE 1.5s and atlas (have a set on my truck and love them). Re 1444 is the 5 leaf and re 1445 is the 6 leaf. I have a stubby front bumper with bull bar and grille hoop for Motobilt and plan on running either a warn 9.5 or Smitty built 9.5 winch. So I go ahead and get the re1445 all around or stick with re1444 in the front?

I have OME and next weekend they'll be in the back of my Jeep as spares because I have RE springs to throw on.

My axle wrap is horrible (I'm putting in a ladder bar to help correct it) and the OME springs are just too weak at the main leafs for the torque of the "almighty" 2.5L @ 4.88.

The RE main leafs alone are much thicker, but there are essentially two "main" leafs.

Look at pics of the RE springs and you'll notice that there is another leaf that wraps around one eye of the spring. Put this on the shackle end and you have an extra leaf.

The RE eyes are also exactly the same size, and the bushings are all the same. You can flip them any direction you please. The only difference is that the bushing sleeves are thicker/thinner for either a 1/2" or 9/16" bolt.

The bushings are also cheaper. I got a complete set (all four corners) for $65. OME were $35 a spring. I'm only replacing the rear springs though (for now).

Would love to hear how you like them. I too am building my ladder bar this week, just go the last of my parts in.

Did you add an add a leaf when going SOA? That's why I was looking into Atlas, alcan and Deavers because stock Springs won't hold without an extra main leaf "full leaf add a leaf" You are talking about military wrapped eyes yet another reason i want to run aftermarket springs. But yes an anti-wrap bar is a must

You're exactly right about the extra main leaf. It's definitely necessary.

I'm still figuring out the ladder bar build. I want it to be adjustable for any height but that's turning out to be more difficult than I thought.

This is how I'm going to build mine. Adjustable rod ends on the top of the axle and on the front of the ladder bar. Only fixed end will be on the bottom of the axle. Allows for additional length and adjustable for pinion angle

I used to use RE Extreme springs when I was sprung under. They were good for two months before requiring replacement. When I went Sprung Over I went with Alcan. My first set of Alcans went about 10yrs. Recently replaced them. I broke the rear last year. Didn't realize it because of the military wrap. Broke a front spring this year. Military wrap saved me again. I was running the old springs beyond my original weight design. I replaced them with new Alcans. There is a difference in quality of Alcan vs RE.

So you admittedly overloaded the springs and think that indicates a problem w them?

I've run 2.5" and now 4.5" re extreme duty on my yj and beat them REALLY hard for 10 years now between the 2 sets and never had them fail.....

I just put the RE springs on my Jeep. Going into the garage my rear bumper height was 24" from the floor. Coming out it was 29". I had to let air out of the tires.

That's 2.5" lift OME springs with a year and a half of heavy usage vs brand new RE 2.5" lift springs. They're also super stiff. I'm going to remove the springs again to take out a leaf so it lightens up a bit, and lowers. My pinion angle is way off again so hopefully with the springs settled in and a leaf taken out, I'll be sitting at a decent height again.

My shocks were maxed out so I currently have no shocks, I'm going to take the leaf out like I said, and do some bouncing to break in the springs. Then measure for shocks and a ladder bar.

The Jeep grew over time. Added armor. Added a child and associated stuff. I'm not complaining about the Alcans. They performed well outside of design specs. I replaced them with new Alcan springs. RE springs underperformed.

There are other custom spring manufacturers. Go with your preferred vendor. They are not off the shelf. Be sure to allow build time.

Cheap springs and long warranty are fine if you have the time to swap them.

I decided to go with a set of Atlas Springs. Ordered metalclock fenders last week and their yj is running 37s with 4.5"s of lift. That being said I'm going to get a set of stock height maybe 1" lift military wrapped and reverse eye setup made for SOA. Should net 5-7 inches of lift and clear them no problem with those fenders front and rear.

Bought my Springs last week. Stock height, 250lbs added spring rate for winch and full tube bumper, reverse eye for SOA setup, military wrapped and 1" pin offset. Also decided to use a set of Dana 60s I have instead of the 60/14 bolt combo. Going to use those in the other yj due to that one getting 42s.
