: Converting YJ Leafs to Coil Over Suspension, any thoughts?

Found a few links on WARN Black Diamond’s and Pro Comps Coil Over Suspension to eliminate the Leaf Springs and go with Coil Suspension and it caught my eye so I figured I would ask some people who have seen this in action or who have it or know of it.

Anyway….what are your thought? Can the same amount of flex be found from leaf springs for half the price or is this something that should be considered seriously. Any catch to this that I am missing…..some things sound to good to be true. <IMG SRC="smilies/biggrin.gif" border="0">

I haven’t seen anyone running this combo so fill me in.

Below are the links I was talking about:

Buy a TJ <IMG SRC="smilies/biggrin.gif" border="0">

The Procomp sucks and the Warn is no longer available. Just go SOA with the leafs.

My one thought: If you wanted a TJ, you should've bought a TJ.

Note: These are not "coilover" kits as your subject line states, they are coil spring lifts. Two different animals.

In a general sense, these coil spring YJ kits are light duty suspensions and will not offer the flex of a good springover. And they're expensive.

The Black Diamond kit is coil-over and is available again (though for YJ's Im not sure).


Personally I thik a decent fab shop could build a stronger setup that uses better components for about the same coin.

If you go SOA and do it properly, you will out flex either of those kits for far less.

SOA: Wheels good if you have a traction bar. Springs only last a couple of years. Ride not that great (If you care about that sort of thing). Can get expensive with steering mods, etc. Durable. Simple.

Black Diamond: Wheels good. Good ride on washboard/rough roads at speed. Components are very stout (minus front arms). Very expensive. Not available yet??

Your thought doesn't count newbie so <IMG SRC="smilies/flipoff.gif" border="0">..... <IMG SRC="smilies/biggrin.gif" border="0">

Also,
YJ = $4,000
TJ = $14,000

You figure out the rest...... <IMG SRC="smilies/smokin.gif" border="0">

Whatever, dude. Go buy your little gay PC coil kit if that's what you want. Or go pound sand. What do I care?

As someone said above, for the amount of money it would cost you to buy either coil kit and have it installed, you could have a good shop fab up a 4 link with real coilovers that would outperform either of those kits by a longshot. But then again if you want to waste your money and get one of those just because its in a "kit" form, go ahead

This better start getting technical or it's getting axed.

This discussion has lots of potential - that's the only reason this thread is still here.

My bad Mo......just trying to see if a SOA is the better way to go then Coil Over.

Have heard pros about both.......

How much is a coil conversion kit? I'm looking into putting coilovers on my TJ and I'm looking at $1,800 just for coilovers - I haven't figured out fab work.

Well I have to say that this post is a load of CRAP!! The BD Coilover kit uses FOX coilovers at all ends. Yes tyhey are coilovers, not Coils in a cup as someone stated. I have seen this kit in action, and have to say it ROCKS. True it wil not flex like the coilovers that cost $500 a piece. The Coilovers are not always to blame for this. The link design should be made to maxamize the use of the spring. There are a lot of factors that go into a good setup. I want you to find me a chop that can piece together a coilover setup for under 2 grand. Will not happen. for 4 coilovers you are blowing about 2 grand right there, then the 4 link front and rear, you are into it a few grand more. I say if you go the coin, do the BD kit.

First of all, I've heard some great things about the Warn Kit and I've seen it outperform TJ's and Leaf-sprung YJ's as well. It uses REAL coil-overs and it NOT completely bolt-on, although it DOEA come in kit form. All that means is that the bracketry is supplied, as are all the parts. I heard that Black Diamond has been aquired and they will be releasing the kit once again. If they do, I would buy it in a heartbeat if I had a YJ.

As for those saying that it would be as cheap to have a shop custom built a coil-over suspension, you're smokin' crack <IMG SRC="smilies/smokin.gif" border="0">. Although I have never priced it before, I'm willing to bet that any reputable shop whould charge at LEAST $8,000 to design and build a FRONT & REAR 4-LINK, Coil-Over Suspension. If you do your own work, you could do it for less than the price of the kit. Oh yea, the PC kit sucks <IMG SRC="smilies/biggrin.gif" border="0">

BTW, Jason Bunch from Tri-County runs the kit in the ARCA series:

get the bd setup it is sweet and if...make that when you start braking parts replacements can be bought so it will be easier to to fix.

A friend of mine has the Pro-comp kit. He swears by it, I on the other hand have a different opinion. I have also seen someone, don't know who it was, with the black diamond kit.

If your looking for something that'll be really nice on road. The Pro-comp is for you. It is really nice and cushy. It doesn't do that well off-road.

If you want a good off-roading kit, the Black Diamond kit is really nice. I saw it out flex lifted TJs. I don't know what the on road performance of it so I can't help you out there.

I for one am waiting for the re-release of the BD kit. I was more than impressed with the kit when I saw it.

Who said 2 grand?


The price of the Warn kit was $2500. Warn was not selling this kit to individuals. You had to have it installed by a licsensed shop. Labor was running in the $2k neighborhood. Also, you had to have exhaust work done. We are quickly approaching the $5000 range if not already there.

I do agree that the Warn kit will outperform a TJ any day but the design and components used can be improved on.

The coil thing has been of interest to me for the past while. I'm looking for a 44 to put in the front of my YJ and when I find it I am pretty sure that I am gonna make the brakets to convert the front suspension to coils. A spring over would be easier but I seldom take the easy route when I have my mind set on something. First of all I think I would enjoy the challenge of setting up a coil suspension much more than a spring over. I have some ideas of how I will be making the spring brakets with some tubing that has the same outer diameter as the inner diameter of the coil springs. I have heard that the rear springs out of a ford aerostar are about the same spring rate and hight as lifted tj springs, I can get these really cheap, maybe 20 bucks for the pair. Any info on this?
I actually found someone on the net that made their own brakets for an axle upgrade on a TJ.
go to http://www.jeep-club.org/main.html and find the galleries menu on the header, choose video from the sub menu then click parent directory from the window that pops up and then finally click on Phils Mods.

Thanks for the info bro.....

It is not a bolt-on like the Pro Comp as some people think. I have read 3 huge articles and as you have stated it suppose to RTI a minimum of 1200......some of the articles I read showed almost 1300. Not bad for a YJ if you ask me.

Now the article I read in Petersons 4x4 did state that the kit must be installed my licensed shops and that the exhaust system had to be reworked but that will all be done in conjunction with the Lift anyway to include a V8 as well.

Thanks for the info....if they release it again I will be buying one most likely unless something better comes along.

Hey - that's me! The post about "Phil's Mods".
You can go direct to my stuff at
http:jeep-club.irtech.com/phils_mods

It was a lot of work but worth it.
Now I have a fairly solid "1TONJEEP"
4to1 and heavy duty output shaft is going into the D300 right now BTW.
Next will be shaving the diffs.

It uses a modified RE long arm kit (this is a TJ) and custom brackets. Ramps 1000 on a 30 degree ramp at full street pressure (with the 38.5's aired down it is much higher), but it is still VERY stable, not tippy, and rides great.

Let me know if you have questions, allways happy to help a fellow Jeeper. <IMG SRC="smilies/smile.gif" border="0">

I have the PC kit, and it does indeed suck. However, with some new control arms, it could kit ass. The control arms are really the weak part, along with the shock and lack of disconnects, and the fact that the rear sits 1.5" lower than the back...

HOWEVER, I feel comfortable going 80 on I-5 for my 8 hour trip home from school, so it did score some points with me...

A custom fabbed coilover settup will run you close to $2000 in coilovers, but you could just buy some RE longarms for the front and fab or get some other TJ arms for the rear and be set.

It will cost WAY more than a SOA to get the same flex, but it will be drivable above 70 MPH (on or offroad) and it's something different.

If you're just out to make a simple trail rig that works, go SOA. If you're into making a more elaborate setup just to see if you can make it work, (and you have the cash) think coilover.

but whatever you do, don't but the ProCrap kit....
