OK so Im at the shop, wrenching away minding my own business when all of a sudden one of my crazy idea's hit me.

I think its so nuts, it just may work.

I think that if you get some 4" lift springs (this is all on a YJ) and use ONLY the main leaf you can use it as a "control-arm" so to say with a set of coil overs. You get what I mean? The main leaf of the spring packs will locate the axle, providing VERY little spring rate...Then mount up a set of coil-overs to act as your springs/shocks.

I think tis would work if you used a 4" lift main leaf because its longer and will aloow for more drop, mount it up SOA along with a revolover shackle and a Z-box. I dont belive that the z-boxes or revolovers will have any negative effects as they will be "undercontrol" by the coilover...not just floping open and shut.

Only problem I see is that there would be some major spring wrap issues in the rear, that could be put to an end with the use of a Bam-Bar.


So...you think it will work?!?!

discuss, flame, rant, question, or at least say something....

dude your crazy!! there i said something are you happy?

besides coilovers are $$$$$$

if it were that easy, it'd be done by now pilgrim!

If I only had the $$$$$ for coilovers!

That actually sounds like a good idea, in theory. I was looking at my friends stock 04 tacoma yesterday, and noticed his rear springs are about 4 ft long, longest Ive seen, and they are really flat and mounted on top of the axle.

nope no good.


my bet is that the leafs would not only spring wrap but also twist. and that would mean "ker-snap".

keep day dreaming on company time though, ya might come up witht he next big thing.

You will never know how it works until you try it.

Just be sure to make a movie of the first test drive.

The carnage from the ensuing spring failure will be fun to watch.

guys haev been doing it with lowrider pick ups for a while. Rear end will 'walk'... one side wrap forward, other side wrap backwards, under heavy throttle or uneven traction. this leads to broken springs really quick, and when your springs/links break.... you just bent $1000 in coilovers. and that will just riun your weekend.

I agree with clemson krawler. Theory motion of moving straight up and down seems like it would work, but add torque and forces pushing left to right on the axle, and that will be a lot of movement. The reason a pack doesnt move is because your trying to move many leafs which is like a solid peice in theory of 2"-3" thick. I still think you would be limited by the leafs ability to twist when a heim and links would be much better. Also if those coils arnt centered on the axle, they will cause rap but putting a torque on the tube.

This here will eliminate all and any axle wrap:



Als mount one coil over on the backside of the axle tubes and one on the front will help aid in wraping issues.

However, Im not saying it will work... hehehe but there's only one way to find out!

Skyjacker makes a 6" monoleaf (one single spring)lift kit.They also make their 5th link rear traction bar,but that would cost you close to $1500 not counting the coilovers!!

thats quite the traction bar you got there. thats pretty ingenious. your guite the fabricator. i think you have a pretty good idea it may need some tweaking though. but you are on the right track,
HA HA get it.

anti wrap yes that will do, but to control side push and twist that comes from the axle's curved travel when it compresses and droops, "NO" it won't a track bar is needed for that or better lowers than leafs.

Yea, actully I think for the trouble you would end up going through trying to get the leafspring/coil thingy to work you might as well just fab up some link and toss the leafs aside.

Ok Ren...try this for size. And it may sound equally as nuts, but here goes.

Use the full pack, but cut off the back portion just aft of the axle, as a link or control arm. Use your cool anti-wrap bar, and the coil overs. Or even conventional coil springs and existing shocks. Yeah, a track bar will most likely be needed. But if you can get the axle wrap under control, then this *might* work also. Giving some added strenth over a single leaf used full lenth. My biggest concern with either set up is when having to back up under a load. Or will your anti wrap gizmo work for both forward and reverse?
The reality of my last thoughts are...this could actually be too flexy!

Dennis you would also have to have atrack bar with this set up. Man seems lie a lot of work. Either way!

You cant just cut the leafs, this will not work. Sounds like youre thinking of quarter elliptical leafs, and they are very specific when being fabricated. Maybe if you put a cap on the end and welded the ends of the leafs together, but still dont know how that would hold up.

I wanna see it done. Just experiment on a friends jeep first!
