Jeep rear suspension

[paintballaddict_6]

Hey, has anyone ever seen a suspension like this? How does it work? Looks like the guy just took a torch to a pack of leaf springs and flipped it upside down... Put the chopped side on the frame. Any idea on the advantages of this to a traditional leaf system?

[Ghola]

That is a 3 or 4 link suspension with 1/4 eliptical springs. The main advantages less axel wrap, and more suspension travle. The main disadvantage is cost, but its still cheeper than a coilover.

Yea Ghola is right, its could be either a wishbone 3 link, or a triangulated 4 link. Looks like there is a support going from each axle housing over the cast 3rd member. If there are 2 upper bars attached to that support its a triangulated 4 link. If there is 1 bar in the shape of a Y with a single mounting point to the axle and 2 to the frame, its a wishbone 3 link. Ive never seen a spring setup like that be4. Looks like the springs would be the limiting factor in travel though. Got any more pics of it?

Makes me miss my truck....airbagged s10 with a homebuilt wishbone 3 link that got over 14 inches of travel in the rear. should have never got rid of it.

At first glance it appears to be a Full Traction lift kit...

that spring setup looks like it would be really limiting on flex.

that guy cant be getting that much downward wheel travel because of the pinion angle. that thing is way out of wack.

Looks like he has the shackel on some sort of ball joint or something:


Here's the page that I'm getting all of this from, he has a pic of the jeep flexing pretty good.

This guy knows what he is doing, superb build.


Thats a 4 link with heim joints, kind of like a hard core tractor link.

Based on the pictures from page 2, I'd say he is getting excellent flex.



The crazy suspensions use a tractor ball

Edit: oops i meant Trailer ball **

[paintballaddict_6]

Wonder how it rides, on and off road. I wanna know how the guy built it!

[Hilltop Customs]

wow he did a nice job on that. I was hoping that the leaf sping isolated from the axle using a link like he did; or else that suspension would have all kinds of binding problems. IDK about off road suspensions, but for mini-trucks something like that is called a cantilever. Its required because the leaf spring pack is there only there to support the vehicle, the 4 link is what locates the axle under the vehicle.

You got any pictures of the front suspension?

maxama whats a tractor ball? Im not used to off-road terms, we have joints that are similar to heims, but weld onto the link bars and are much wider. They are similar to bushings, but dont bind up and allow for free rotational flexing.

paintballaddict_6 suspensions are not that difficult to build....all you need is basic geometry knowledge, be able to visualize whats happening in the suspension, and some welding skills.

I think the "tractor ball" he is reffering to is a heim joint that is made for hooking attatchments up to a tractor, definatally not as heavy duty as a purpose build offroad heim joint.

ohhhh, i know just what your talking about. heres a pic of the ones I was talking about. They are the best of both worlds....provides a large amount of articulation like a heim while being smoother and stronger similar to a bushing....only downfall is they are about 35.00 apiece But they will outlast a heim by a long shot...espically on a road driven vehicle

The front suspension was just a regular coilovers, I believe. Nothin special. Anyways, I have installed suspension lifts from a manufacturer, but never designed one myself. I have both some geometry skills, and am able to weld, I might think about checking out this suspension set up...

What type of Jeep are you going to but this on?

[paintballaddict_6]

I have a yj (94) with a ford 8.8 rear. I still need to check it out and figure out how they did it and all.
