Hey guys i dont know if there is another technical artical about this i am thinking about dovetailing the front of my project jeep and was wondering if there was already an artical in this and if so could you give me the link.also has anyone ever delt with 1/4 elliptical suspension setups,i would like to know more about them and how to make one.thanks in advance for the info and the help

 

anyone have any answers for him. i would be interested in reading up on this as well.

 

I found this using google:

I've thought about running a quarter elliptic in the rear as well. It's old school, but it works.

 

Make it easy just go buy a toyota cause that is what it looks like

 

definately not a good idea for a occasional street driver, definately not a daily driver.

 

That would be wicked scary on a streetable Jeep.

 

1/4 elliptical's are a hard set up to get right. I've helped set them up in the past and there is no way you'd want to run them on the street..

 

Is this setup better than coil spring-4-link setups? I don't see why people don't just convert to coil springs and run 4 arms since it works so well and is easier to setup.

 

Mudd I have seen this done a few times but the frame/unibody needs a lot of reinforcement b/c it is not designed for rear coils. The flex is unreal but there is an extra 100 pounds or more of steel reinfocement for the upper coil bucket and there is the need for a crossmember for the rear arms. An aweful lot of work for the small gains unless it is a trail buggy only.

 

It seems going with 1/4 elliptical, you need a crossmember for the arms on that setup too plus the coil spring bucket reinforcement would actually do you some good since the cherokee is a uni-body vehicle and could use some extra beef under there. The jeep wrangler TJ has front and rear coil spring setups and works great, on and off road. I can see a cherokee with the same setup doing just as well. Right?

 

Yeah they flex great but that area of the frame/unibody is a hard area to build into b/c of the shape each of several pieces needs to be hand fitted into place and welded. The TJ has a better frame and comes from the factory with coils so no hand fitting required.
Your idea is sound but the work involved is quite extensive. Don't want to discourage you at all just want you to be aware of how much work is going to be needed.

 

Yeah i understand. I don't have much experience under my xj, except for when i installed parts. I never really got the chance to just sit under there and look things over, how it's setup and such (frame) so i don't really have an idea of what would go into it when building a coil-sprung setup back there. I guess that's why they went with leaf springs

thanks blue

 

Like I said only seen it done on dedicated trail rigs that were not ever gonna be road ready again. It took a whole week to fab up the buckets and trial and error fit the reinforcement in place and then all weekend to get it welded into place and gussetted up. But that thing would go places that dedicated rock buggies were the only other things getting through. Never saw the others on the trail just in the shop being built.

 

Wow this is some great info,and just to let everyody know that if i do choose to do the 1/4 elliptical setup it will be a trail only rig,i wouldnt want to chance anything with driving it on the street.thank you guys for the great info
