REAR BUGGY LEAF OR COILS?...

[redrider2911]

Well I do have a whole extra set of rod ends since i just replaced my front ones. They are a little wore but could get me going on a rear 4 link. Another reason I was says buggy leaves over coils is because where the heck am i going to fab a coil mount on the "frame" in the rear. I could put them under the rail thats there but im not going to have much room for decent size coils. I would probably have to put stock coils under the back. And 8 inches isnt too tall. I want to run 35s with minimal fender trimming since this thing has to be road legal. I already stuff my 33s all the way up into the fender wells.

Rear links are a quick and fun project and should be recommended to even the most novice of fabricators. After all, a piss-poor rear link setup will outperform even a well-tuned leaf suspension any day of the week and twice on Sundays.

stay with the leaves. buggy leaf = 1/4 elliptical spring.

that is false...

1/4 elliptical is much different...

buggy is a variation of a 3/4 elliptical....

do some research, bud

Wait, wat?:wierd:
You think a 3/4 elliptical is going to be more stable then a 4 link?:roflmao:

Depends on who is doing the 4link...but in most cases, the suspension envolving leaf springs will be MUCH more stable than a 4link...why do you think alot of rigs have leaves in the front and links in the rear? Its for the stability...

Now, with that said...CORRECTLY built 4links are very very stable...i know this, ive built a shitton of them...but! a stable OFFROAD 4link and a stable STREETABLE 4link are two very different things... i dont know what experience you do or do not have in actually building 4links...or if you've only read about them...but from what I know from my experience...the simplicity of a buggy leaf setup (in his situation) would make that the better choice..cause more than likely he doesnt know how to build a tight 4link...

I've built a wishbone 3-link but decided to throw that out cause with the weight of a xj i couldnt make the wishbone strong enough with having to go around the oil pan and up over the driveline.

And now to replace that i built my own long arm 4 link. not triangulated, but one upper attached to the stock lower frame mount on the passenger side and two lowers attached at two points on the low profile drop t-case x member i made. And then a custom panhard. All adjustable ofcourse using rod ends.
Sorry I dont have any decent pictures of that yet.
I know how to fabricating and i know math. I dont know if i can afford to do a 4 link setup right now though. And I still dont see where I could mount the coils to get decent sized springs in there. Does anyone have any pictures of a rear 4 link on an xj that is still somewhat a stock body. Oh, and as far as a buggy leaf i am not exactly looking at an eliptical setup at all. I was going to run half a single leaf under a mount running the length of the leaf that would be welded to the side of the frame. When there is weight on the spring it will rest all the way against the long mounting plate and act just like a regular leaf setup until that tire drops and then the leaf will pull down when additional flex is needed. So more stable... Yes

that is false...

1/4 elliptical is much different...

sure as heck looks like a 1/4 elliptic spring

Well, that's what comes in that kit. But that kit assumes you already have a regular 1/2 elliptical leaf spring that you're adding to. 1/2 + 1/4 = 3/4.

"Regular" leaf springs are 1/2 elliptical. Full elliptical looks like 2 "regular" leaf springs stuck together to form an oval (elliptical). Half of a "regular" leaf spring is 1/2 of a 1/2, or 1/4 elliptical. :lecture:

That kit was discontinued, I have got to make time to go through my site and udate that stuff

semantics. A buggy leaf is only 1/4. not 3/4. I know how fraction work.

well this thread was good for something I guess. :eeks1:

 

[cj8rckcrlr]

no thats wrong, this is 1/4 elliptical...

BUGGY LEAF IS 3/4 ELLIPTICAL

 

[redrider2911]

So you guys dont seem to care anymore but is what im talking about a buggy leaf "3/4 eliptical" or am i talking about building a 1/4 eliptical which isnt even techniquely a buggy leaf setup? if im understanding you right...

I think you're talking about 3/4, which you'll get by adding a 1/4 to your current 1/2.

a 1/4 eliptical usually doesn't locate the axle at all. They're much like coil springs in that they only provide spring force and links are used to locate the axle. 1/2 (regular) and 3/4 (buggy) elipticals both provide spring force and locate the axle.

 

[redrider2911]

yea, that makes sense, everyone has a different take on it. Its kind of like how some people call a 3-link + a pan hard just a 3-link, but in all actuality it is truely a 4-link. So im thinking of doing the buggy for now but ill set it up with one leaf so that all it will provide is drop with barely any comression since the spring will just rest on the mount when weight is on the tire.
