Coil springs how do you keep them in the Jeep, and still allow the axle to droop to its full potiential ?

there is a bunch of debates on "controled droop" vrs just letting the shat free hang. most of the setups i have seen ran the bumpstop down the middle of the coil and used this as a locator for when the coil comes off the top pad (TJ style) with U-bolts or clips holding the bottom of the coil

USMCDOC is right.......not bad for a squid:flipoff2:

Just jerkin your chain, man.

Yes, run them TJ style, it works.

I am about to do the coil setup and i have decided to attath the bottom end to the axle with some sort of clip, and let the top hang loose like what they have said above. in the front i will prob have a pipe going down the coil from the top to keep the coil located in the front, this is that dildo lookin thing on TJs and XJs. The rears i might attach top and bottom, depends on how it flexes when i try it. Sam's Slinky jeep on sierra rock crawlers attaches his coils with clips on top and bottom, and if you look at any pics you can clearly see that it has no efffect on limiting his flex. but this could be due to a well done link setup too. post pics when ya get the coils on

i know how the TJ does it that is what mine is (TJ) but the axle will drop so much that the spring will fall off the bottom of that shaft... i cant extend the shaft because it is also the bumpstop.

i will probably settle on limiting straps in the front... for the rear I was thinkin about a 1/4 eleptical spring (single leaf) attached to the top coil cup and attached to the frame then retain the spring in the cup after the coil droops completely the 1/4 eleptical spring would start to droop

i could call it "COIL ELIPTICAL":D

front

damn, that sounds like a very interesting idea!! i like that alot...but i think your front will be fine if you make a new bumpstop that is a lil longer, cuz yor coils seem ALOT bigger than that bumpstop was designed for, i think for the front and rear, you will be fine with the flew you will get if you just limited it with straps, but then again every suspension is different when it comes to droop versus amount of actual flew your getting...i hope this isnt as confusing as it sounds.

If the picture is how you have things setup and plan to stay that way, I can agree that the bumpstop is waaayyyy to short for that spring. You're a few nano seconds away from overcompressing and ruining them.

The clusterfuck of "Coil Eliptical springs" sounds like an over complicated mess that would not locate the coil well enough at rest and offer little if any benifit over the front setup on droop. I would try containing both ends of the coil to see if you can get some of the stability people get by running rear swaybars.

in the pic of the front the bumpstop is not installed yet... it adds 2"-3" to the lenght of the upper retainer

completely compressing the spring will not hurt it .....Stretching it on the other hand will hurt

Where ???

Flew ??? i hope im not getting the FLU

here you go and this also might give you some ideas:flipoff2:

I agree. On my TJ, with TeraFlex 4" front springs + 1" spacers, I have a spacer on top of the bumpstop cup (1" ) + the RE "pucks" that attach to the lower spring mount, raising the surface up maybe 3" (?). I also have limiting straps that kick in just before the shocks fully extend. At that point the springs have dropped away from the top mount 1-2". With my shocks converted to "eye-to-eye" style, thus spacing them down 2" or so, I am able to use all of the shock travel (11"). I the rear I've got extended poly bumpstops and some 1/4" bar stock bolted to the lower mount to retain the bottom of the coils, along with limiting straps and relocated lower shock mounts.

Anyway, that's my setup and it works pretty well.

on the drivetrain direct built 44 we just installed, there are just plates with bolts going through the bottom mount, so if theres not a hole in the center, drill and tap one, then cut out a round plate and bolt it

there's always the hinge dealy they used on the 6x6 TJ...

Kind of on topic.. I found a cheap and slightly ghetto way of holding down the spring at the axle end that usually gets put on my projects at the last minute.
Ya know that little chunk of tubing that falls out of the notcher when you're doing a fishmouth? Take one of those, cut it in half, lay it over the spring and weld it to the coil pad. Works great. :beer: I don't know how it would work on a spring-in-tension arrangement, but I always run the free-fall setup.

What is the advantage of having the spring drop out of the bucket in the first place? The tire will have no contact pressure once this happens resulting in nothing gained.

Am I wrong?

What, the axles, wheels, tires, and half of the links don't weigh anything?
Even coilovers do the free-fall, or else they wouldn't need tender springs!
