RE: Make my own Roll Cage

Hello..... [beating_a_dead_horse]Take that! You dead smelly topic[/beating_a_dead_horse].... now I feel better....


I am planning to do a 4-link with buggy springs on the rear of my CJ-5. The way that I wish to have it is to give me a NEGITIVE approach angle from the rear.... ex.1

Nasty, huh? I am knowledge thirsty and was wondering if there is ANY information that any one wishes to share with me.... My end vision is that of the green CJ-5 in "Rides That Impress Me, What Impresses You?" http://www.jeepz.com/index.php?name=PNphpBB2&file=viewtopic&t=328035&start=45
Thst is what I want, that and/or the YJ further down on the same page

The 4link part is just the means by which you locate the axle. You can use several types of spring setup to support the weight of the vehicle.

Are you sure you don't mean a 1/4 elliptical setup? I thought buggy springs just referred to a 3/4 setup? With buggy springs, you don't need links, the leafs still locate the axle. With the 1/4 setup, only one end of the leaf pack is connected to the frame so a link setup is needed. There are different link setups too.

Do you really need all of that, or do you just want the "ultimate" setup, or what? That's alot to do man, not to mention alot of money.
 
That's what redrooster has under his. A 1/4 elliptical four link setup, but I don't think he has airbags. People may refer to those as buggy springs too these days, I don't know.

I'd go coils or coilover if you want to do a link type setup. The Airshox deals are nice too if that's your bag, but again overkill for anything but competitive rockcrawling.

That's not the suspension, that's traction devices, a low crawl ratio, and a good departure angle (tail bobbed) allowing him to do that. That could be done with a regular old SUA setup.

All these 4 link, buggy, elliptical, etc setups are very impressive, but I have to doubt the necessity unless competition is something you are shooting for. If that is the case, you'll need a trailer and a tow rig because anything competitive will certainly not be street legal.
 
RE: Re: RE: the end of my world...

If you look at that pic, the rear of the jeep sticks out further than the tires, his rear would have hit first if he went straight on. According to his front tires, it appears that he went up it with his rear driver tire first then turned into it straight. Going by this assumtion, that could also be done even if spring hangers were in the way

Without any sarcasim..... would the 96° rear approach angle have anything to do with it?
 
RE: control arms

Rear is always departure angle, and it looks like it is 96º which means the tires extend past the tub in the rear. The pic is a little deceiving.

Anybody else think the ramp in the foreground had anything to do with helping that jeep onto the wall? :lol:

AFAIK buggy springs still refer to 3/4 elip. and the above pics are 1/4 elip. with a 4-link setup. Give me good 'ole leaf springs for a KISS suspension.

My exact thoughts. I like the idea of having leaves so much that 10-15% of me almost wants to convert the front of the XJ over if I decide to go big with it. Simple axle location, simple fixes when it breaks, cheap parts, and the right leaf pack will handle whatever is thrown at it.....even that fancy high stepping rockcrawling that people are hooked on these days.

I'd really like to see a real comparison between the different types of setups.
All vehicles should be the same model and similarly equipped. Same tires, same drivetrain, each driver pilots each rig to remove driver error from the excuse list. Something like a bunch of 4.0l 5 speed YJs on 35s, but with different suspension setups. Oh yeah, and in different types of terrain. That would be the sweetest offroad comparison test yet.
 

RE: New Jersey State Inspection

So a SOA CAN do this....

How would this be accomplished.... a simple SOA or I've heard of loosening some suspension parts to gain flex.....
 
Yes an SOA'd rig could do that if it had the right leaves in the packs and everything else was set up right for that particular vehicle.

I'm guessing it's a Keep It Simple, Stupid type of suspension.....
 
Keep It Simple Suspension.... The less to break, the less will break.....
OK, does ANYBODY know how to get a SOA to do this.... or will it be trial and error for me?
 
RE: cd stuff

It really depends on each specific vehicle (mostly due to weight). What kind of engine do you plan to run?
