well, getting the ball rolling to link my cj.

the plan is to run a 3 link with panhard on the front and rear

running small and med size evo joints

coilovers on all 4 corners

full hydro steering with a double ended ram.

will probably kick out the front and rear axles at least a few inches both.

rig is an 85 cj 7 with hp44 front and d60 rear and they are full width out of a 78 f250.

questions
link setup. from what i understand, i want the lower links to be as parallel to the frame as possible. yes? no?? should the chassis end be located under the frame rail or inboard or outboard???

upper link will be on passengers side more than likely to because exhaust is on drivers side. this also should be parallel to the frame, but located on the chassis end up inside the frame rail. yes/no??? on the axle end, how high above the axle tube should it be mounted??

for the panhard, how do you determing how far down from the frame to mount the joint and how far up from the axle tube?? is it supposed to be almost flat at ride height?? or flat a full compression?? or something else??

i'll get in to my coilover questions later. that's mostly just trying to figure out spring rates really.

thanks.

and if this qualifys as 'newbie' just let me know.

damn, i've got a lot to read, finally searched the right terms.

i'm beginning to think i might be off in my orginal thoughts of link placement

It's a Jeep, can't you buy everything from a catalog? :flipoff2:

Yes you want the links to be as flat as possible without being rock anchors. You can locate them to the bottom of the frame or triangulate them to reduce flex steer.


upper link will be on passengers side more than likely to because exhaust is on drivers side. this also should be parallel to the frame, but located on the chassis end up inside the frame rail. yes/no??? on the axle end, how high above the axle tube should it be mounted??

My upper is mounted the same way. If I were to change anything, I'd add another inch or two of seperation at the frame end. It does lift a slightly on steep climbs. If you have a winch you can just hook it to the axle to prevent this.

A picture is worth a thousand words.

How about you tell us weather you have a steering box or an orbital valve? That is rather pertinant information in determining the construction of the panhard

Buy your coilovers with a 250 lb bottom spring, build the suspension and measure how far the spring compresses at ride height. Pick your favorite Excel spring rate spread sheet and go to town

And your welcome

ok, well, after looking around on the rig with JRT, he says there's plenty of room for a 4 link.

after looking at trusing the axle and the needs for that to mount the upper links, i got to talking to Dan at blue torch and he mentioned a reverse 4 link. where the lowers are standard triangulated and the uppers are almost straight. he's got brackets to mount the uppers and lowers on the axle that wouldn't require trusing the things.

so i ran some numbers thru the 4link calculator and got this:

now i relize that its not perfect for what will actually get built and all that but i think that its a resonable starting point.

i've got the same basic numbers for front and rear as far as anti-squat. only differences front and rear is the width mounting at the frame and axle.

comments and suggestions??

Updates?

:laughing: Yeah, how about it?
