new guy needs help with 4 link!

[elkins93]

Ok so im completely new to jeeps and crawling. Ive always built leaf spring trucks to play in the mud.

I picked up a 1993 grand cherokee laredo for 500 bucks and i want to 4 link it. A friend pointed me to Barnes 4x4 for the 4 link kit, ballistic for the truss's and foa for shocks. Im going to run a 60 front and either a 14blt ff rear or 60 rear. I weld for a living so the welding and fab is no big deal but where im completely and utterly lost is how to set this 4 link up once I start it.

Any help on placement of the links and or pointing in the right direction to tech articles is greatly appreciated because i want to donthis right the first time thanks.

Here's a few links that I saved when I was doing mine. I haven't tried mine yet but this is how it is setup in the rear. Upper links are 75% of the lowers length wise. Frame side separation is the same as the axle side so the uppers and lowers are parallel. Triangulated as much as I could on uppers and lowers.

He isn't a good friend if he told You to get foa shocks. ;D

I have a link in my build thread "half an inch off" if you want to check your four Link numbers with iPhone.
Edit: nevermind my link has been shut down.

First let me say numbers arent everything, BUT, search for the 4 link/3link calculator (excel sheet you can download) If I recall, when I went to find the 3 link version, Triaged's original was down, but Patooyee (who is a member here) has a current version on his web site. Do a LOT of research and play with the spreadsheet to get an idea of the characteristics. Packaging will dictate just what you can do. Personally, I like to get the rear AS on the lower side, the front (referred to as anti-dive) as high as possible, shoot for a roll center height that is near the center of gravity, a roll axis angle that's flat & as close to 0 as possible and the IC out in front of the rig...

Do as much reading as you can, and wade through internet BS, and remember, it will always involve more than you think(rear 4 links can mean you now have to come up with a new fuel cell/tank relo, exhaust mods, etc. and fronts can bring about 2 piece drivelines, engine cradles, exhaust :****: But its fun!
