I am building a cj7 and just got the rear suspension. I ordered poly perforance four link kit and going with dana 44 axles out of a waggoneer. I cant find any place that sells a completed kit four a four link front. If anyone can give me some sugestions it would help out. Or would it be better to go three link with a panhard par for the front

Check Genright I think they may offer a three link front kit. talk to them, they be able to help you out.

I went 3 link in the front of my 7 not too long ago. The ONE THING i would recommend with this setup is to plate the shit out of that frame where the panhard bar hooks up to the frame. I mean top, sides, and especially the bottom.
I didnt do this and had a complete frame failure about 4 hours from nowhere. My axle shifted about 1.5 feet to the left and the only thing keeping it from venturing any further was the brakeline! CJ frames are notoriously weak (notice the bottom of the frame right above the front axle.....chicken shit tac welds holding it together).
As far as functionality and performance, i love it.
