Converting CJ to YJ front suspension

I have a 76 CJ7 that I'll be installing a cut down Chevy Dana 44 SOA. I was hoping to use some YJ springs to maintain it's road manners. I have a D44 for the rear which should be fairly easy to install with new perches. I plan on putting 35's on it.


Question 1: Is there a thread out there that someone has done one of this b4?

Question 2: I've seen kits out there but is there anywhere that sells separate parts? I have the axle with perches and can fab the outboard rear mounts. Still need springs and shackles and taller upper shock mounts. (and I'm sure more bits and pieces)

Question 3: Is it worth putting used leafs in? I prefer a softer ride so would that help with flex?

Question 4: I heard it's safer to leave the rear axle under. I have 2.5 lift CJ springs all around now. Any idea how that will match up with the front? Maybe some small shackle lifts or ???

I know. Lots of questions. Any ideas or advice would be greatly appreciated.

spring over is going to give you about 6 inches of lift..used springs usually are less stiff than new springs. But, even new yj stock springs probably would not be nearly as stiff as 2.5 lifted cj springs.Nothing unsafe about spring over rear axle ,but you will need a traction bar setup to keep the rear end from twisting and bending the springs..I like running full width truck axles under mine and outboard the hangers front and rear

Cool thanks for the spring comparison. that's one thing I was wondering. I plan on putting a steel box bumper on it and attach the fronts there. I'm just looking for some ideas on out boarding the rear of the front leafs. want it to not only be safe but look ok for safety inspection.
Thanks for the help.

I don't know about the inspection but the ones I build out of 1/2 inch thick plate are a lot more heavy duty than anything else on a jeep frame

Cool thanks. Hoping to get a few other things done in the next few weeks then start the axles.
May be tight to join in some rides this spring but hopefully summer.

I completed a YJ spring swap on my CJ. You decide to do this? I will happy to tell you what I know?

Just curious, are you running a earlier dana 44? or something out a scout or ?
