steering advice CJ7 with a spring over lift

Im new to the jeep world and I just snagged a clean 1980 CJ7. It has a spring over lift on it currently. It drives pretty nice considering it has 35"s on it. It does not have a steering stabilizer on it and it has the original steering set up from 1980 with no modifications other than the spring over lift.

I have every intention of making this my daily driver. With that in mind, what are the first two steering upgrades that I should consider so that my steering is absolutely flawless that would allow me to get up to interstate driving speeds without feeling like im about to go on a kamakazee mission I may never return from? lol

Add a picture showing how parallel to the ground the drag link is and take a rough measurement of the caster. I assume it’s a D30 axle?

Here are those pics. I took a few to cover different angles. It has a z-Link? Also, I’ve heard of flipping the ends, but if I do they will hit the springs.

Even though you have a z link drag link
It’s the joint locations that matter
As such you have a large angle between the effective drag link and your tie rod
You probably have a lot of bump steer
Look into a hi steer modification

1977 CJ5 is a CJ build ever really done?

2005 TJ also gone

Definitely look into a high steer setup. The most popular ones install Dana 44 knuckles onto the Dana 30, though it may be better to just upgrade to a Dana 44. That is what I did.

Every 20 minute job is just one broken bolt away from a three day ordeal.

What kind of wheeling you want to do? If you ever put a locker in the front with 35” tires, your D30 will be toast.

I would recommend two approaches (either should have 6 to 7 degree of caster) and give you a decent highway ride.

1) $$, change to spring under, 3” to 4” lift and 33” tires, drag link flip and optionally tie rod flip.

2) $$$$, swap out the D30 to a D44 with Chevy flat top knuckles and high steer, YJ springs, 35” tires.

I am not familiar with AMC20, but suggest rear axle is as strong as front (so for option 2) D44 of Ford 9”)

Mine had that exact same setup on it when I got it. It was dangerous at any speed over twenty mph. Honestly, if you are looking to fix all of this and stay on the cheaper side, I would recommend going back to a spring under setup and going down in tire size. SOA can be done correctly, but it takes a lot more than just flipping the axles to the underside of the leafs. There is a lot of geometry that goes into the steering angles, and castor angle that needs to be correct in order for it to drive properly

This is what I am discovering. I paid a shop waaaaaayyyy too much to have this SOA put on so I figured they new what they were doing down in Dallas. Thing drives way worse than when I originally took it to them🤦‍♂️

I think I’m gonna try and have steering correct the right way. It’s got an appointment to 4wheel parts shop for an alignment assessment.

First link is the new knuckles for high steer. This kit comes with a single hole pass side knuckle, you can either convert to the 'T' style steering or call and have the pass side arm swapped for the dual hole arm. 3rd link is the adapter plate to use your current 2 bolt brake caliper mount.

Did they put a traction bar in the rear? if not, that will be the next thing you will want to add before you start having axle wrap issues and are busting ujoints

A drop pitman arm might help too.

You would think so, but from personal experience, it doesn't.
