Wells its all my design. We are offering the coilover conversion as a kit now.
Thanks for the link man. I get quite a bit more in depth. I am using this calculator.

So I worked on the jeep some more today. Got the center frame stiffeners and front frame stiffeners welded on. Notched the front truss for oil pan clearance. Got the track bar bracket welded on. Painted all the control arms, mounts, and crossmember. Then assembled everything. Getting excited that it is all coming together but I stll have a few clearance issues to address.
So heres how she sits.


Welded stiffeners and track bar bracket.


All the shiny painted parts.

So track bar/tie rod. Only about 2-1/2" until contact. This will be remedied as soon as I can get some one to trade me knuckles with the stock steering arms intact. By moving the tie rod onto the stock steering arm I will have at least 6" of clearance.
Ride height

Contact

Axle truss/Oil pan. At ride height there is about 5" now before contact. This will be remedied by building 1" lift engine mounts.

And probably the biggest headach to take care of. The lower control arms contact the bottom of the frame at about 4" of uptravel. Looks like I will have to do some notching.
Ride height

Contact

I also have some slight front fender well contact at about 4" with the steering wheel cranked. I cant move the axle back anymore without hitting there. Looks like a little cutting and sheet metal patching here. Hopefully I wont have to relocate the battery.

So thats where Im at. Need to do the mods above, weld on rear stiffeners, weld on the boat sides, make the exo cage (tube arrives thursday), make front and rear coilover body side mounts, convert my AC to onboard air, convert my OX to air, run airlines to OX and ARB, and of course other misc stuff that comes up.

question:
You running your 3 link?
Would others run into frame contact on up travel?
Why not do the inner fender panels like
http://www.tntcustoms.com/Jeep_Chero...er_Panels.aspx ?
With an optima like they show could still keep stockish location.
Just wondering.
Looks great! I'm glad to see you building this rig!

Yes, our 3 link. My LCA axle mounts are up higher than stock, so that brings my arms up as well; making them closer to the frame. Most guys on 4" of lift also arent trying to get 6" of up travel. I have a guy running our kit at 3-1/2" of lift and heas never complained.
I dont think I need to cut out that much inner fender but we will see. Thanks for the link and the ideas.
As far as the lower control arms go. I think Im going to put a slight bend in them for clearance. Way easier than trimming the frame.

Got the passenger side boat side notched out and tacked into place. Misjudged some of the needed clearancing to make them fit. Driver side will go smoother. Im still trying to decide if it would be worth trying to seal them up or just put some drainage holes in the bottom of the boat sides like the frame rails have. Thoughts?
