I spent many hours of reading on PBB , tons of over-educated engineer speak
... but there was good info to be found.
My system will be a double triangulated 4-link with non-parallel bars.
The lower links will terminate on center-line of the diff , while the uppers will end almost touching on the rear truss with a length of 80% of the lowers.
Still kicking around the the adjustable rear truss , it will be that or the there will be adjusters on the rear of the upper tubes.
Also undecided on how the front of all four links will be mounted, ether vertically staggered or in line. From what I've gathered if they all move from a common vertical center-line there's much improved squat/anti-squat, but the risk of links contacting each other during there cycle is much greater.
Since this rig will still have a tag on it I will most likely incorporate a anti-rock sway bar into the rear set-up as well.
Also looking for info on springs, would like a choice other than F150/Bronco
4"-6" lift coils.
