PJ, great question....
Eibach stocked nothing between 700 & 800 lbs. So thinking that the 700 pound spring would be too soft, I went with the 800 pound model. The spring preload is about 1.25" on the shock body. For a "2.5 inch I.D." spring, there must be another manufacture out there that would stock a 750lb/2.5" spring. The other adjustment is the shock nitrogen preload. I considered going with a "dual rate"spring setup, may still give it a try. Springs are cheap.
Right now with this coilover mod, the front suspension has gained 1.5" of additional travel. I had been having interference issues with the 31 inch tires rubbing the inner fenderwell, currently that problem is solved. So currently after some 5kmi on the suspension lift with these coilovers, I would say that they must be some more adjustment to make the ride a little bit softer. However, not wanting to loose much travel, I am considering adjusting (lowering) the shock preload pressure. Other that that, a winch & a pre-runner style front bumper will weight it down. Which is really the next step now that the coilover modification has proven itself out and the "cement truck" style of ride quality is gone. Getting ready to fab up some longer A arms. But sourcing longer axles are the issues here. There have been roomers of some longer china junk axles. I like to go fast, an old desert racer.
Planning on hauling the Ranger to Durango for some off roading in the very near future. Just an axle dolly pulled behind the F150. I believe that keeping the yellow sub level 2 as stock as possible maybe what happens in the long run, and pickup a 2wd and go crazy with it. The 4wd ones are around. I see them often.
