I put about 2000 lbs on the front to see how far the front would settle ... Went down about 4" shackles came back . Once the build is on the road should settle a 1 below that ... should be in the 7" to 8" range .
I just got the inter frame rails prefitted and painted yesterday , going to get them mounted up and then I will get rear suspension on , I'm going with the DYI shackle flip and a set of superlift springs .
Then I can paint the whole underside of the body with POR 15 ... This body is like new and wanted to keep it rust free , the por 15 stuff is great .
Then I can drop in the motor ...
