came home today to a nice big box sitting in the garage... return address... Sky Manufacturing... brackets are pretty beefy, made of 3/16" and 1/4" lazer cut steel. the front crossmember is CNC bent. the only thing, mine doesnt have the "Sky's Offroad Design" logo cut into it like most others do. not 100% sure that that's standard with this kit, although Sky did tell me at one point that it was optional. i believe it was 15.00 extra if it wasnt on there, but i could be wrong. the shackles are 3/8" CNC bent pieces, 4.25" center to center. the kit appears to be pretty much bolt on, with slots in the front crossmember that bolt to the area where the stock tow hooks go for adjustability, and 4 bolt holes on the rear hanger. i plan on bolting mine together, loading the rolling chassis onto a trailer, and taking it to work and buzzing it together with one of the industrial welders. checking the measurements the hangers are just a bit off of the 32.5" spring spacing,. the outside tabs are spaced about right, but the inner tabs are a little on the narrow side, nothing a couple washers wont fix, and should make the kit usable in Chevy Ford and Dodge axles.
