I have some 2-3" rough country front springs but I don't know if they will lift your 1 ton 2.5-3" over stock. They are in good shape. My one ton sits a good 2" taller than my 3/4ton out of the box so you maybe talking 4" springs. I would use an ORD flip or blocks in the rear.
I also have a center console from a early '90'2 K5 blazer if interested.
