12" lift (all spring in rear, no block) and 42" Swampers, duals in the rear, so the thing is stable as h*ll!!! Figure that to fit 15" wide rear tires the offsets on the rims (custom 16.5"x9.75"s) have to be pretty wild, thus making the track width wider in the rear (106"!! Whoops!! Sorry California Highway Patrol!!!
) This rigs also tows fantastic, as you don't even know anything is back there!! I tow an 8500 pound boat, and when I do tow the boat with one of my Suburbans, it pushes me around quite a bit. Not so with this dually. The 5.13 gears help also.
