looks like a 4-6 drop kit but its hard to really guess. every truck has its own height characteristics, especially trucks like these. years of load can cause springs to compress down.

That's a 5/8 to get the valance that low to the ground. Tires are most likely 275/60's. They've likely cut out the fender lips for tire clearance and hidden it with those flares.

To each their own but I think it looks terrible. :( (mostly the flares)

Yea i dont like the flares either but the stance is nice.if you did a 4/6 on 15s what tire size would fill the wheel well like that

8" up front you want minimum 4.5" backspace, 5" would be better. 10" in rear you want 6" backspace. Not sure on that width of tire in back; haven't run it on a dropped truck. But any more than 6" backspacing would be tough to find on a 10" wheel and then you'd have to start worrying about interference on the backside. When you go low and wide you have to watch for interference from multiple points.

Offset is just a different way of measuring backspacing, so you can go with one or the other. Speaking in general terms, backspacing is often easier to understand.

What if i did 5inch backspace in the front and 6 inch backspace in the back with rolled fenders? Would i still have clearance issues?

That's exactly what I said.. 8" wheel in front you want 4.5" backspace minimum, 5" would be better. 10" wheel in back you want 6" backspace. I can't comment on the tire sizes because I haven't run 15's on a dropped truck. They will probably fit, though.
