Sure, they will fit fine. The 4 inch backspace is the same measurement as a stock rally so that gives you an idea of how they look under the truck. The 4.5 inch backspace will tuck under the truck a bit better if you lower it.

Up front a 15x8 with a 4" bs. is the most backspace you will fit up front without having wheel issues. (wheel contacting the lower a-arm) You may even have to trim the lower a-arm with a grinder. Calipers sometimes need grinding also.
If you would go up too a larger (17"-20") diameter wheel, more backspacing can be used.
The rear should be fine with 15's and a 4"-4.5" bs.

Keith, I do not agree. I currently have 15x8 with 4.25 backspace on my truck lowered with spindles and springs. Nothing needed clearancing anywhere.
