Looks like you are pricing the 5 lug without booster. It seems like the Summit CPP price ($375) with free ship beats the SSBC. One has hoses other has the pads. Hoses are more expensive. Both have cast iron GM calipers and probably do not include the slotted rotors shown. Both seem to include the roller bearings which you need.
POL has more stuff included, cheaper price and free ship:

I have found many times that these "trusted" type vendors have good specials on EBAY.
I AM NOT SAYING THIS LINK IS TO A PRODUCT THAT FITS YOUR TRUCK. That's up to you.

Some people have trouble with wheels fitting these kits. I have not have any trouble. You can easily and safely grind off the caliper sometimes. If you have a 16" or larger wheel you will probably be OK. Many 15" will work. But they do warn you in the literature/ads.
