Make sure it's a spindle kit for a 3/4 ton and up 8 lug truck. They may have since I helped him look but no one made one 5-6 years ago.
What I liked about the spindle lifts were that it was easy lift and didn't mess with the steering or factory suspension geometry. He started down this road after we helped a friend lift his shortbox C1500. 3" spindle lift, some 32's and flashy rims, some stock Bilstein shocks, and a long AAL in the rear and his truck did everything he wanted to. He wasn't beating on it like a prerunner so he didn't need the full Fabtech lift or the compromises it brings with it.
