07 crew cab 1/2 ton 2wd

some of the kits have springs/spindles/shackles/leafs/lower arms/etc..

which is gonna keep the best ride quality.

so far I'm leaning toward the Mcgauhy's kit with spindles and drop leafs. It seems the easiest to install. Please correct me if I'm wrong.

Also, I'd like to pay a pro to install in the Dallas area. Any suggestions???
