just a note, if you are going to run tall tires, and want to run the truck lower than stock you will need to move the the trailing arms back about 1.5" and change the angle on the rear axle. adding some 4" channel between the trailing arm front bracket and the crossmember (moves the rear axle back 1.5".) when you reinstall the front brackets rotate them 180 degrees. (changes the angularity of the driveline)
