The PMF traction blocks are 1.5". For the rear suspension I removed the top and bottom overloads along with shortest leaf. If I let the air out of my bags the truck will lower another 3". For ride control I installed a leveling valve that's used on the rear suspension of medium/heavy duty trucks. As the truck sits right now I can have 6000lbs of pin weight and the truck will still ride level. The lights are just par 36 led work lights that I mounted in a piece of aluminum.
