Driver side ...loosen the two bolts...take out the 1st bolt (left bolt completely) then slide bracket to the ass end of the truck
Pass. Side..loosen the 2 bolts take out the right bolt completely side bracket towards front of truck.
While doing this you'll have to adjust in little incriments (spelling) to get the desired drop.
Also take off bump stops or cut them while on the truck (pita) or truck will stop dropping at 32.5 cuz of the bump stops hitting. (Plus terrible ride).
To lift the truck slide bracket in the opposite direction. Mine is at 32 from ground to fender. Sitting a little lower than front. Enjoy!!! (Well till I get my front lowering kit)
