Installing the 2wd Mcgaughys lowering in my 4x4 2005 rumble bee. The kit says it's only for 2wds but many have used it on 4x4s as we'll with little to no issues. The rear consist of sitting the rearend on the leafs and the front actually comes with new spindles. The spindles on the front is the only place where some have issues. Some times grinding is need for clearance. Most of the time with the 05 nothing is needed.
