well, I have the TR/Avalanche locks on mine but I have yet to wheel it:d so I cant tell ya how I lie them. The only reason I ended up getting one of the most expensive locks out was cause I got a KILLER deal on them if I were to do it again I would deffinitely get the DIY or the Allieds if I didn;t know how to weld or wasn;t confident in my welding. They(as of now) are not legal for on street use, I am pretty sure Scott from Rockstomper has checked into it quite extensively so you might want to check with him about the details of it...the bolt pattern of chevys and toys and Waggys is 6x5.5"...if you really plan to stick with those axles then I would say get them...if there is even a slight chance you may swap axles then I would wait on the locks...you dont want to get too little backspacing cause then you start to put un-needed stress on the wheel bearings...I would personally swap you outers to 8 lug stuff (if its possible, I'm sure it is since there is a milllion different types of 8 lug 44s) and then get 8 lug rims...that way if you do decide to swap to 1-ton axles or just fullwidth your rims are not an issue...plus if you ever have to sell them your market is a lot bigger with 8 lug stuff...goodluck
and BTW I think I have heard that 4WPW can balance any size of tire up to a 44" I believe...didn;t sky get his 40s balanced there??? I dunno
