Here's the $550 axle. I'm happy with that. Hard to spend over $1000 for one when you will probably have to replace all the bearings, seals, gears, add an ARB, yoke, and possibly axle shafts. I've made up my mind, going to go with 6.17's. Also got the compressor installed, hey it looks like it's suppose to be there. Actually the bracket came off an old small block and since the V6 is basically the same, it fit, just had to cut an ear off, and drill a couple of holes is all. I plumbed the intake to the under side of the air cleaner, that K&N should work fine for a filter. The pressure side is plumbed to the center upright frame tube, then I drilled the main frame rails to carry the air rearward, and various other bars to act as an air tank. 1/4" holes thru joints, and welded up the outside holes. Got lucky, only had one leak, and it was in the middle of a tube, so I assume the factory weld missed a spot. Unfortunately it was behind the firewall which had to be ground loose in a spot to fix it. The tube where it leaked is also where I added to the cage height, so it is double walled there, one tube inside another, so I'm not worried about strength issues. For a total of 52 feet of pipe pressurized, that gives me a 4 gallon air tank, and one that's free and takes up no room. I figure I will run it at about 150 psi and use a regulator I have to cut it down for the ARB. I installed air fittings at each side just above the batteries, and will be putting in water drains at the lowest points also just in case. I did install a quick disconnect for the air cleaner housing and also the pressure hose off the compressor. So if for any reason I spring a leak, I can still get air from the compressor and bypass the tank. Trying to think ahead and avoid problems. Oh, by the way, the axle is out of a Dodge also. Mopar all the way!
