The dually 14s are 64" wide,came in cab&chassis chevy trucks, FF, 8 lug, 1 1/2" shafts w/ 30 splines. lowest gears I found were 5.13 but their could be lower ones. Open, Detroit or welded are your diff chooses. Very big and heavy, If you not using 38"+ tires the diff hang to low But you can shave more then an inch off the bottom.

I don't know but could be. I'm using a 14 out of a 1 1/2 ton rated tow truck.

If you swap to disc, you'll save about 80lbs in unsprung weight .

pyro, are you sure your's is 64"? you were the first one i had ever heard of this rear end and i remember you saying it was 62". after i heard this from you i went out and found one 62".

johnbuuu, look in cab and chassis dually chevy trucks (you know, flat beds, motor homes, box vans, wreckers, etc). they are the standard 8lug full floater. 5.13's is as low as they go. a 15" wheel will fit with no problems. i had to grind my front 60 calipers and brackets to fit the 15" rims though. not a problem because the calipers and brackets are very beefy and there is lots of material left.

From what I have heard, be carefull using anything larger than a dana 44 on an XJ. I have heard that the weight of a dana 60 or corp. 14 will rip the unibody due to the weight. make sure you reinforce frame rails.

i run a chevy dana 60 in the front of my cj. i already had the springs outboarded to hold my old scoutII dana44 and when i got the d60 the spring width was the same so i took 3.5" off of each side to make the 69" wide d60 62" wide to match the 14bolt. my scanner is jacked up so no pic's. i hope to be getting a dig camera soon though. well when you go looking for your 14bolt take a tape measure. and just measure them when you find them. if they still have wheels on the measure between the two weels on each side to between the wheels on the other side. in all my looking all 14bolts i found were 67" wide both single rear wheel and dually but the two cab and chassis versions i found had the 62" wide version. i had to search quite a few yards before i found one. i did find a few eaton rears that measure 62" wide and one dana60 but the d60 had the small shafts and 19 splines so i didn't use it. as for converting iot to single rear wheel all you reall have to do is slap the single whell on it. they bolt up the same. tthe lugs are longer. i swapped my lugs for ones made for the single rear wheel but other than that that was it. these rears are big and stout and should be the last you'll ever need. you will want to take a grinder to the bottom of the housing to "shave" it. this will help with some of the ground clearance issues.

high5 and i have known each other for a long time, and our jeeps have always been similar. my 14 bolt was $300 ... he knew it was the only one in the area...but it did have 4.56 gears and it is very nice shape.

pyro, i knew you had told me 62" wide. i got this from your web site.
This Corp. 14 bolt has 10.5" ring gear, 5.13 R&P ratio, 30 spline flanged axels. This is a very strong unit, comparable to the Dana 70. The Dually axel is a good choose for Jeeps and other narrow track vehicles because it is only 62" wide overall.

TSM caliper bracket and rotor(you can also use a front Ford rotor), GM(small) caliper and homemade bracket spacers. The backing plate on the dually's is farther and from the hub(WMS)then a single wheel axle, The TSM mount is for a single wheel axle so it needs to be spaced in for a caliper to line up with the rotor. After spacing it to the right spot, I also welded it to the axle.
