    What would it take to replicate the dually rear wheels on a CJ5?
    Does anyone have pics of the parts needed?
    Are the wheels special for the dually option?

    The actual trencher dually has a narrowed Dana 60 rear axle, which accepts the dual six-lug disk-type wheels. I believe these are standard 16.5 truck wheels from the era. The front axle seems to always have the conventional axle with the 5 on 5.5" bolt pattern. There are a lot of pictures online - jeep trencher - Bing images - of examples with single rear wheels, dual CJ wheels (which I expect are bolt-on dual wheel adapters) and the real Dana 60 duallys. I expect the trencher could be installed on any CJ, and that's what a lot of them are. Pretty sure the real D60 dually came that way from the factory, on special order.

    hmm, would like to keep same bolt pattern. Was looking at making a CJ6 dually. Kind pick up-esque, looking to the CJ6 body, much like a CJ8, and then add duallies and a half cab. Before anyone cries foul, the CJ6 body is a total mess, not really a candidate for a nice restoration.

    do a search on 'Nelly Belle', the jeep that Pat Brady drives in the Roy Rogers show. She is shown with both dually and single wheels mounted on the rear. And the gizmo for mounting the outside pair is visible when they are not mounted.

    Yea, the trencher jeeps have the bigger dana axle with offset rims. I thought it was a dana 70 but tim might be right. All i know is it's big. The diff takes up most of the room between spring packs. They have the 2 piece ring that holds the tire on the rim. Think couple manufactures used them, but they are scarce. Ive got the dually on my plow jeep if you want any pics of it. It has 5.87 gears in the rear and 5.38 in front. They had 2 different tire sizes to make up for the difference

    Split rims? You may have trouble finding a tire shop that will change tires on those rims - they can be dangerous. The shop needs a cage to put the tire and wheel inside for first inflation. This prevents injury if the ring comes off when inflating. At the Jeep dealer, lacking a cage, they'd put the wheel under the hoist arms to trap the ring if it flies off.

    Also they are probably 16.5" diam, and few tires that size are available now. There was a recent thread on IFSJA that mentioned a Traction King (?) or Power King (?) 16.5 bias tire, and Firestone makes the Transforce HT in a couple of 16.5 sizes.

    Are split rims even allowed on the road anymore? I was looking at a '70 chevy PU a few years back that had them & was advised they were no longer legal, maybe it's a local thing.

    I don't know - in the USA, I doubt the authorities would force you to replace original equipment that was legal when it was sold ... but I would not be surprised if they stopped shops from servicing them on worker safety grounds. This would be a de facto ban for most owners.

    If the tire is of .5 size(14.5,16.5,17.5,19.5,22.5 etc) they are tubeless and never have had a split rim made for them. Split rims are always of the whole inch size(15,16,17,18 etc). Center split rims are illegal to run on the highway and you will be hard pressed to find a shop to service them. Split rims with a lock ring at the outer bead are dangerous also but not like a center split as you can see if the lock ring in seated in the groove. I turned every center split away back in my service shop days but worked on many of the outer bead split rims.

    Well I think I'm gonna ditch the dually idea on the CJ6. I was gonna swap my D44's from my CJ5 to th eCJ6, but gonna keep them on the CJ5. the CJ5 will be more of a trail jeep than a street Jeep. the CJ6 is gonna be the street Jeep, which is why my donor will have A/C. Gonna put a half cab on it, and extend the body longer to give it more of a truck bed look. I'll keep the YJ D30 and D365, and eventually swap in a Ford 8.8 to replace the D35.

    Shouldn't the rear axle of a CJ6 be a D-44, same as the CJ5?

    These are the outer bead lock, 16" rims. No half size. They where harder to break down than to put back on.

    Ive had thoughts of ditching the dual axle but that would be a couple years down the road

    From the factory, yes, but he says he has YJ axles in it currently.

    I'd love to stumble across one of those dually cj5 rears and the fender extension to match. Love a dually cj5.

    As for the split rims.......I'm not sure I understand the terminology as to center split rims but, I owned a 1971 F250 4x4 that had 16.5 tires and rims on it. The rims had the outer split rim/ring on them. First thing I did was ditch those wheels and tires in favor of later 16" solid rims.
