An interesting read, of an engineer's test report as per Australian Design Rules, about an HDJ-80 modified with 44" tyres:

WOW !! Quiet a report man! What amazes me is that people can build a truck like that with regulations. Why can't we

That is one bad, cool, awesome looking cruiser.

What's stopping you? If you want one, get out the sawsall, welder and a stack of $$$!

Steel body spacers? Sounds like you'd get a lot of cabin vibration that way.

I would imagine some kind of washer or other way of dampening it would be used, since they tested it for sound and everything. It does sound a little rough, nylon would be my route..

If they did a 100mm body lift by addiing 100mm steel blocks, then they must have either reused the original spacers or used something in addition to the steel blocks, Otherwise, it would have been less than 100mm of lift.

That thing is awesome .At the moment it sits outside Fourby's tyres at Moorooka in QLD . I was talking to one of the workers there last year when I was getting new tyres fitted. I asked how it handled being so high. He said it drove like a sports car. The sway bars are fitted with hydralic rams fed by a pump under the bonnet that has a switch that works from a pendlum type set up. The more body leam the more fluid pumped. Said it was like a tilt train that leans into the corners.

The body list is not done in the way most people do it with pucks and longer bolts. All factory body mounts on the frame are relocated 100mm up and the original body mount bushings are used.

Riad, nothing is stopping anyone to build that except $'s. We have had quite a few requests to do so, but people don't want to put their $'s behind it. When we met with Artic Trucks at Sema we discussed their buildup etc etc. They have more than 100 hours in shop time in just the body relocation, axle relocation and body work into the trucks. All is pretty easy to do, just a tremendous amount of time.

Christo, Obviously money and time are two major factors. My concern is more pertaining towards regulations and laws. For example, if you drive a truck with 44s on in MD, as a daily driver,you will need some major inspection done or you are bound to be pulled over and given ticket(s). Ofcourse you could put on 35s and extra plastic front and rear ends to make look like low enough to the ground. Therefore, my point is, you spent the money and time to build the rig and then you MAY/WILL have to spend more time and money for the local government to make such rig legal for road/daily use. I am sure you have had few requests to build such truck, what I don't know is it would be legal in all 50 states. Whereas in some other countries (Like AUS) there are vendors/shops that are legally approved by local/state government to build trucks like these. AND last, but NOT the least, we don't have Slee and or MAF type shops every where . One of these days when I have 30 or 40 grand stashed up, I will make a trip to CO and have you build some thing like this

For the time and money, I think I'd rather go with a Mattracks upgrade than go with a well-engineered 44" tyre setup. Like this: http://www.oman4x4.com/vmattrackstlc.htm . It seems so much better on sand and mud, and maybe even snow, that I wonder why the Artic Trucks people went with 44" tyres?

That 80 is pretty old news .. in one shot from that link there was a vehicle with an aluminum bumper like a TJM. Was it the same 80? Can you get TJM bumpers for the 80 that are closer in style to the ones available for the 100?



TY

From where I am, the answer is yes. There in USA, I dunno.

Decent tech write-up.

Well I'll be damned. I saw that sucker in person back in 99. I was in Oz for 7 months, and was in a small town near Byron Bay getting my car registered. I saw him up ahead of me and followed him for a few km. That thing is AWESOME in person!
