Hi everyone,

PLAN B

I want to change my KW torsion bar rears to a single drive KW torsion bar set up, BUT ?

Has anyone had any experience with a swap like this or recommendations of whats good and whats not.?

The trucks a 1976 K125 with rear rockwells. I would like to keep the existing rear diff if thats possible in it current location on the frame.

Kenworth Australia don"t recall any single drives on torsion bar and have recently sent me the front hanger bracket diagram. This part they don't recall seeing here !! and not showing available either.

Apart from tailshaft mods etc, can anyone see any reason why you couldn't just use the existing set up leaving the adjusted front mounts as it is and just dropping out the front drive diff ?

Some of the pics in reply were helpful especially the single drive conventional John Woge posted, John did you take any others of the truck?
Any thought guys. Thanks

Geoff in Australia

Geoff, it should be pretty easy to change that to a single axle. you just need the rear axle off a twin screw. since you are not going to work it hard you won't need a 23000 axle. I would suggest staying with a low leaf like pete. if you find a volvo they have a nice low leaf as do a lot of others. it really is fairly easy. just get some factory drilled holes to match up with suspension brackets so you maintain alignment. keep us posted and we like pictures.

Yeh thanks Fuelem,

Been checking this site, great truck he's building, thought the 66' might have been finished.

Not easy working outside on something eh, specially in your winters.

Hi Wayne,

Yeh the KW won't be loaded up like she was original intended, want to pull a single axle drop deck for carrying a 6 ton boat and the occasional load of stone for my work.

The Peterbilt airleaf I like is a bit harder to find in Australia. Petes aren't that common here. A bolt up conversion would be a nice way to go, I don't really want to weld up unused holes either. The Reyco and Freightliner air bag rear hangers are quite well used here.

Will post some pics of the conversion when I get started on it, still ordering up interior parts at the moment.

..........love those Dayton wheels.  If it were up to me, I'd have them on everything.  BUT, I realize that I'm in a minority here, SO, to each his own.

I just had to say that.

Yeh Hi, scsiguy,

Thanks,I love these wheels too, and plan on keeping them, when I do the single drive conversion ( Lot of Aussie trucks still use them,  call em spiders here)

Just got some nice new KW logo baby moons to fit to the centres for the steers.

Plan on painting the spokes gold and exchanging the rims for chrome ones, with 5 SS nut  covers.

Should look nice when done.

http://forums.aths.org/InstantForum2010/Uploads/Images/c284faf9-e29a-41a8-9cd1-da04.JPGI'm customizing a GMC bus air suspension onto a Rockwell rear end. It has Dayton wheels and will go under a fire truck. In the attached picture the GMC air beam is on top because the rear end is upside down. Easier for measuring. The brake chamber mounts to the air beam. There will be a rear sway bar. The sway bar links connect to the air beam.

Fred I like the Daytons also. There are a few of us out there. Probably a lot more in the closet. You know "Don't ask don't tell" Joe D.
