AMT Movin On Kenworth Announced


Recommended Posts

Can't imagine it being the Torsion Bar version, they were only ever available on the first W Model, plus the cab over and the Challenger cement mixer. The torsion bar suspension was such a nightmare to construct that AMT pretty smartly dumped the idea and replaced it with the Hendrickson suspension.

One can wonder why AMT went to the Walking Beam when they dropped the Torsion Bar.
Kenworth had other suspensions to choose from other than the Torsion Bar and Walking Beam, they also had the 4-bag Dual Air Spring and the Big Six Six-Rod Leaf Spring for the dual drive, they also had the Page & Page and Monkey Motion suspension for the single drive with push or pull axle.

I'd figure its just due to ease of casting. Walking beams are pretty simple and the molds would be cheap to make as well.

The reason I wonder is that the first truck kit AMT did wich was the Peterbilt 359 "Small Window", and the 352 and the later 359 1100 cab all had a more complicated air ride suspensions, and the other truck kits from the same time period had other types of leaf spring suspensions...so I don't know if simplicity was a factor.
The Torsion Bar can be done a bit less complicated and easier to build too if you change the layout and parts a bit.
