Thank you everyone for the valuable feedback. I didn't realize sway bar bushings were a big problem in more then just Kenworths, but we can absolutely make them for any truck. As far as exhaust bushings, and steering column trim, we will look into making those as well. You were all a big help.
Kenworth parts are pretty dear and rare especially in australia, ive never owned a truck in the US but used to drive for some private employers and they used to get really stressed out with their trucks
I have driven plenty of kw’s and really never had issues. There was an incident with a couple of the 2014 kw t800’s where coolant was getting into the fuel somehow. I drove them on rough roads in the oil fields and over the road. They are mostly made for rugged terrain. Frame is reinforced out of manufacturing for just that. I’m actually about to buy one myself.
