2009 Kenworth W900L AG400 8 bag ROUGH RIDE

This is a good point....I had a '97 one time with AG200 and it started to ride like crap and kill my back....put new cab shocks on....rode like a new truck. To the starter of this thread, Im sorry to hear about your ride problems, my new Kenworth has AG400 and it ride and drives like a dream...good luck and I hope you find the problem.

 

Nodoubt we're doing the same thing right now trying to figure out why this truck rides so rough so rough. the hell with the coffee cups and that's my teeth right out of my mouth

 

On an aerocab with a sleeper, the sleeper shocks do a lot to smooth out the ride. If you have a sleeper I would definitely change the shocks on it. Have a case of cold beer nearby.
