    I have a 1986 W900 day cab, had a big cam 3 with neway suspension. Its stripped down pretty far and Kenworth is less than helpful as they dont have much info for that old of a truck. For starters im looking for suspension ride height and suspension torq arm lengths. Any info would be much appreciated!

    Have you tried calling around to different dealers? Could be they don’t want to dig for the info or they don’t know how.
    @AModelCat may know of some places to check.
     
    Tug Toy and AModelCat Thank this.

    Looks like PSM379 has the whole deal for you.
    Where I worked at they were most all trailers with Neway and a leveling valve for each side. They could be a struggle at times. Adjust all perfect in the shop and drive around the building and back in the shop. Then it lean to one side. Adjust it again and repeat. Leans the other way.
    Drive around one direction and check it. Then drive around the other way and recheck it. Stop do so much adjusting and run it. If it overall leans one way most often adjust one of the valves to compensate while trying to maintain the air bag height you desire.
    Many tried to convert them to a single valve system as others but they always ended up back to the valve on each side system.
    When they work correctly they can save your butt. I dropped in a curve on a construction clover leaf. Trailer was leaning left badly. I was afraid to speed up or slow down. Maybe slowed down just a bit off throttle. I thank that Neway dropping air out of the right and adding air to the left kept it from rolling.
    All driver skill for sure? That was a thank you Jesus moment!
