    I just bought a 2002 Kenworth T800. I was told the suspension was upgraded from the AG100 To the AG200. I was wondering what the proper ride height for the suspension is. Frame to center of axle is?????

    Next issue; the truck is a grapple truck with a lot of overhang past the rear axle. I am worried that the drive train angle is off due to the overhang. I had to put a lot of work into the u joints and input/output pinion shafts and bearings on the power divider. The height control valves are on the rear axle. Should I be concerned that the forward drive axle is too low affecting drive shaft angle. It is a little lower than the rear; not much but noticeable.


    Thanks In Advance,
    Jake

    The nice thing about a Kw suspension is that ride ht. is not so important to them. Drive shaft angles remain the same at differant heights. That being said I am not sure what the actual measurment is supposed to be the bars that run from the center out to the axle housing should be level with the ground. I would call a dealer with the last 6 and they should be able to tell you the specs. I would think it would have the same specs now as it did with the older suspension.

    Very true and probably the best advice, but here's another method I've found that works for me is to measure the frame at the front axle and then adjust air ride to read the same at drives.

    here I use to calibrate ECAS ride hight only by one parameter - truck with box height - 4.0-4.05 m....

    And that would be acceptable if all trucks were set up the same. Some trucks are built with a higher 5th wheel height to pull a float or other specialized trailer and that's when unfortunately your methodology does not work.

    Great thought though.

    Yeah, I know, but usually these trucks tow dump trailers ore tankers. so I do ajustment to get frame horizontal.

    I think the differance between the AG 100 and the 200 is the center stand that the sway bars attach to is made of aluminum(AG200) instead of steal(AG100). The steal were very bad about cracking. But then the bolts that hold the bars and bushings inplace were bad about corrosion.
