379 Low Air Leaf Height

Hey guys, new here.. I have done my research but am looking for a little more information. I have a 98 379 with low air leaf suspension. My ride height was set at 6.5" from bottom of frame to center of axle. Rear sagged a bit before especially when loaded and was pretty bouncy. I raised it to 8.5" which is what i have found others are saying, is this right? Seems a bit stiff but also seems to ride better at highway speeds. i have 22.5s on it and top of tire is about 1-2" higher then top of frame. Is there another measurment I can use when setting ride height? Sorry for the long post, any information is greatly appreciated.

 

Excellent, thank you

 

Thanks Lone Ranger, Im gonna check that measurment and see how they compare.

 

I set ride height to 8.5", got a bad vibration. I lowered it to 8", the vibration got better but is still there.. When set at 6.5" it had no vibration, is it possible this thing is low low air leaf? How do i identify? The hanger says low air leaf and the bag is mounted under the frame.

 

called pete with vin and it is low air leaf. Just cant figure out why it would only not vibe at that height, could someone have changed pinion angles to lower it?

 

ps the vibe is at higher speeds under load
