Where is everyone #5

I may be mistaken, I believe ag380 is correspondent with lo air leaf and ag400l is correspondent with flexair suspension.

I think either would be a noteable improvement as far as ride quality over ag100. I am right there with you on a cutoff, I'll tell you what!

 

AG400, Pete lo air, and AG380 are all different animals.
AG 380 (KW) and Pete flex-aire are the only 2 that are identical.

 

My '99 had the AG200 when I bought it. It was a clunky, loose suspension. You could always feels slack when shifting or getting on/off the throttle, no matter how much you tried to feather it. Not to mention that I couldn't keep it together.

Night and day difference when I switched to AG400.

I drove one years ago that I believe was AG100 and it felt fine. Course the truck wasn't that old back then.

 

I tried to share a link to the ag400l and my limited technical abilities won't allow it. However it sure looks a lot like low air to me. I will find out for sure at some point as I am not spending anymore coin on my ag100

I'm not sure why Paccar named the ag400l as similarly as they did to the ag400. They are completely different.

 

My bad. I am not familiar with the AG400l at all.

 

Best I can do a shot of ag400l from heavy truck parts

 

Yea I learned something here too. I had no idea kw did that. I have converted several like @ShooterK2 did his. Better part of a day and some bleeding and your all good.

 

Ag200 and ag400 are the same except for the bars. 200 had the junk wishbone that you can install the 400 flat bars on to make it ag400. The ag100 is the first version of the 8 bag which in my opinion is the better of the 8 bags. The 100 uses the bigger air bags.
