That kit looks like it includes the valve and linkage.................good find Stump.
I remember a while back some were concerned about the Contitech air bags having a plastic nest on the bottom vs Firestone with
metal. I have the Contitech and no problems yet with the plastic.

kn27000 valve will work but may not be the same as other others on our coach, best to replace both ride height control valves if not sure on your rear axle. You may be mixing a standard flow with immediate flow valve.

Stump : Since I have a 1990 GV I am following this with great interest. I see now there is standard flow, and also immediate flow. Any idea what we have and will changing the rear valves ( mixing one with the other ) affect handling and ride? Going to get a spare valve after Ted's experience and want to make sure I don't end up changing it on the side of the road only to find out I used the wrong one.

Thanks, Steve

Change all three and enjoy the ride. Changing only one in the rear could cause you to limp.

Well gosh T-Man there only 29 years old! What could go wrong ! In all seriousness that is an outstanding thought. At the ebay prices could do it for less than $150. However if I'm going to do it back to the original question. Normal flow or immediate flow? Anyone out there with experience with both?

Replaced my three valves with a Haldex immediate response from Finditparts.com
3 original ones after 20 plus years failed internally in the same manner.

Did you also order the kit linkage?
Why didn't you go with the KN27000?
On ebay, the seller says there is a difference between the 27000 kit and the 27000 valve??!!
Totally confused as to the different prices for the same ?? unit
Can someone set me straight?

We were in Nac at Foretravel for the ladies drivers class when mine went out. They replaced it. Should have bought some spares when I got home, its on the list. My thought is, after 20 years, best to replace all 3 and have a spare. They have a lifespan.

I guess we need to contact a good parts man that can steer us to a inexpensive (read China)
duplicate of what we now have using our OEM part numbers. I plan to buy three offshore replacements to carry as spares so I'll get on it in the morning.

Kicking back outside the coach now.

90555105 is a genuine part made by Haldex, price difference. The rest are knock-offs as I see. I carried a KN27000 and kit as a spare and used when needed but changed out because I wasn't satisfied with the operation of it, it's back in the spare parts bin.

Once again, do you also order the linkage kit??
Which one of the two shown?

These parts are commonplace on Freightliners
apparently. Although Freightliner ain't Peterbilt........ Freightliner ain't bad, and there are a lot of FL chassis' running the roads that run aftermarket parts that seem to work. No?

DOT airline fittings and not DOT ride height valves..........WTH?

Personally I wouldn't worry about the linkage kit nor have I seen it offered with the genuine part.

Never saw a Freightliner or any other truck or trailer running two ride height valves on one axle, these were designed to be center mounted like our front axles.

So the valves on the rear are different than the front one?

They are the same. I feel they take some excessive abuse being mounted where they are in the rear. The immediate response valve works for me especially mounted in the rear for cornering. Standard flow valve could be 4 seconds or more before it responds.

I'm confused now. I thought that you could replace all three valves with normal or intermediate.

OK, would someone who is in Nacogdoches run this by either James Triana at Foretravel or Aubery Lee at MOT.

The question: please tell us which style ride height valve is best for our coaches and WHY-- immediate/quick response or normal/slow response.

Inquiring minds want to know. Can see advantages/disadvantages to each.

My thinking is in the trucking world the standard flow valve would be more appropriate especially on a trailer or I don't see a problem with it on our front axle as much as the rear. I like the immediate response in the rear for sure, reacting immediately to any lean that you may encounter going into a corner. Why would you not want it to react immediately? It may use a little more air over time going down the road but hardly noticeable.

I'm here was delivering a tanker in a Amish Ohio and no service where I was. The valve I bought seems to be the same flow as the original.
If you buy this kit you will not use the linkages they are different for a semi-truck.
I bought it based on cost . Looks to be decent and lets air in and out loke its supposed too.

Brett- this may not be the full answer to your question but I called and talked with Aubry Lee to try and get a part number. I was told that they used different valves at different times, so the best thing to do is take off the one that is on the coach and match it. He said if he gave me a part number over the phone there was a chance it might not work.

Maybe someone else can find out more information, but that is what I was told.

Would still love to hear the rational for the choice.

And, am surprised that it would depend on model/model year (if we are talking about a U280, U300, U270, U295 or U320) since, with the exception of the very few with IFS suspensions all are virtually the same. Two ride height valves on rear axle, one in front.
