What's this cylinder for?

[amphi_sc]

Looking under my coach at the rear I see this oily cylinder next to the shocks.  I have only air leveling - no hydraulic jacks.  So what's the function of this cylinder and where might a replacement be found?  Does it have anything to do with sport vs comfort mode on the driver's console switch?

Thats a shock absorber that needs to be replaced.  Do at least all 4 on that one axle.

I would plan on doing all at once (all axles) if you don't know when they were last replaced.

It's time and it will drive much better.  Look at Koni then Bilstein.

So do I have 6 shocks on that one axle? Three per side?  The other two longer ones look different.

Maybe a shock? Or, if they are on the TAG AXLE, the “lifting cylinder” or where you adjust the Tag Axle.  They are usually air, so maybe not.

One picture is the “yellow” Bilstein at the top of top of the “thingie”.  
 

There are 2 Shocks per corner plus one on each side of the TAG.

Consult your owner’s manual for a description of the “comfort” switch.  That’s a new term or switch to me.

4 on the drive axle, 2 on the tag axle.

Yes, I read air only but some Beavers had hydraulic leveling… cylinders between the rails and the axles. Definitely not part of the Sport shocks which are electrical controlled.

The electrical connection on the top and short size threw me off compared to the other more typical shocks.

By the way, owner's manual has no description of the dash switch.

Many Beavers have air and Hydraulic leveling. It's an option that was very popular. 

Your coach manuals are available on line.    

ADJUSTABLE SHOCK SYSTEM $2,754.00  was an option in 07 on your coach.

Get the build sheet for your coach.

May be easier to think about it like this... every air bag will have a shock. 

 

My Roadmaster has 10 bags and ten shocks. I just changed all the bags and all the shocks and the coach handles like a dream.
