When, & cost, to change shock absorbers?

This is a public forum to discuss Eagle related technical issues. If you are having a problem with your Eagle, this is the place to find help.


Hi, I'm a newbie to Eagles (1979 Model 05 converted in about 1997), so lots of questions over the next few weeks. here's the first:

How do you know when your Eagle needs new shock sborbers?

The reason I am asking is that I recently did a 1200 mile trip in which the bus suspension felt just fine (satisfyingly more firm that the typical airbag motorhome suspension we had been used to :) ). But, on certain bumps, particularly those found on elevated overpasses in East Texas ( :) ), there seemed to be way more "hobby horsing" than I experience in a car or that I recall experiencing in our previous National Tradewinds pusher.

I have been warned more than once that the combination of the Eagle's tag axle being in front of the drive axle, and the torsion bar based suspension's conversion of suspension movement into fore and aft versus sideways displacement, craetes a hobby horse type of effect on some bumps. In fact, I've been told that the driver can start to "defy gravity" if the seat belt is not on tight!

But, I what I am wondering is, on a stiff bump at 65 to 73 mph range (depending on speed limit at the time), does an Eagle with decent shock absorbers bounce more than once or twice?

I've only ever experienced this hobby horse effect on elevated overpasses, so I'm wondering if it's just due to the bus's front end trying to go airborne, or if new shock absorbers would make a bbig difference.

Also, if and when new shock absorbers are required, how much do they cost for parts and how much for instalaltion typically?

Jim,

I would install the double action Gabriel shocks on the front end. The Gabriel no. is 85-314. This will stop make a big difference on what I call the porpoise effect. The bogie and the drives use Gabriel no. 85-303. Both of these shocks are about $45.00 each and should take only a couple of hours to install assuming everything comes apart easily.

Gentlemen, You can now post part and part numbers in the Sticky Thread at the top of this area, Eagle Tech.

Daniel, your information with reference to Gabriel shock absorber part numbers got me worried :roll:

Later in the conversion process of my Eagle, I learned how to align the suspension from Gerry Meeks at his residence in Vista, California. He owned two Eagles and had all the appropriate tools. He also recommended replacing the shocks on my Eagle with “Gabriel-equivalent” gas shocks. So, we went ahead and installed Road Leveler K374-28 (Manufactured by ARVIN RIDE CONTROL PRODUCTS, Inc -- Toronto, Ont., CANADA M8W 1N6) on both front and rear axles. Unfortunately, Gerry passed away some time ago and I have not been able to obtain additional information.

This leads me to my question:

Are you -- or anyone else on this board -- familiar with the Road Leveler K374-28 gas shock absorbers? Did I commit a serious faux pas (to say it mildly) by installing the wrong shocks?

Chris,

I am not familiar with the Road Leveler K374-28. There are many equivalent shocks to the 85-314 & 85-303. If the Road Leveler shocks are working for you, then great, leave them on. Eagle coaches were all originally equipped with the 85-303 shocks. In the late 80's they changed the front shocks to the double action 85-314 shock. I believe they made the change when the 45 foot Eagles were introduced. I know of one person who runs the 85-314 double action shocks on all axles and he tells me he gets more compliments on the ride, stability and handling of his Eagle then he ever has before.

Daniel: You are a reliable source of info on our Eagles! Could you have a look at that torque converter stall speed posting I placed yesterday?
