You guys have been so helpful, and I really appreciate it. Although we have a reliable mechanic, it does get expensive to have him do every little thing, and we want to start doing some of the maintenance items ourselves. Hence our asking all these questions.
Our 80 Eagle does have a good bit of "porpoise" and although we know this is inherent in an Eagle, we would like to know if there is a way to minimize it. We feel like our torsilators (sp?) are good. If you lay a yardstick level from the edge of the wheel well aluminum flare, it will measure a little more than 6 inches down to the top of the tire. This is pretty much all the way around the bus. We have some friends with an Eagle much like ours who just had theirs indexed and their clearance is about the same.
Somewhere, we read that there was some type of shock that would minimize the porpoising, but we can't find that info. We had new shocks installed on the front the first of last year, but our mechanic just used a Gabriel shock that was similar to what was on the bus, and we are not sure they are adequate.
We are not suffering any "bottoming out", but it will "buck you" in the driver seat a little more than I like.
Thanks for your help. |

These are probably the best out there and the price of these aren't cheap.
Koni shocks part #90-1898 Adjustable
I have them on the front of my 85 Eagle 10 and they really made a difference. |

I put Gabriel ADJUSTABLE air shocks all around on my 80 Eagle and it got rid of all the porpoising. Adjusted for maximum. One of the best investments I ever made on the Eagle. Might want to check with Dave at Southern Oregon Diesel. He is the one that turned me on the them and then actually installed them for me.

Richard,on some Eagles that shock may work good SOD installed them on my Eagle and i had to remove them and install different one because that shock is a single action and you need a double action on the front David Anderson use them on his Eagle and has good luck Sonny Gray uses the same shock on his Eagle as i do |

I believe both Sonny and David got their shock information from me. Maybe it was not Gabriel. Too long, do not remember now exactly. I know I talked to both Sonny and David about it.

Richard you are correct the Gabriel shocks are 89-425 Adjustable and the Monroe shocks are E-MN74025 but they are really weak weak compared to the Koni's that I put on my Eagle. The Koni's I had to take a pry bar to extend them and the others I extended by just pulling by hand. |

I have had good luck with the Koni as well.
I always tell folks the best way to minimize the "porpoising" is to look for dark spots in the center of the lane. When you see those spots slow down, they will almost always cause porpoising. The darker the spot the harder it will be. Anyone else notice this?
In my millions of miles driving entertainer coaches I have found this to be true 99% of the time.

I found the worst places to be the transition from concrete to blacktop on the many overpasses in the CA freeway system. Unfortunately you can not always see these in advance and I have had a few that actually raised me out of my seat.
Of course, that was before I changed to the adjustable air shocks. After that, not a problem of any kind.
