Ultimate Advantage Shocks
To fellow U/A owners:
The shocks on our U/A are Bilsteins and currently ave about 52,000 miles on them. I am assuming that it is time to renew them and am considering Koni's. My basis for considering replacement is we are starting to experience some porpoising on rough roads and 2nd reason is the 52,000 miles on them.
Anyone have any experience with replacing the shocks?
What did you replace with?
How can you be sure the olds ones need replacing?
Thanks KIX

Don't know about your RV and Chassis, but a number of us UFO owners have replaced the Bilsteins with Koni's and the porpoiseing was cured.

We just installed Konis and are very pleased.
Safe T Plus, Konis, airbag control valves all made a very big improvement in ride.

Shocks do fail, however, it would seem rare that they would fail with only 50K miles. Have you had the coach weighed to ensure you are not over weight on a wheel or axle? Per chance your speedometer is not reading correctly and you're traveling much to fast for the road. (just kidding)

Hi Roadking,
We've not been able to have a 4 corner weight done yet. But, the weight per axle is well within the axle ratings. Actually I am not positive that my shocks are worn out. I'm only basing my thought on the bounce the coach does on some rough highways. It could be that the bounce is a feature of the air springs, I'm just not sure. Anyway, thanks for your response.

I am beginning to think the problem is related to ride height. Will check that when I can find a level concrete surface to work on.

KIX;
after you check ride height, if you have not already done so, add a set of the Motion Control Valves and you will be impressed with the improvement.

Kix- we travel to Baja each year, very rough & chattery road surface. We wore out Bilstiens in 10-12,000 such that the front end had significantly higher porpoising. The shocks weren't shot, just not capable of damping the big dips anymore. If you got 52K out of Bilsteins and were happy w/them, you'll save a coupla bucks going Bilstein again, and I predict will be happy w/the bounce control. I bought Koni FSDs for the chattery road, haven't tried them out yet so no opinion on that.

Thanks guys.
I've been reading about the Motion Control Units from Henderson Lineup. They are on my wish list.
