I installed the Centramatic wheel balancing assemblies on my 2006 model year classic. All that is required is to remove the wheel, place the Centramatic assembly over the lug studs, and reinstall the wheel on the axel. Technical details are:
Model year: 2006 Classic
Length: 30 feet
Rims: 15x6 six lug aluminum wheels as supplied by Airstream (5.5 inch dia. bolt circle)
Axels: Dexter
Brakes: Dexter hydraulic disc brakes
Centramatic part number: 200221SPECIAL (The word SPECIAL is important in the part number)
Centramatic contact: Jerry Robertson
We have not yet used the trailer since the installation. Now for a question. How am I going to tell if the Centramatic balancing assemblies have improved the ride? Can someone suggest what to look for?
In my case, I noticed the placemats on the dinette table rarely moved around. I also noticed a bit less movement of items within the RV. I'm not sure how much improvement they deliver, but I firmly believe that there is some benefit as truckers usually don't waste money on snake oil type gimmicks and many truckers use these. Anything to soften the ride is a good thing IMHO. Eventually I may also get an air hitch too.
I have put Centramatics on a pickup truck and a set of balancing beads in another vehicle. Both had similar effects - less vibration at cruising speeds above 55 mph.

We've used ours since '04 and after time one indicator might be in observing tire wear. The fact that I saw so many truckers at the manufacturing plant when I purchased ours was almost enough for me.
