||827 Anti Vibration Ring
A nylon ring that is designed to hold the radials much tighter than is possible with the standard arrangement - and is HIGHLY RECOMMENDED!
We have an 827 here, and have one of these rings fitted and have not experienced any of the "low pitched howl" in the wind that some 827 owners have complained of.
There are two nuts and bolts for every radial and it really does hold the whole assembly together much better, so it's a must for those windy locations.
