They are rebuild-able for racing applications. Otherwise they recommend every decade, or yearly for a motor over 800-ish horsepower from what I remember. Most bracket racers rebuild their motors at least yearly at the beginning of the season and the balancer rebuild is part of the process. The engine builder I worked at in my teenage years rebuilt these on every motor every year. It is especially critical on externally balanced and blueprinted motors. Anyway, this is another reason why a powerbond balancer is most appropriate for a street build. They are a bit over-kill and come with their own set of issues, such as needing rebuilds.

They sell the rebuild kits for them. You are essentially replacing the internal rubber and rings. It looks like it would be under a $100 to rebuild it.
