[Dyno]

I have been at Fastshocks when all brands, specifically Afco, Koni, Penske were disassembled for rebuilding. Shock oil and seals go skunky after time, some sooner than others. Unless there is mechanical breakage, a shock slowly wears out, and you may not notice a drop in performance. I believe road miles are harder on the shocks than racing. A service on your shocks, especially this time of year, is as important as any other aspect of your updates and maintenance. For most racers, it may not be needed every year, but something to consider. Dyno.
