I wouldn't think so. But mine is balanced to 4k.Would you benefit from this product if your motor is already balanced?

Yup! I have a DT466 from the early 80's, and it has one too.A good damper will help any engine, stock or otherwise. Reguardless of whether the engine has been balanced or not you will still have vibrations due to harmonics among other things. Fluid filled dampers have been used on high horsepower engines for years. Cummins and Detroit have been using them for 40+ years. They work.
