If you can use an oem generic replacement just extra stress on bearings.Replacement parts are only warrantied to last 12,000 miles, but many are nearly as good as new build.
The point was the engines were built to last 500,000 miles if you changed oil every 90 days.
You can install weights from old pulley in correct holes on new pulley and accomplish a very near match.
