A frac sleeve system includes a well casing with a tubular wall having a frac port defined therethrough for hydraulic fracturing. A sleeve within the well casing includes a sleeve body. The sleeve is mounted for axial movement relative to the tubular wall of the well casing among three positions including: a closed position in which the sleeve body blocks the frac port, a frac position in which the sleeve body clears the frac port so the frac port is open for hydraulic fracturing therethrough, and a production position in which the sleeve at least partially blocks the frac port.
