The dimensions are in inches for seal I.D. x seal O.D. x thickness."

The rest of the story is, you need a strong press to remove the press fit shaft from a shock absorber and to reassemble it. If the shaft is grooved or pitted the new seal may not last long, so the shaft may beed machining or may need a SpeedySleeve for repair.
