This is the HT100 drag upgrade, which we feel is the best all around washer for ANY reel. It offers a smooth startup, good holding power, and because it is a carbon drag washer, will not heat up and fade like the original....eliminate line jerk when fighting fish! Any ?'s regarding fit, please either Contact Us or see our Schematics Pages Kit contains 3 drag washers. Please note: Shimano has redesigned the Spheros a few times now. We have noticed some come with only one drag washer, some with 3 (in the spool). If your reel has 3 stock drag washers then this is the kit for you! 56710x3
