10G28 (TT 0311  Main Shaft)

Genuine Shimano main shaft (part #TT0311, SKU 10G28) — the central shaft in your Shimano Trinidad conventional reel that supports the spool and connects the drag system to the gear train. The main shaft is the backbone of your reel's mechanical system, bearing rotational forces from every cast and retrieve. A bent, worn, or corroded main shaft causes spool wobble, drag inconsistency, and increased friction that robs cranking power. Cross-references with Shimano part number TT0311. OEM replacement ensures perfect concentricity, proper bearing fit, and smooth spool rotation.
