10KZT  (TGT0566  Drag Washer B)

Genuine Shimano Tiagra drag washer B (part #TGT0566, SKU 10KZT) — a high-performance friction washer in the Tiagra's multi-disc lever drag system. This washer works alongside other drag washers in the stack to deliver the smooth, progressive drag pressure needed for battling marlin, tuna, and other big game species. When drag washers wear, glaze, or become saturated with old grease, drag output becomes inconsistent, generating heat spikes and jerky pressure that can break light leaders or pull hooks. Cross-references with Shimano part number TGT0566. OEM replacement ensures your Tiagra's drag stack delivers maximum stopping power.
