10LBC (BNT1743  Key Washer E)

Genuine Shimano Key Washer E (part #10LBC, BNT1743) — this keyed washer sits within the drag stack assembly, providing anti-rotation alignment so the drag washers maintain their proper orientation under load. If a key washer becomes worn, bent, or damaged, the drag washers may slip or rotate freely, causing inconsistent drag pressure and unpredictable line release. Cross-references with Shimano part numbers 10LBC and BNT1743. OEM replacement ensures perfect fit and factory performance.
