10KM5 (RD9840  Line Roller)

Genuine Shimano Line Roller (part #10KM5) — this roller sits on the bail arm and guides your fishing line onto the spool during retrieval, spinning freely to minimize line twist and reduce friction. A worn, grooved, or seized line roller is one of the most common causes of severe line twist, premature line wear, and reduced casting performance. Cross-references with Shimano part number RD9840. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
