109SA (RD8619  Oscillating Slider)

Genuine Shimano Oscillating Slider (part #109SA) — this precision-machined component rides along the worm shaft and connects to the spool shaft, translating the worm shaft's rotation into the smooth up-and-down spool movement that distributes line evenly. A worn oscillating slider causes erratic spool travel, bunched line, and poor casting performance. Cross-references with Shimano part number RD8619. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
