109SG  (RD10375  Oscillating Slider)

Genuine Shimano Oscillating Slider (part #109SG) — this precision component tracks along the worm shaft groove, converting rotational energy into the linear back-and-forth spool movement essential for even line distribution. A worn or damaged oscillating slider produces erratic spool travel, uneven line lay, and compromised casting distance. Cross-references with Shimano part number RD10375. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
