10JUU  (RD9975   Oscillating Slider Bushing)

Genuine Shimano Oscillating Slider Bushing (part #10JUU) — this bushing lines the oscillating slider, reducing friction as it travels along the worm shaft and ensuring smooth, consistent spool movement for even line lay. A worn slider bushing introduces slop and hesitation in spool travel, causing uneven line distribution and lumpy spool packing. Cross-references with Shimano part number RD9975. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
