10BZ5  (RD16300  Pinion Gear)

Genuine Shimano Pinion Gear (part #10BZ5, RD16300) — the pinion gear is one of the two primary gears in your reel's drive system, meshing directly with the drive gear to convert handle rotation into spool and rotor movement. A worn, chipped, or stripped pinion gear causes grinding, skipping under load, and complete loss of retrieve power. Cross-references with Shimano part numbers 10BZ5 and RD16300. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
