1057F  (RD3516  Anti-Reverse Cam Spring)

Genuine Shimano Anti-Reverse Cam Spring (part #1057F) — a small but essential spring that maintains tension on the anti-reverse cam, keeping it properly positioned against the roller clutch bearing. A broken or fatigued cam spring allows the anti-reverse to slip, resulting in handle back-play and lost hookset power at the worst possible moment. Cross-references with Shimano part number RD3516. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
