Product Description

SHIMANO 105R6 BAIL SPRING (RD17683)

Restore the Crisp Action of Your Flagship Reel

The Shimano 105R6 Bail Spring (Part No. RD17683) is the genuine OEM compression spring engineered for the bail return mechanism of Shimano's flagship spinning reels, most notably the 2014 Stella FI series. This high-tension spring provides the force required to snap the heavy-duty bail arm back into retrieval position instantly when the handle is turned.

In high-end reels like the Stella and Twin Power, the bail mechanism is precision-tuned for silence and reliability. If your bail feels weak, fails to flip over completely, or lacks that definitive "click" when opening, this spring is likely fatigued. Replacing it ensures your reel maintains the premium mechanical feel expected of a top-tier Shimano product.

Installation Tip: On the Stella and Twin Power, this spring fits over a plastic Bail Spring Guide (often Part RD15993 or RD16782). The assembly is housed inside the rotor arm. When installing, apply a light coating of Shimano Permalub (grease) to the spring and the plastic guide. This is crucial not just for lubrication, but to dampen any "spring noise" or vibration during the bail opening, maintaining the reel's silent operation.
