Product Description

SHIMANO 105FY BAIL SPRING (RD 8220)

Restore Your Bail’s Snap

The Shimano 105FY Bail Spring (RD 8220) is the genuine OEM compression spring responsible for the automatic return mechanism of the bail arm on many Shimano spinning reels. Located inside the rotor (usually on the side opposite the line roller), this spring stores the energy needed to "snap" the bail closed when you turn the handle after a cast.

If your bail arm feels limp, stays open when you try to reel, or fails to lock securely into the casting position, this spring is likely broken or fatigued. Replacing it is a simple repair that brings back the crisp, positive engagement of your reel's casting system.

Installation Tip: The bail spring usually sits over a plastic Bail Spring Guide (often part RD 8219) and interacts with a Bail Spring Seat. When installing, ensure the spring is compressed straight; if it bends sideways, it will bind. Apply a small amount of grease to the spring and the guide to prevent corrosion and ensure smooth operation.
