Product Description
Shimano 10CBS Anti-Reverse Pawl Spring (TGT0039)
The Shimano 10CBS Anti-Reverse Pawl Spring (TGT0039) is a critical safety and performance component found in the drive train of Shimano’s conventional and trolling reels. This spring provides the essential tension required to keep the anti-reverse pawl (the "dog") engaged with the ratchet gear.
This mechanical system is your reel's primary defense against "back-play," ensuring that the handle cannot spin backward when a fish strikes or during a heavy retrieve. Because this spring is constantly under tension and moves every time the handle turns, it is a common wear item. If your reel has developed a "clunking" sound or the handle slips backward, the 10CBS spring may be stretched or corroded. Replacing it with a genuine Shimano factory part restores the instant, reliable hook-setting power your reel was designed for.

Pro Tip: When installing the Anti-Reverse Pawl Spring, ensure the "loop" or "arm" of the spring is properly seated around the pawl. If the spring is installed upside down, it may cause the anti-reverse to fail or create excessive clicking noise.
