Shimano 1048S (BNT1307) Clutch Pawl Spring: Essential for Reliable Reel Engagement
Restore the crisp, reliable performance of your Shimano baitcasting reel with the genuine Shimano 1048S Clutch Pawl Spring. This essential component, also known by the part number BNT1307, is crucial for the proper function of your reel's clutch system, ensuring seamless engagement and disengagement of the spool.
Crafted from high-quality, durable spring steel, the 1048S is engineered to Shimano's exacting standards for a precise fit and optimal performance. This spring provides the necessary tension for the clutch pawl to securely engage the ratchet, preventing slippage and ensuring a solid hookset. Over time, the original spring can fatigue or break, leading to a mushy feel at the thumb bar, failure to engage the spool, or inconsistent performance. Replacing a worn or damaged clutch pawl spring with the genuine 1048S (BNT1307) part will restore your reel to its factory-level functionality.
