Shimano 10ew4 Drag Spring Washer

Product Description

The SHIMANO 10ew4 is a drag spring washer designed for use in Shimano fishing reels. This small-but-critical component sits within the drag assembly and maintains consistent tension against the drag stack, helping the system deliver smooth, controlled line release under load. Installation is typically performed by tackle technicians or experienced anglers performing reel service. The part is sold in a quantity of 10 units per pack, making it practical for bench technicians who service multiple reels.

This drag spring washer is suited for reel maintenance and rebuild work where the original washer has fatigued, deformed, or lost its tension characteristics. The 10L designation indicates a pack quantity of 10 and fits the applicable Shimano reel model line. Technicians performing routine drag service or full reel overhauls will find this a direct OEM-sourced replacement component.

Installation Notes

Reel service should be performed by a qualified tackle technician or experienced user familiar with drag assembly disassembly procedures. Before servicing, release all line tension and fully disassemble the drag stack per the applicable Shimano service documentation. Avoid bending or distorting the washer during installation, as deformation will affect drag performance. Reassemble the drag stack in the correct sequence and test drag tension before returning the reel to service.
