Shimano 108ha Dial Spring

Product Description

The SHIMANO 108ha is a dial spring replacement part designed for use in Shimano mechanical assemblies. A dial spring provides the tension and return force needed to maintain precise dial positioning within the mechanism it serves. This type of small internal component is typically serviced by a technician during a component rebuild or repair when the original spring shows signs of fatigue, deformation, or failure. Correct spring tension is critical to consistent dial feel and accurate function in the host assembly.

The 108ha is a Shimano OEM part intended for technicians performing component-level repairs on compatible Shimano assemblies. It is suited for service scenarios where the original dial spring must be replaced to restore proper function. Installation is best handled during a full disassembly and inspection of the dial mechanism.

Installation Notes
