Genuine Shimano Lever Shaft Body Mono Cam (part #10RR8) — this precision-machined component is part of the drag lever mechanism in Shimano conventional reels, controlling the cam profile that translates lever movement into drag pressure.

Compatible with select Shimano Tiagra and offshore lever-drag reels. OEM replacement ensures precise drag curve calibration and reliable lever action.
