How to Measure Your Main Drive Shaft

The Ultimate Jigging Custom Power Arm (Model PA001) - with either a custom knob or T-Bar - fits selected Daiwa and Shimano spinning reels. To confirm compatibility, measure your reel’s main drive shaft (the threaded portion the handle screws onto).

 

🔴 How to Measure (Quick Guide)

⓵ Remove the handle from your reel.

⓶ Using calipers, measure the outer diameter (OD) of the threaded shaft in millimeters.

⓷ If your reel supports left and right cranks, check which side you use and measure that side’s threaded shaft.

⓸ Note the measurement and match it to the fit chart below.

💧Tip: Measure the threaded section itself (not the knob shaft). If in doubt, send us a photo and your measurements—we’ll confirm fit before you order.
