2.5x11 Extra Hard Replacement Drive Shaft Pins 4 pcs - HUDY 106061  [HSP-106061]

2.5x11 Extra-Hard Drive Shaft Pins

The HUDY 106061 replacement pack contains four 2.5x11 drive shaft pins produced to an extra hard grade to increase wear life in small-scale drivetrains. These pins act as basic retention elements within axle and driveshaft connections that accept a 2.5mm diameter pin, offering a low-profile way to reduce unwanted movement between linked parts.

To fit, remove the damaged or worn pin from the driveshaft or coupling then press the new 2.5x11 pin into the corresponding hole until it seats flush. Recheck alignment and re-tighten any retaining fasteners. While extra hard pins are less likely to deform, they still need proper seating to prevent introducing stress to surrounding components.

In maintenance cycles they are simple parts that influence drivetrain consistency; timely replacement of compromised pins helps keep gear mesh and wheel timing predictable across test sessions and events.

Store a set with your spares so you can quickly restore drivetrain integrity and carry on with setup or practice without long delays.
