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

Spare 2.5x11 Drive Pins for RC Drivetrains

The HUDY 106061 kit offers four 2.5x11 drive shaft pins made to an extra hard specification to extend service life under repeated load cycles. These pins provide a simple retention solution in axle and driveshaft assemblies engineered for a 2.5mm pin diameter, helping to maintain tight fits and reduce unwanted movement between connected parts.

Installation involves removing the old pin and pressing the replacement 2.5x11 pin into the corresponding bore until it is fully seated. Check alignment and retorque any adjacent fasteners as required. Extra hard pins are less prone to deformation but still need correct insertion to avoid stressing neighbouring components.

During tuning and maintenance, replacing worn or bent pins supports steady gear mesh and consistent wheel timing, which can improve predictability when adjusting setups or testing changes.

Having these spares on hand reduces the chance of prolonged downtime and helps preserve setup consistency across practice and race days.
