Replacement Drive Shaft Pin Set 3x11 Extra Hard HUDY 106071  [HSP-106071]

3x11 Drive Pin replacement details

This HUDY 106071 kit contains four 3x11 drive shaft pins for RC-scale drivetrains, specified in the Extra Hard material grade by the manufacturer. The set is provided as 4 pcs to serve as spare pins for any driveshaft design accepting 3x11 pins.

Fitting is simple: each pin locates into the corresponding 3 mm bore and 11 mm slot on the shaft and should be retained using the original fastening method from the vehicle. Carry out assembly on a clean bench, confirm correct fit before tightening, and replace pins in matched groups to preserve drivetrain balance.

During tuning and routine upkeep these pins are small replaceable items that affect backlash and alignment; choosing the Extra Hard variant helps keep pin profile under heavier loads encountered in competitive or spirited running.

The HUDY 106071 set is a compact spares option for RC drive trains that use 3x11 pins, useful for regular servicing and tuning when harder matched pins are required.
