This single 57-tooth spur is supplied as a one-piece replacement for AXIAL Racing SCX10 II vehicles. Built from Steel#45, the gear offers enhanced elastic recovery and better wear resistance over standard plastic spurs while retaining realistic drivetrain characteristics and resisting deformation during demanding runs.
Installation notes: install the 57T on the stock spur mount and check pinion engagement before the first session, confirm correct backlash and ensure gearbox lash is maintained to prevent excess wear. Apply thread locker to the supplied lock nut if required and re-check after a few break-in laps.
Tuning use: a steel spur like this helps preserve consistent mesh under heavy torque and when running low gearing for crawling, making it a useful complement to motor and gearbox tuning choices.
The product includes small hardware items provided with the gear: 15X33X1 fibre washers - 2pcs, 5.4X8.2X11.1X1.5 black springs - 2pcs, 4MM stainless steel lock nut - 1pcs.
Sold as a single unit with mounting hardware, this hardened 57T spur is suitable for scale crawling and drivetrain upgrades where additional durability is desired.
