This 81T spur is a single-piece steel #45 unit built to replace worn 48 pitch spurs on Axial SCX10 and Wraith models. It is supplied as one component and follows the 48 pitch specification for compatible gear trains.
As the main spur gear, it must be matched with a 48 pitch motor pinion. Fit the gear using your vehicle's original securing parts and fine tune mesh and alignment for quiet, reliable engagement.
Opting for steel #45 gives better abrasion resistance for long sessions on rough terrain; always check tooth count and pitch when changing gear ratios or upgrading pinions.
