This steel spur gear serves as a direct replacement for the Axial EXO platform, offered as 1 pcs for routine maintenance or race-day swapouts. It is a 48-tooth spur explicitly intended for RC-scale drivetrains and manufactured in steel to address wear resistance under normal hobby use.
Installation notes: verify gear mesh with the matched pinion, confirm shaft alignment and bearing condition, and secure with the original retaining fasteners. Proper mesh and a clean bearing run are the main factors that affect noise and premature tooth wear.
Tuning role: swapping to a hardened-steel spur gear is primarily about durability and consistent engagement when testing different gear ratios or when running at higher torque from upgraded motors and ESCs. Keep an eye on clearance and lubrication for optimal service life.
