Boom Racing HD Helical Bevel Gear & Spool for Axial SCX10 II


The stock AR44 gears on the Axial SCX10 II are known to be a weak point on the axle. Boom Racing releases a new heavy duty helical bevel gear & diff locker to improve on its performance.

Hardened steel 30T/8T helical bevel gear and input shaft and differential locker (spool) set. Will fit the Axial SCX10 II AR44 Axle Housing (AX-31401) or Boom Racing PHAT Axle Housing (BR955015).


  • Hardened steel gears for maximum strength and durability
  • Keyed spool to increase structural strength and to eliminate weakness of the three M2 bolts
  • Tight tolerance of the diff locker and the axle shaft
  • Tight tolerance of the bevel gear and input shaft to increase efficiency in the drivetrain

Replaces the following stock Axial parts:
AX-31404- AR44 Differential Locker
AX-31405 - Heavy Duty Bevel Gear Set 30T/8T

MSRP: $32.9 USD
