  • 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 gears for maximum strength and durability, increased weight in the axle
    • Keyed spool to increase structural strength and to eliminate weakness of the three screws
    • 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

    • 1x Heavy Duty Input Shaft 8T
    • 1x Keyed Differential Locker (Spool)
    • 3x M2.5 hardware
