  • Introducing the strongest AR44 axle gears to date: Keyed Overdrive 27/8T HD Helical Bevel Gears + Differential Locker Set for AR44 housings #BR955029.

    The SCX10 II stock axle gears are known to be a weak point in the housing. After we released the popular Keyed 30/8T Hardened Steel Gears last year, fans of Boom Racing inquired about an OD version. So YOU asked, and we listened!

    Here is the new heavy duty overdrive 27/8T helical bevel gear & diff locker set.
    Designed for the Axial SCX10 II AR44 Axle Housing (AX-31401) or Boom Racing PHAT Axle Housing (BR955015) / the BRX70 and BRX90 PHAT Axles.

    Use this gear to improve performance of your crawler. Run them in the front axle for a faster wheel speed in the front tires. Overdrive gears help steering in sharp turns like how a dig does and climbing by pulling forward the rear end.

    Overdrive gears create faster wheel speed to help steering and climbing
    Hardened steel gears for maximum strength and durability
    Keyed spool to increase structural strength and to eliminate weakness of the M2.5 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
