PRODUCT INFORMATION:

  • Introducing the strongest AR44/AR45 axle gears to date: Keyed Underdrive 33/8T HD Helical Bevel Gears + Differential Locker Set for AR44/AR45 housings #BR955042.

    The SCX10 II stock axle gears are known to be a weak point in the housing. After releasing the popular Keyed 27/8T Overdrive Hardened Steel Gears, requests were sent in for underdrive gears. So YOU asked, and we listened!

    Here is the new heavy-duty underdrive 33/8T helical bevel gear & diff locker set.
    Designed for the AR44/AR45/Capra Currie F9 Axle Housing, Boom Racing AR44 PHAT Axle Housing or the BRX70/BRX80/BRX90 PHAT Axles.

    Use this gear to improve the performance of your crawler. Run them in the rear axle for a slower wheel speed in the rear tires. Underdrive gears help to steer in sharp turns like how a dig does and slower wheel speed in the back with higher torque output.

    Features:
    Underdrive gears create slower wheel speed for rear wheels to help steering with higher torque output
    Hardened steel gears for maximum strength and durability
    Keyed spool to increase structural strength and to eliminate the weakness of the M2 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

    Fits:
    Boom Racing BRX70 PHAT Axle
    Boom Racing BRX80 PHAT Axle
    Boom Racing BRX90 PHAT Axle
    Boom Racing PHAT AR44 Axle (BR955015)

      Does the job well
      Color: White, Size: 1.5FT(13A)
      I needed this as my wall outlet wasn't located near enough to my needs. Since it does exactly what the listing describes so, from my point of view, it gets 5 stars. Price was good. Well made.

      So convenient
      Color: White, Size: 5FT
      Perfect function for my charging system and the length is a right to my night stand. I like that it has surge protection, also I can plug in my phone and watch charger directly. I would buy it again next time.
