Overview

The SCX10 II stock axle gears are a known weak point. Following the popular Keyed 27/8T Overdrive Hardened Steel Gears, this new heavy-duty 33/8T helical bevel gear and diff locker set was developed in response to customer requests for underdrive gears. Designed for the AR44/AR45/Capra Currie F9 Axle Housing, Boom Racing AR44 PHAT Axle Housing, or the BRX70/BRX80/BRX90 PHAT Axles.

Run these gears in the rear axle for slower wheel speed in the rear tyres. Underdrive gears help to steer in sharp turns similar to how a dig does, delivering slower wheel speed in the rear with higher torque output.

Note

This product will only fit one axle housing.

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

In the box

  • 1x Keyed Heavy Duty Bevel Gear 33T
  • 1x Heavy Duty Input Shaft 8T
