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.
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
