Boom Racing Hardened Steel Heavy Duty 8T/33T Keyed Bevel Helical Underdrive Gear Differential Locker Set
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 tyres. 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
- Tight tolerance of the bevel gear and input shaft to increase efficiency in the drivetrain
