HRTRXM9022 Steel Helical Diff Ring/Pinion Underdrive 10/22 TRX4M

Precision machined steel helical differential ring and pinion set designed to provide an underdrive ratio (10 tooth pinion with 22 tooth ring) for TRX4M scale crawler differentials. The spiral cut helical design increases surface contact of gear teeth to deliver smoother meshing, reduced vibration, and greater strength than stock straight cut bevel gears, while the underdrive ratio enhances torque at the wheels for improved climbing performance.

• CNC machined steel helical ring and pinion gears improve strength and load capacity over stock plastic straight cut gears

• Underdrive 10/22 tooth ratio increases torque at the wheels and can reduce wheel speeds for better climbing control

• Helical spiral cut design delivers smoother engagement with less vibration and noise during operation

• Durable high carbon steel construction resists wear and withstands high load conditions

• Compatible with front or rear differential housings on TRX4M vehicles

• Precision machining promotes accurate gear mesh and consistent drivetrain performance

• Ideal for trail and technical crawling where enhanced torque and drivetrain durability are desired
