Hot Racing HRAATF9337 Steel Helical Diff Ring and Pinion ARRMA BLX 3S 4S

The Hot Racing HRAATF9337 is a steel helical differential ring and pinion gear set engineered for ARRMA BLX 3S and 4S vehicles. Helical-cut teeth provide smoother, quieter gear engagement compared to straight-cut stock gears, while the steel construction delivers the strength needed to survive the high torque output of 3S and 4S brushless systems through aggressive bashing.

Key Features

• Steel construction for superior strength over stock differential gears
• Helical gear cut for smoother, quieter differential operation
• Handles high-torque output of 3S and 4S BLX motors
• Replaces stock ring and pinion as a matched set for optimal mesh
• Direct-fit upgrade for compatible ARRMA BLX platforms

Compatibility

Compatible with ARRMA BLX 3S and 4S vehicles.
