Helical Gear
Restore differential performance with the CCC Parts TDA3892L5940 Helical Gear. This OEM-style Meritor/Rockwell helical drive gear is used in power-divider and inter-axle differential carrier assemblies to transfer torque smoothly between drivetrain components. The helical tooth form spreads contact across multiple teeth, reducing noise and impact loads while improving strength under high torque. Ideal for carrier rebuilds or gear replacements when wear, pitting, or backlash appears. Available through Wofford Truck Parts.

Specifications
The TDA3892L5940 Helical Gear from CCC Parts is a direct aftermarket interchange for Meritor 3892L5940, commonly listed as a helical drive/transfer gear in Rockwell/Meritor differential and power-divider carrier systems. This gear’s angled (helical) teeth provide steadier meshing than spur gears, which helps reduce vibration and gear whine during load transfer. Manufactured to OEM geometry and heat-treated for wear resistance, it supports high-cycle commercial trucking service. Replacing a worn helical gear during a rebuild restores correct torque routing, protects mating gears and bearings, and improves driveline efficiency. Sold by Wofford Truck Parts.
