Ring and Pinion GEAR SET RT40-4N 3.58 Rear LOCKOUT CWP 43:12 (10 T ) 3.58 RTL44 04 Fits Freightliner
Heavy-duty differential ring and pinion gear set engineered for commercial truck rear-axle carrier assemblies, commonly utilized in Freightliner, Meritor, and MBA heavy-duty drive axle systems.
Core Characteristics & Functionality
- Primary Function: Transfers rotational power from the driveshaft to the axle shafts at a right angle while providing gear reduction to maximize drive torque.
- Gear Architecture: Features a high-precision hypoid bevel gear layout, where the pinion axis is offset from the center of the ring gear to maximize tooth surface contact, load capability, and operational smoothness under heavy haul conditions.
- Tooth Configuration: Features a 43-tooth ring gear paired with a matching 12-tooth pinion gear to yield a 3.58:1 gear ratio—designed to optimize highway cruise engine RPMs and fuel efficiency for long-haul fleet trucks.
- Axle Position: Engineered primarily for Forward-Rear tandem axle applications (specifically designed to fit models with or without inter-axle differential locks).
- Material & Construction: Drop-forged high-grade alloy steel (typically 8620 or 4320 steel), heat-treated and carburized for extreme impact resistance and extended fatigue life.
