10X41 Crown Wheel Pinion with 4.10:1 Final Drive Ratio and Hypoid Spiral Bevel Design for Isuzu TFR D-MAX 4WD
Precision-engineered hypoid final drive gear set (crown wheel & pinion) that provides the final torque multiplication and speed reduction from the transmission to the wheels. Delivers optimal power transfer and drivability for Isuzu 4WD pickups and SUVs.
The Final Drive Gear Set (OEM Numbers: 8-97063573-0), also referred to as a crown wheel and pinion or ring and pinion set, is a premium-quality, direct replacement drivetrain component engineered specifically for ISUZU TFR, TFS, D-MAX, RODEO and compatible Isuzu 4WD vehicles equipped with front and rear solid axles.
This hypoid gear set is the heart of the axle assembly, responsible for the final reduction of rotational speed and the multiplication of torque before it is transmitted to the wheels. The 10X41 tooth count delivers a 4.10:1 final drive ratio, the factory-standard gear ratio for many Isuzu 4WD models, offering an ideal balance between low-end pulling power and highway cruising efficiency.
Manufactured to meet or exceed original equipment (OE) specifications, this matched ring and pinion set is forged from high‑strength, case‑hardened alloy steel and precision‑ground using advanced Gleason gear cutting technology.
