Description
Key benefits include:
* **Increased Power Transfer:** Upgrades your vehicle for safe transfer of increased power/torque across the axle.
* **Stronger Case:** Case material is up to 50% stronger than OE cases.
* **Advanced Cone Clutch Technology:** Provides a 25% increase in bias ratio for increased traction.
* **Heat-Treated Gears:** Hardened-steel gear materials for confidence in extreme conditions.
* **Exclusive 2-Year Warranty:** Industry-leading warranty due to robust design and materials, requiring Auburn Gear friction additive with a high-quality mineral-based GL5 oil.
The Grip-N-Loc™ utilizes exclusive Cone-Clutch technology to impart a bias across the axle when one wheel experiences low traction, shifting torque to the wheel with the most traction. This design ensures power distribution across the entire axle, helping to maintain forward motion. It features optimized gear design for greater impact strength and toughness, as well as a new "grooved" cone clutch design for improved wear resistance and oil flow/cooling.
