New GRIP-N-LOC™ Limited Slip Differential: BUILT TO EXCEED EXPECTATIONS!
Auburn Gear’s most advanced limited slip differential
Operation:
The new Grip-N-Loc™ builds upon exclusive technologies found in our previous limited slip line, but is re-engineered to be more robust to safely manage extreme demands. Grip-N-Loc™ is designed for those who push the limits of performance and traction, perhaps through competition, or simply through severe weather driving.
Grip-N-Loc™ Advantages:
- Upgrades vehicles for safe transfer of increased power/torque across the axle.
- Case material is up to 50% stronger than OE cases.
- Advanced cone clutch technology provides 25% increase in bias ratio/increased traction.
- Exclusive 2-year warranty.
