Grip-N-Loc Limited Slip Differentials The Pro Series gives you the very best in controlled power transfer with lightning-fast reaction to changing load conditions.

Nothing delivers superior traction capability like an Auburn Gear performance differential!

For nearly 50 years Auburn Gear has been the leader in performance limited-slip differentials. Today, no matter what you drive - dragsters, performance cars, every-day passenger vehicles, light duty trucks, vans, sport utility, off-road, or recreational vehicles - there is an Auburn Gear performance differential engineered to maximize your vehicle's tractive capability


Features:

-A robust and unique cone clutch mechanism that outlasts and outperforms plate-type clutch designs.
-High strength bevel gearing that provides greater resistance to shock loading as compared to helical gear limited-slip designs.
-The mechanical advantage of a cone clutch versus a plate-type clutch provides quicker torque transfer under any driving condition.
-Torque sensing and biasing at any speed.
-Compatibility with ABS and electronic controls.
-Industry-leading One Year Warranty.
-Made in USA.

Grip-N-Loc® versus OE Limited Slip Differentials

1. Increased Bias Ratio – Improved Traction

The bias ratio of spring-preloaded limited-slip diffs varies significantly. As torque on the low traction wheel increases, the bias ratio decreases. For example, if we look at the bias ratio at the “Ice Line” (where the low traction wheel is on ice and its coefficient of friction = 0.1) the typical bias ratio will be approximately 4.5:1 up to 5.0:1.

As the low traction wheel gains traction the bias ratio will decline, delivering more traction to the lower traction wheel. For example, if the bias ratio is taken when the low-traction wheel experiences a .20 coefficient of friction, the bias ratio is only 3.0:1 to 3.5:1 (tire size and weight will also alter these values).

IMPORTANT – Average Bias Range with both axles on similar ground is 3.3:1 to 3.5:1.  However, when one of the tires encounters ice or snow, the bias ratio increases to 4.5 to 5.50:1. This means, the differential as a torque multiplier has the ability to transfer up to 5X the torque of the low traction wheel across the axle to maintain vehicle traction.

2. Case Material Optimized for Durability in Extreme Conditions

Auburn uses different grades of Nodular Ductile Iron case material depending on the application. Original equipment manufacturers typically use lower cost, less durable iron case material.

Additionally, OE cases are typically designed to optimize material cost/weight versus warranty cost considerations. Auburn products have greater mass and are made out of higher grade, more expensive materials. While not universal, in most applications Auburn diffs provide a case design that’s up to 50% stronger than OEs.

IMPORTANT – Auburn differentials are built with strength and durability in mind. We do not reduce material to achieve weight savings that compromise strength. Auburn differentials are specifically designed to provide confidence to enthusiasts who are upgrading their vehicles to put more power through the driveline and more torque through the axles.

3. Hardened Gear Material Minimizes Wear

High strength hardened steel is used for all of the gears in all Grip-N-Loc® applications. This material minimizes wear, adding long-lasting durability to moving parts and increases driver confidence in extreme conditions.

4. Gear Tooth Design…Exclusive Cone Clutches

Grip-N-Loc® continues the Auburn Gear tradition of using Cone Clutches to drive axle shafts. In Grip-N-Loc® we have optimized gear design for greater impact strength and toughness, rather than focusing on the cost versus warranty equation. The unique geometry of our side gear and cone clutch assembly increases overall durability, providing greater impact strength and overall toughness. For the high performance driver this provides the ability to push more horsepower through the differential to the wheels, without risk.

5. Exclusive Cone and Cup Design

This exclusive design has been the heart of our limited slip products for many years. A cone clutch side-gear unit creates friction with the carrier to drive both tires. The cone clutches couple with beveled side gears, providing highly efficient torque transfer to the axle shafts. As torque is transmitted to the axles, the side gear separating forces and preload spring seat the cones firmly against the differential case. The amount of force applied to the cone bearings determines the differential’s torque transfer capability. When torque levels decrease, as in a cornering maneuver, the gear separating forces also decrease, allowing the axle shafts to rotate independently and the wheel with the most traction receives the most torque.

6. New Cone Clutch Design for Increased Durability

The exclusive cone clutch design described above has been the heart of our differentials for many years. But Grip-N-Loc® cone clutches have been redesigned to provide increased durability.

Competitive testing showed Auburn diffs have very good retention of the torque bias characteristics. This testing was integral in driving us to change from a spiral (threaded) cone design to a new “grooved” cone design that has better wear resistance properties when forced to slip at higher speeds. A change in the cone angle takes further advantage of the improved wear characteristics resulting in an additional 25% increase in bias ratio for better performance.

These design changes address product durability and performance, allowing the bias ratio to remain consistent over the life of the vehicle. Features within the design improve oil flow and cooling of the differential to increase durability. These specific changes resulted in Auburn increasing the standard warranty to 2 years, which we believe to be the industries best warranty.*

Exclusive 2-Year Warranty

Because we build Grip-N-Loc® with heavy duty case material (up to 25% stronger than OE cases), designed the gears to deliver more impact strength, and redesigned our cone clutches to provide better oil flow and cooling, we have the confidence to offer an industry-best 2-Year warranty on Grip-N-Loc® diffs.

Be sure to use the included Auburn Gear Friction Additive to qualify for the 2-year warranty.*

*Note, Auburn Gear requires the use of their friction additive to be used in combination with a high quality mineral based GL5 oil, preferably Auburn specially formulated gear lube.
