Auburn Gear
From over the road daily driving to muddy trails and back roads, Auburn Gear's high bias Pro Series and High Performance Series limited-slip differentials outperform standard OEM differentials hands down. They deliver more traction and faster engagement for controlled power transfer and lightning-fast reaction to changing load conditions. No matter what your application - performance or passenger cars, light duty trucks, vans, sport utility vehicles, off road, or recreational vehicles - the Auburn Gear limited-slip differential is engineered to provide smooth torque-sensing operation with bias ratios to meet your performance needs. This superior performance is achieved through an innovative cone clutch design which transfers more power to the high-traction wheel for quick acceleration and tight cornering. Auburn Gear has a full range of differentials for Chrysler, Ford, GM and Toyota vehicles. All are also compatible with all ABS and electronic controls.
How the Auburn Gear Limited-Slip Differential Works
The highly efficient torque transfer capability of the Auburn Gear limited-slip differential is achieved through the use of cone clutches coupled to beveled side gears. As torque is transmitted through the differential side gears to the axle shafts, the side gear separating forces and spring pre-load firmly seat the cones into the differential case. The cone design, along with the applied force, determines the torque transfer capability of the differential. When torque levels decrease, as in a cornering maneuver, the gear separating forces also decrease, allowing the axle shafts to rotate independently. All Auburn Gear limited-slip differentials are designed to provide the maximum amount of torque transfer without compromising the performance requirements of a vehicle in situations where torque transfer is not required.
State-of-the-Art Design and Test Lab
You get exactly what you specify -- faster and at a lower cost -- with Auburn Gear's CAE/CAD system, complete with Finite Element Analysis [FEA]. This system allows us to develop and optimize the differential design for your requirements.
These designs are challenged in the real world with our prototype testing labs, where every aspect from metallurgical properties to mechanical performance is proven against the design parameters. Our axle dynamometer tests the differentials to prove the design under load conditions while computer-aided manufacturing systems produce components to individual design specifications.
But testing is not confined to in-house labs alone. Our unique on-site testing capability brings engineers right into the field to prove the design of our limited-slip differentials under actual working conditions. Differentials are subjected to a variety of rigorous vehicle tests to assure you of getting the high performance reliability you need.
Located in the industrial heartland of America, Auburn Gear has the capability and capacity to meet increasing world market demands for traction-enhancing differentials, all while maintaining and improving every aspect of design, quality, delivery, and price which translates to total customer satisfaction for you.
