Differential: Asphalt-Eating Traction

STaSIS differentials give you a big bang for your buck, increasing traction and improving handling to significantly enhance your vehicle’s performance. Our differentials automatically adjust power to all four wheels, delivering torque where you need it and when you need it so that you can put power to the ground for real-world performance gains from the engine enhancements you already have.   

For all-wheel-drive (AWD) vehicles, our high-bias torsen center differential improves the factory’s 2:1 and 4:1 torque distribution ratios, and can reach up to 6:1 depending on driving conditions. Our differential can deliver up to 88 percent of the available power to the wheels that need it most, translating to a significant reduction of wheel spin. This capability changes how your vehicle approaches each part of a turn by transferring power to the front or rear of the car as necessary: 

  • Hard braking leading into a turn—Car acts like a front wheel drive. Wheels turn independently and car control is improved.
  • Mid corner, throttle on—Car acts like an all wheel drive. STaSIS differential delivers equal amounts of power to front and rear wheels. This maximizes grip, allowing more power to be applied at this stage of a turn.
  • Corner exit, hard acceleration—Car acts like a rear-wheel-drive car. Front wheel slip is reduced because the STaSIS differential delivers up to 88% of the engine torque to the rear wheels where the most traction is.

For front-wheel-drive cars, our torque biasing front differential offers a dramatic performance improvement over t
