  • NOTE1: ONLY high-quality, NON-SYNTHETIC 80W90 GL-5 spec gear oil treated with GM or Ford limited slip additive—aka friction modifier—must be used with Auburn differentials.
  • NOTE2: These high-performance items are not eligible for any further discounts or promotional pricing.

Auburn's torque sensing limited slip differentials use an innovative cone-shaped clutch, which engages the differential case, coupled to a beveled side gear providing max traction. When the differential senses one wheel spinning faster than the other, the cone clutch engages tighter, and through the use of springs and their preload, equalizes the torque bias to each wheel. They are available in two versions; one is the Pro Series for ultra-high-performance applications. The high-performance series has a standard spring preload for stock type street use, while the Pro Series uses much higher spring preload for instantaneous torque sensing traction.
