Differential, Auburn, 7.5 Chevrolet 10 Bolt, 26 Spline

Auburn's torque sensing Limited Slip Differentials (LSD) use an innovative cone-shaped clutch, which engages the differential case, coupled to a beveled side gear providing max traction. When the LSD 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. The Auburn LSD's are available in two versions: one is the "Pro Series" for ultra high-performance applications. The "HP 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.


  • NOTE1: Only high-quality, non-synthetic 80W90 GL-5 spec gear oil treated with GM 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.
  • SHIP NOTE: This item is SPECIAL ORDER and will be drop-shipped from the manufacturer.
WARNING: This product can expose you to chemicals including lead, sulfur, nickel, chromium, vanadium, titanium, polyvinyl chloride, and 4,4’-methylenebis (2-chloroaniline), which are known to the State of California to cause cancer and birth defects or other reproductive harm.
