  • Fully Machined, Forged Steel Case
  • Carbon-Fiber and Steel Clutches
  • Serviceable & Rebuildable Design
  • 1 year warranty against Manufacturer defects
  • Non-Synthetic GL-5 Gear Oil Recommended
  • Friction Modifier Required

- *Note: The GM 11.5" differential had a design change in mid 2011. The early design has a rear pinion race with an O.D. of 4.125". The later design has an O.D. of 4.375". This master bearing install kit is for the 4.375" O.D. size. Contact support if you need help figuring out what differential you have.
