GM G80 Gov-Lock 11.5″ 14 Bolt Differential Complete Clutch Kit

GM G80 Gov-Lock 11.5″ 14 Bolt Differential Complete Clutch Kit


Late model GM 11.5″ full G80 clutch kit

  • Uses heat treated and carbon fiber lined clutch plates
  • Has carbon fiber fuse disc setup
  • Comes complete with clutch ear bushings & ramp plate spring


You are buying a GM replacement clutch plate set for all GM G80 14 Bolt 11 1/2 locking differentials, all model years.

  • These are the later design clutch plates that have increased surface area for more apply and are much better than the earlier versions
  • These WILL NOT FIT ‘regular’ Eaton limited slip or posi units.
  • You get both clutch pack kits, everything that is pictured which is enough for one differential
  • These are the same clutch pack kits that we use in our rebuilt differentials
  • In most cases the internal clearances will have to be reset and the internal shimming will have to change
  • Fits all 11.5 FF differentials from 1999 to current

If your Gov-Loc is failing to unlock, popping in corners, making strange noises or acting funny it may be time for new clutches.  As the clutches in these units wear out, especially the thin or RHS, the ramp plate must over travel to achieve lock.  When this happens, it can get stuck in the locked position and catastrophic damage will result.

In addition, if it does not lock or has been abused, the fuse disc may be stripped or the governor assembly may be damaged. The fuse disc is included with the LHS clutch pack

Replace your clutch packs – NOT your differential.
