Fitment Notes

  • Fits the GM 10.5" 14-bolt truck rear differential - 1998-and-newer design with updated bearing sizes (YK GM14T-C); not compatible with pre-1998 GM 10.5" 14-bolt applications
  • For pre-1998 GM 10.5" 14-bolt applications, use YK GM14T-B instead
  • Ring gear bolts are NOT included in this kit - source separately (GM 14T ring gear bolts required)
  • Pilot bearing included - specific to the 1998-and-newer 14-bolt pinion design
  • The GM 10.5" 14-bolt was replaced by the AAM 11.5" 14-bolt in Silverado/Sierra HD trucks beginning with the 2001 model year for select configurations - confirm your specific axle type via the differential cover shape and casting numbers before ordering
  • The GM 10.5" 14-bolt continued in Express and Savana vans through the 2015 model year

Features

  • Complete all-in-one master overhaul kit - every required rebuild component for the 1998-and-newer GM 10.5" 14-bolt rear differential in one part number

  • Pilot bearing included - critical component unique to the updated 1998-and-newer 14-bolt pinion support design
  • Comprehensive shim kit included for precise pinion depth and carrier preload adjustment
  • Gear marking compound and brush included for ring-and-pinion contact pattern verification before final assembly
  • Thread locker, crush sleeve, and pinion nut included for complete hardware coverage
  • Differential cover gasket included - no separate sourcing required
  • Backed by Yukon Gear's 1-year warranty against manufacturing defects

Product Description

The Yukon YK GM14T-C is a complete master overhaul kit for the 1998-and-newer GM 10.5" 14-bolt truck rear differential - one of the most capable and heavy-duty axles GM installed in 3/4-ton and 1-ton trucks, HD Suburbans, full-size vans, and the Avalanche 2500. Rather than sourcing Timken bearings, seals, a pilot bearing, shims, and hardware separately, this kit consolidates every required rebuild component into a single, application-specific part number tailored to the 1998-and-newer GM 14T differential design.

A key distinction of this kit is the inclusion of a pilot bearing, which is specific to the updated straddle-mount pinion support design found in 1998-and-newer GM 10.5" 14-bolt differentials. The comprehensive shim kit covers both pinion depth and carrier preload adjustment, while gear marking compound and brush allow for accurate contact pattern verification before final assembly. Thread locker, crush sleeve, pinion nut, and differential cover gasket are all included - note that ring gear bolts are not included and must be sourced separately.

Builders should confirm their exact axle type before ordering. The GM 10.5" 14-bolt was largely replaced by the AAM 11.5" 14-bolt in Silverado and Sierra HD trucks beginning in 2001, though both axles were used across the same model years for different configurations. The GM 10.5" 14-bolt continued in Express and Savana commercial vans through 2015. For pre-1998 applications of the same GM 10.5" 14-bolt, use YK GM14T-B instead. All Yukon master overhaul kits are backed by a 1-year warranty against manufacturing defects.
