Product Details

The Yukon Gear & Axle YG GM9.5-488-12B is a high performance ring and pinion gear set engineered for 2014 and newer GM 9.5" axle assemblies in a 4.88 gear ratio. Designed as a direct replacement that meets OEM fitment specifications, this gear set is built for drivers who demand more from their drivetrain—whether towing heavy loads, off-roading, or regearing after a tire size upgrade.

Key Features:

  • 4.88 gear ratio optimized for 2014 & up GM 9.5" rear axle applications
  • High-grade steel construction used in both ring and pinion for maximum strength and durability
  • Precision-engineered gear tooth surface finish reduces friction and heat buildup during operation
  • OEM-spec fitment ensures proper mesh, contact pattern, and backlash for reliable installation
  • High performance standard — Yukon ring and pinion sets are among the most widely trusted in the aftermarket industry
  • Manufactured to tight tolerances for quiet, smooth operation

The GM 9.5" 14-bolt axle is a heavy-duty platform found in many GM half-ton and three-quarter-ton trucks and SUVs. The 4.88 ratio is a popular regear choice for lifted trucks running larger tires, restoring power, acceleration, and fuel efficiency that may be lost after a tire size increase. Yukon's YG GM9.5-488-12B delivers the strength and precision needed for both street and off-road use.
