RZ-166/RZ-188 tridem rear drive axle is ideal for construction, utility and other severe service applications where more tractive effort is required over conventional tridem axles. Engineered to deliver performance and durability, these axles are stronger and offer longer life under challenging operating conditions offering gross axle weight ratings (GAWR) up to 77,000 lbs.

Features & Benefits

  • Three driving axles for even distribution of the available tractive effort to the ground; all three axles are assumed equally loaded at all times
  • Utilizes Meritor® production tridem axles for parts commonality
  • Hypoid-Generoid gearing (18 inches or 19.6 inches) provides long life, exceptional strength and quiet operation
  • Precision-forged differential gears for more durability and strength
  • Optional driver-controlled differential lock (DCDL) for enhanced traction and spinout protection in slippery conditions
  • Optional pressurized, filtered tube system virtually eliminates the potential for spinout damage
