Overview:

Whether you’re operating a regional haul or local duty-cycle, the Cummins X12 offers maximum payload for your weight-sensitive application.

Customers with Refuse trucks, Mixers and Tankers can set their expectations high with the X12.

  • Up to 500 HP and 1700 lb-ft of torque
  • Revolutionary low-friction design for higher MPG
  • Maintenance intervals that rival the X15 with longer Oil Drains and DPF maintenance beyond the first owner
  • Compatible with a broad choice of transmissions: fully automatic, AMT and manual

Regional-haulers with hub-and-spoke operations can expect their total cost of ownership (TCO) to drop significantly with the X12. A low-friction design increases fuel economy while extended maintenance intervals and high mileage, real-world experience ensures maximum uptime. Less time spent in the shop means more money earned on the road.

REPTO - Available - Torque limit of 466 lb-ft continuous, 516 lb-ft intermittently, gear drive ratio is 1.18:1, rotation is opposite of the crankshaft
