PRODUCT Detail
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.
