What actually decides Endurant XD vs XD Pro?
We do not name a winner in Endurant XD vs XD Pro. There is no independent, like-for-like study of fuel economy or reliability for these transmissions. These are the facts that decide it for a given truck and duty cycle.
- The extra torque is the 2,050 lb-ft version
- The XD stops at 1,850 lb-ft. The XD Pro lists a third rating at 2,050 lb-ft, and that version carries the high-torque clutch label. If your engine makes more than 1,850 lb-ft, only the XD Pro lists a rating for it.
- Weight limit: a number or no limit
- The XD lists a 166,000 lb maximum combined weight. The XD Pro lists unlimited. If you run near 166,000 lb, or may in the future, that is the line to check.
- Reverse gears and clutch show the vocational focus
- The XD Pro adds three more reverse gears, at 3.08, 2.57 and 2.15, and an extreme-duty clutch. Eaton Cummins's list of vehicle types for it includes linehaul, heavy haul, logging, construction and wrecker work. For a line-haul truck, the extra reverse gears may never matter.
- Almost everything else is the same
- The ratios, the oil, the oil capacity and the oil intervals match on both pages. The Pro adds 5 lb. Eaton Cummins prints a warranty for neither, so get the written terms.
