579 Specs & Options to Prioritize
| Spec Area | Typical Options | Why It Matters |
|---|---|---|
| Engines | PACCAR MX-13/MX-11; some Cummins X15 | Balance of torque, fuel efficiency, and service network |
| Transmissions | Eaton UltraShift/Endurant AMT; 10/12-speed manuals | AMT lowers fatigue in stop-and-go; manuals preferred by some drivers |
| Axle Ratios | ~2.28–3.08 for highway lanes | Match to cruise RPM for fuel savings and drivability |
| Sleeper & Cab | Mid/raised-roof 72”+, bunk HVAC, storage | Driver comfort = retention and safer, longer duty cycles |
| Safety Tech | Collision mitigation, lane assist, adaptive cruise | Fewer incidents and potential insurance benefits |

Pre-Purchase Inspection Checklist (579 Focus)
- Aftertreatment health: Scan for active codes; check DPF/DOC ash load, SCR/NOx sensors, regen history.
- Fuel economy baseline: Confirm axle ratio vs tire size; verify cruise RPM at 100–105 km/h.
- AMT specifics: Review clutch wear index, calibration history, software updates, and shift quality.
- Cooling system: Pressure test, inspect charge-air cooler and hoses.
- Suspension & brakes: Airbags, bushings, even lining thickness; slack adjusters within spec.
- Electrical & sleeper: Battery load test, alternator output, bunk HVAC, moisture/seal integrity.
If you plan preventive work post-purchase, consider Truck Repair Financing to spread initial costs.

- Kilometres vs. hours (idling profile matters)
- Service records (oil intervals, valve sets, DPF services)
