What should I replace at the same time?
Where labor overlaps, clean or renew the battery terminals and grounds with any charging-system repair.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2026 Freightliner XC was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2026 Freightliner XC?
Every part on this page already fits all 3 engine options (14.9L L6 DIESEL Turbocharged, 6.7L L6 DIESEL Turbocharged and 8.9L L6 DIESEL Turbocharged). Then test before replacing — a failed alternator and a bad ground can look identical, and sensors are frequently condemned for wiring faults. The notes column carries position and trim qualifiers where they apply.
