The Freightliner M2 — the Business Class 106 and 112 — might be the most common medium-duty truck in America: box trucks, tow rigs, dump bodies, reefers. It earns its living in town, which is exactly why bumpers and mirrors top its replacement list. Everything below is a direct-fit aftermarket replacement for the M2 106 and M2 112, with OEM cross-references.
Quick answer: the M2 headlight crosses to A06-51039-002 / A06-51039-003. The bumper is a three-piece system — center A21-26683-005 plus left and right corners (plastic 2126517-000F family or chrome A21-27811-016 family) — or grab the complete assembly and do the whole nose in one order.

Frequently Asked Questions
Do I need the whole bumper or just one piece?
Usually just one piece — that is the point of the three-section design. A clipped corner means a corner bumper; a square hit on the nose means the center section; and if the whole face is rough, the complete chrome assembly resets everything at once.
Plastic or chrome corners — which do I have?
Look at the finish on the truck today: dark plastic corners cross to the 2126517-000F family, bright corners to the A21-27811 chrome family. Both bolt to the same truck, so this is also your chance to switch looks.
Are the mirrors heated?
Yes — both the black and chrome 563.46025C door mirror assemblies are heated and powered, per the listings.
Do you ship to the US?
