The core idea
A truck isn't a model. It's a configuration.
Year + Make + Model is not enough for heavy-duty parts. A Peterbilt 389 can carry a Cummins, a PACCAR, or a Caterpillar; dozens of transmissions, axles, and ratios; different sleepers, wheelbases, and emissions generations. BigTruckParts.ai treats each configuration as a first-class object with its own proprietary ID — the DNA record of a truck.

Europe / METhe AI experience
A mechanic types. BigTruckParts.ai answers.
Natural language, VIN, or a bare part number — the AI traverses the graph and returns the exact part, its applicability, OEM number, supersession, aftermarket equivalents, and live inventory.
"Here's my VIN. Need the passenger-side hood mirror."
Part identified → applicability → OEM → superseded → aftermarket → sellers.
"3683918"
OEM 3683918 → Coolant Bypass Hose → superseded by 5498497 → Fleetguard / Dayco crosses.
"Upload a photo — what is this?"
Visual identification → matched part → full compatibility chain.
