Our Standard

Why workshops buy from us

We specialise in one manufacturer, so we know its platforms, its part numbers and its failure points better than a general supplier ever could.

1

Original Specification

Every part matches GM's factory drawing for form, fit, function and material — no compromise substitutions.

2

Verified Part Numbers

Send us a VIN or an OE number and we confirm exact fitment before anything ships.

3

GM-Only Focus

A single-manufacturer catalogue means deeper stock on the parts that actually move.

4

Trade Support

Dedicated pricing, priority sourcing and account terms for workshops, fleets and resellers.

About Us

A parts company that only does GM

American O.E.M. Parts Company was built on a simple idea: a supplier that concentrates on one manufacturer will always serve the technician better than one that tries to stock everything.

We source replacement components manufactured to General Motors' original specifications, and we verify fitment against the vehicle before a part leaves our counter. That is the difference between a repair that lasts and a repair that comes back.

From a cooling fan clutch to a starter solenoid or an ignition coil, the standard is the same across all twelve of our categories.
