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.

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.

Answers

Common questions

What does O.E.M. mean?

O.E.M. stands for Original Equipment Manufacturer. An OEM part is built to the vehicle manufacturer's own specification — the same form, fit, function and material as the part fitted at the factory — rather than to a generic aftermarket design.

Which vehicle brands do you cover?

We supply parts for the General Motors family: Chevrolet, GMC, Cadillac, Buick and Hummer, across passenger cars, SUVs, light trucks and heavy-duty platforms.

How do I confirm the correct part for my vehicle?

Send the VIN or the OE part number with your request. We verify exact fitment against GM records before quoting, and return a written quote within one business day.
