What's the difference between OEM, OE and Aftermarket Parts?

When your truck or bus is due for repairs, maintenance, service or even an accident, your faced with a dilemma – weighing up the options of… OEM parts, OE parts and Aftermarket parts!? Does it really matter what parts are used on your vehicle?

It is important to understand the different types of parts, before deciding on what the right part is best for your bus or truck.

Original Equipment Manufacturer Parts (OEM)

OEM replacement parts are purchased directly from the vehicle’s manufacturer such as Mercedes, Volvo and Scania. Vehicle manufacturer make sure the parts are made to fit specifications of a certain make and model, so they fit perfectly. Often more than one supplier is used to make the same part.

These vehicle manufacturer branded parts come with a price tag and are generally more expensive than OE and aftermarket parts. Availability may also be limited depending on the manufacturer and the part you need.

Original Equipment Parts (OE)

There is normally confusion between OEM and OE parts. Original Equipment parts are from a company that design, manufacturer parts. The company may own the design, but the manufacturing of the parts are subcontracted to another company.

This is where Mercedes, Volvo and Scania contract the part to fit their specifications and design to other manufacturers like Behr or get modafinil. That OE part is then packaged and labelled with the Mercedes, Volvo and Scania logo on them. OE parts have the same quality of OEM parts but are more affordable as your not paying for a brand name.

Aftermarket Parts

Aftermarket parts are manufactured by a company different to the manufacturer of your bus or truck. It comes from a company that bystolic in copying replacement parts for different types of vehicles, not just a single truck or bus make and model.  The quality, material, and reliability is questionable making them the cheapest option.
