Automotive aftermarket distribution model

CLICK TO ENLARGE: Distribution channels in the auto parts industry. The dashed lines indicate a relatively new channel of distribution in the auto parts market, from internet retailers sending drop ship orders to WDs, who in turn ship directly to auto aftermarket consumers.

The automotive aftermarket is the after-sales auto parts market. This chart shows the complexities of distribution for the auto parts industry and aftermarket accessories.

“Two-step distribution” was the primary channel of distribution for aftermarket auto parts for decades. This distribution channel went from manufacturer, to warehouse distributor (WD), to the auto parts retailer/jobber, to the consumer.

This has given way to multiple channels of distribution in the auto parts market, as the internet has opened new channels of distribution and consumer buying. A prime example of this is shown with the dashed lines: internet retailers who take orders for parts and accessories, send orders to warehouse distributors (WDs), who then drop ship orders directly to consumers. Manufacturers are increasingly selling direct to consumer (DTC) on the internet, bypassing all other traditional distribution channels.

Common automotive aftermarket questions

Why is it called the aftermarket anyway?
This is a “market” for parts and accessories “after” a vehicle is sold, so it’s called the aftermarket. It’s the secondary market of the automotive industry. These are replacement parts and accessories sold after a vehicle is sold as new, intended for repair, customization or enhancement.

Which is better, OEM or aftermarket?
There is no “better” level of quality when it comes to OEM or aftermarket parts. OEM replacement parts are made by the manufacturer of a vehicle or for the manufacturer according to the manufacturer’s specifications. Aftermarket parts can be made to similar specifications or in some cases may exceed OEM specifications. In some cases there is no OEM equivalent to an aftermarket part.
