The automotive components sector ranks as the second-largest segment within the global vehicle industry. It encompasses manufacturing, distribution, remanufacturing, retail, and aftermarket services for car and truck parts, including installation of equipment, chemicals, and accessories. Parts may be produced by original equipment manufacturers (OEMs) or third-party suppliers.

The aftermarket industry offers two main categories: replacement parts and accessories. OEMs replace worn-out or damaged parts, while accessories enhance safety, comfort, appearance, or customization. Notable dealers such as Autozone, Napa, Rick’s Auto & Truck Parts, SAP USA, US Truck Parts, American Auto & Truck Salvage, Highway 64, Deercreek Auto Parts, and Collins Truck Parts are among the leading companies nationwide.

Manufacturers offer a wide range of automotive components, often providing DIY options for skilled vehicle owners. These materials enable self-repair and maintenance, saving money. The automotive aftermarket industry is valued at approximately $320 billion, employing about 4.2 million individuals in manufacturing, sales, repair, and distribution roles. Since 2015, demand for replacement parts and accessories continues to grow, reflecting increased vehicle maintenance needs.

Many consumers seek personalized modifications, though availability varies among dealers. Some possess global sourcing networks to import specialized parts from abroad, ensuring custom options for customers. Dealerships often handle middlemen in transactions, occasionally facilitating direct B2B deals. Achieving dominance in a local market can give retailers a competitive edge, especially with mass-produced vehicle components.

Online retailers like eBay and Amazon have revolutionized access to auto parts, offering convenience with home delivery services. Since 2014, their market share has expanded significantly, simplifying the purchasing process for consumers and providing a seamless shopping experience both online and through physical stores.
