The Zacks Automotive Replacement Parts industry is benefiting from an aging vehicle fleet as consumers prioritize repairs to keep older cars on the road. The growing complexity of modern, technology-driven vehicles is also driving demand for advanced replacement parts. Additionally, President Trump’s tariffs are expected to elevate the prices of new cars, making repairs a more cost-effective choice. The industry’s valuation remains attractive compared to the broader sector and the S&P 500. Leading players like LKQ Corp LKQ, Dorman Products DORM and Standard Motor Products SMP are well-positioned, supported by strategic acquisitions and shareholder-friendly initiatives.
Industry Overview
The Zacks Automotive - Replacement Parts industry comprises companies that engage in the production, marketing and distribution of replacement components for the automotive aftermarket. The industry players offer replacement systems, components, equipment and parts to repair as well as accessorize vehicles. Some important auto replacement components are engine, steering, drive axle, suspension, brakes and gearbox parts. The auto replacement market is somewhat less exposed to business downturns as consumers are more inclined to spend on replacement parts to maintain their vehicles rather than splurge on new ones. Consumers can either opt for repairing vehicles on their own or can avail professional services for the same. The industry is undergoing a radical change, with evolving customer expectations and technological innovation acting as game changers.
Key Themes Shaping the Industry
Older Fleets to Drive Repairs: In 2024, the average age of vehicles in the United States reached a record high of 12.6 years, continuing a seven-year trend of steady growth. As cars get older, they require more repairs and maintenance, increasing the demand for automotive replacement parts and services. This aging fleet has become a key driver of industry growth, as owners must spend on upkeep to keep their vehicles running safely and efficiently. As a result, companies in the replacement parts sector are well-positioned to benefit from this trend.
Advanced Vehicles Creating New Opportunities: The auto industry’s move toward electrification, self-driving technology and digital features is reshaping the replacement parts market. Modern vehicles rely more on sensors, electronic systems and software-based components. As a result, the demand for skilled technicians and advanced diagnostic tools is rising. These changes are transforming the aftermarket industry, opening up new opportunities for growth.
Rising Car Prices to Boost Repairs: The upcoming 25% tariff on imported vehicles from Canada and Mexico, set to take effect next month, is expected to drive up new car prices. Some reports estimate that prices could rise by as much as $12,000. With already high vehicle costs, this could make it even harder for consumers to afford new cars. As a result, more car owners may choose to repair their existing vehicles instead of buying new ones, increasing demand for replacement parts.
Tariffs Threaten Auto Supply Chain: Many vehicles made in the United States depend on parts from Canada and Mexico. Research shows that Mexico supplies up to 40% of these components, while Canada contributes over 20%. New tariffs on these parts could disrupt the supply chain, raising costs for both automakers and consumers. Suppliers, already facing high expenses, may struggle to absorb the additional costs, which could lead to job losses and production slowdowns. As a result, industry players may face higher costs and pressure on profit margins.
