2 Auto Replacement Stocks Poised to Gain From the Repair Boom

Read MoreHide Full Article

The outlook for the Zacks Automotive - Replacement Parts industry remains strong. The aging vehicle fleet in the United States — now averaging 12.6 years — is keeping repair volumes high. While tariff-driven volatility may temper new vehicle sales, it is encouraging owners to repair rather than replace, further boosting demand for parts and services. Meanwhile, the shift toward smart vehicles is opening new growth avenues, even as it requires adaptation to tech-heavy systems. Cost discipline remains important, but companies that can innovate while managing expenses are set to thrive. Industry players like Dorman Products (DORM - Free Report) and Standard Motor Products (SMP - Free Report) are worth considering at this point.

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 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 Cars, More Repairs: With the average U.S. vehicle now 12.6 years old, aging cars are hitting the repair shop more often. This growing trend boosts demand for replacement parts, as owners invest in maintenance to keep their vehicles running longer. It’s a big win for the auto replacement parts industry, which thrives as cars stay on the road well past their prime.

Tariffs to Cool New Car Sales, Boost Repairs: After a surge in early 2025 car purchases driven by tariff fears, U.S. auto sales are likely to lose steam. With higher vehicle prices and economic uncertainty, many consumers are opting to hold onto their current cars. That shift away from new purchases is expected to lift demand for replacement parts, as more drivers turn to repairs over buying new.

Tech-Driven Cars, New Aftermarket Opportunities: As vehicles become more advanced, with electrification, autonomous features, and complex software, the replacement parts industry is evolving fast. Today’s cars depend heavily on sensors, electronics and digital systems, which require specialized components and know-how. This shift is fueling demand for skilled technicians and cutting-edge diagnostic tools. Technology innovation is creating fresh opportunities for growth for industry participants.

Balancing Innovation With Cost Control: Innovation is fueling growth in the industry, but it’s also driving up costs. Developing components for EVs, autonomous tech, and high-efficiency vehicles demands heavy investment in R&D, skilled labor, and factory upgrades. In this environment, cost management is crucial. Companies that streamline operations and boost supply chain efficiency will be better positioned to protect margins while meeting automakers’ evolving needs.

Over the past five years, the industry has traded as high as 12.46X, as low as 7.99X and at a median of 10.39X, as the chart below shows.
