Heavy-duty Automotive Aftermarket Industry Size, Share & Trends Analysis Report By Replacement Part (Tire, Battery, Brake Parts, Filters, Body Parts, Lighting & Electronic Components, Wheels), By Vehicle Type, By Service Channel, By Region, And Segment Forecasts, 2025 - 2033

Heavy-duty Automotive Aftermarket Industry Summary

The global heavy-duty automotive aftermarket industry size was valued at USD 149.75 billion in 2024 and is projected to reach USD 204.26 billion by 2033, growing at a CAGR of 3.4% from 2025 to 2033. Rising technological advancements, such as the development of connected and autonomous trucks, advances in diagnostic tools, data analytics, and telematics, have become increasingly important in the market.

Better vehicle monitoring, predictive maintenance, and cost-effective repairs are expected to boost demand over the forecast period. The increasing adoption of electric and hybrid heavy-duty vehicles is creating a new segment in the aftermarket. Electric and hybrid vehicles have different powertrains and components compared to traditional internal combustion engine (ICE) vehicles. This shift in technology creates a demand for a new range of aftermarket products, such as batteries, electric motors, inverters, and charging infrastructure. Moreover, the growth of electric vehicles (EVs) necessitates the development of charging infrastructure, including charging stations, cables, and connectors. The aftermarket plays a role in providing these products and installing charging stations for commercial and fleet customers.

Additionally, digitalization and e-commerce are playing a significant role in driving the growth of the heavy-duty automotive aftermarket. Digitalization has led to the emergence of online marketplaces and e-commerce platforms specializing in heavy-duty automotive parts. Fleet operators, repair shops, and individual vehicle owners can conveniently browse catalogs, compare prices, and order parts online. Moreover, e-commerce platforms provide access to a vast array of aftermarket parts and products from various suppliers and manufacturers. Customers can explore a broader selection of products than they might find at traditional brick-and-mortar stores.

Government incentives, subsidies, and regulations related to vehicle maintenance and emissions control can influence the aftermarket. Programs aimed at reducing pollution or promoting cleaner transportation can drive demand for specific products and services. Furthermore, Startups and technology companies are entering the heavy-duty automotive aftermarket with innovative solutions, such as predictive maintenance platforms and digital marketplace platforms.

Replacement Part Insights

The other segment led the market and accounted for 46.9% of the global revenue in 2024. The rising trends of remanufacturing mechanical and electrical components are expected to drive the market demand for heavy-duty automotive aftermarket components, as remanufactured parts assist in minimizing expenses and support the continuity of older vehicles. Moreover, the retrofitting of components and parts reduced the emissions of an older heavy-duty vehicle, enhancing the life of that vehicle and thus directly driving the market demand for heavy-duty automotive aftermarket products.

The turbocharger segment is predicted to foresee significant growth in the forecast period. Turbochargers enable engine downsizing, where a smaller-displacement engine is equipped with a turbocharger to deliver the power output of a larger engine. This reduces fuel consumption and emissions while maintaining performance. Furthermore, the segment is crucial for enhancing the fuel efficiency of heavy-duty vehicles. As fuel costs remain a significant operational expense for fleet operators, there's a growing focus on adopting turbochargers to reduce fuel consumption.

Vehicle Type Insights

The class 7 to class 8 segment accounted for the largest market revenue share in 2024. Stricter emissions regulations are driving the demand for aftermarket emissions control technologies in Class 7 to Class 8 vehicles. This includes diesel particulate filters (DPFs), selective catalytic reduction (SCR) systems, and exhaust gas recirculation (EGR) components. Moreover, the integration of telematics and fleet management systems is growing in this segment. Fleet operators are using these technologies for vehicle tracking, maintenance scheduling, and route optimization, leading to increased demand for related aftermarket products and services.

The class 4 to class 6 segment is predicted to foresee significant growth in the forecast period. The installation of safety and driver assistance systems such as backup cameras, collision avoidance, and lane departure warning systems is growing in this segment. The aftermarket offers retrofit options for existing vehicles. Moreover, to reduce operating costs, medium-duty vehicle owners are looking for efficiency improvements. Aftermarket products like aerodynamic kits, tire management systems, and engine tuning can deliver fuel savings. Moreover, the integration of telematics and predictive maintenance solutions is reshaping parts replacement cycles and service intervals. As fleet operators prioritize cost efficiency and minimize downtime, the demand for high-quality replacement components, remanufactured parts, and digital service platforms continues to strengthen within this segment.

Service Channel Insights

The DiFM segment held the highest market share in 2024. The "Do it For Me" (DiFM) segment is characterized by services and maintenance performed by professional technicians or service providers on behalf of vehicle owners or fleet operators. This segment is essential for those who prefer to outsource vehicle maintenance and repairs rather than doing it themselves. DiFM providers often offer fleet management services that include maintenance scheduling, cost tracking, and compliance management. These services help fleet operators optimize vehicle performance and reduce operational costs. Additionally, fleet downtime costs are prompting operators to outsource repairs to ensure faster turnaround and quality assurance. This trend is further supported by digital service management platforms that enhance scheduling, transparency, and parts availability, strengthening the professional repair ecosystem in the heavy-duty segment.

The DIY segment is predicted to foresee significant growth in the forecast period. The Do-It-Yourself (DIY) segment refers to vehicle owners or enthusiasts who perform maintenance, repairs, and customization on their own vehicles without relying on professional mechanics or service providers. While the heavy-duty automotive sector traditionally has a strong professional service component. The availability of online resources, including repair manuals, instructional videos, and automotive forums, has empowered DIYers with the knowledge and confidence to tackle more complex projects. The availability of online diagnostic tools, e-commerce platforms for spare parts, and video-based learning has strengthened this movement. However, the complexity of modern heavy-duty vehicles and the need for specialized equipment still limit full-scale DIY adoption. Overall, the DIY trend is fostering greater consumer awareness and demand for user-friendly components, driving manufacturers to develop more modular and easily serviceable products.

Regional Insights
