Ask three research firms how big the global commercial vehicle aftermarket is and you will get three different answers — but they all point in the same direction: up. Current commercial vehicle aftermarket market size estimates cluster between roughly USD 280 and 350 billion for the mid-2020s, with firms such as MarketIntelo projecting about USD 285 billion in 2025, growing at just over 4% a year toward roughly USD 400 billion by 2034. Other research houses publish figures in a similar band, and growth forecasts across the field cluster in the low single digits — roughly 2.5% to 4.5% a year, depending on scope.
Why the spread? Scope. Some analysts count parts only; others fold in service labor, tires, and light commercial vehicles. After two decades of buying parts for fleets, my advice is to ignore the decimal points and watch the drivers instead: fleet age, vehicle parc, distribution channels, and regulation. Those four tell you where prices, availability, and quality are heading.
This article walks through the numbers that can actually be verified, the forces pushing the market, how the independent aftermarket is faring against OE dealer networks in Europe, and why a new generation of manufacturers — with Türkiye front and center — is reshaping the supply base. It closes with what all of this means when you are staring at a quote sheet.
Commercial Vehicle Aftermarket Market Size: What the Numbers Say
Headline figures first. MarketIntelo puts the global commercial vehicle aftermarket at USD 285 billion in 2025 and USD 297 billion in 2026, on its way to roughly USD 399 billion by 2034 — a compound annual growth rate of about 4.2%. Other published forecasts land higher — Global Market Statistics, for one, puts 2026 at roughly USD 345 billion — largely because scope definitions differ on service revenue and vehicle classes.
Regionally, Asia-Pacific is the largest market at roughly 38–39% of global value, driven by the enormous truck parcs of China and India. Europe and North America are smaller but richer per vehicle: older fleets, higher labor rates, and stricter inspection regimes mean each truck consumes more aftermarket value every year it stays in service.
Here is the market in five verifiable data points:
| Indicator | Latest verifiable figure | Source (named, not linked) |
|---|---|---|
| Global CV aftermarket value | ≈ USD 285 billion (2025), heading toward ≈ USD 400 billion by 2034 | MarketIntelo |
| Typical growth rate | ≈ 2.5–4.5% per year, depending on scope | MarketIntelo, Global Market Statistics, others |
| Largest region | Asia-Pacific, roughly 38–39% of global value | MarketIntelo |
| Average EU truck age | 14.1 years — the oldest of any vehicle category | ACEA, Vehicles on European Roads (2025) |
| Türkiye automotive exports | USD 41.5 billion in 2025; ≈ USD 16 billion from the supplier industry | OİB (Uludağ Automotive Industry Exporters' Association) |
Treat every one of those numbers as a directional reading rather than gospel. The useful signal is that no credible forecast shows the aftermarket shrinking this decade.
Aging Fleets and a Growing Parc: The Aftermarket's Twin Engines
According to the 2025 edition of ACEA's Vehicles on European Roads report, the average truck on EU roads is 14.1 years old — the oldest of any vehicle category, ahead of vans and buses at around 12.5 years. The spread is dramatic: Greece runs the oldest truck fleet at 22.6 years, while Austria's averages just 6.8. Every one of those aging trucks is out of warranty, out of the dealer's contracted service network, and squarely in independent aftermarket territory.
Age matters because parts consumption is not linear. A three-year-old tractor under a repair-and-maintenance contract consumes filters and brake pads through the dealer. A ten-year-old unit on its second owner consumes clutches, compressors, calipers, wheel bearings, and air dryers — the expensive stuff — and its owner shops on price and availability, not brand loyalty.
At the same time, the parc keeps growing. Freight demand, e-commerce logistics, and construction keep adding registrations in every major market, and each truck registered today represents ten to fifteen years of future parts demand. High new-vehicle prices and financing costs have also pushed fleets to sweat existing assets longer — and deferring replacement is, mechanically, a decision to spend more on repair.
E-Commerce Is Rewiring Parts Distribution
The next structural trend is channel shift. B2B parts platforms, manufacturer web catalogs, and online marketplaces have made cross-border price comparison routine. A buyer in Rotterdam can check a part's price from distributors in three countries before lunch — something that took a week of faxes when I started in this trade.
Two consequences follow. First, price transparency compresses distributor margins and rewards manufacturers who publish clean, searchable catalog data with accurate OEM cross-references. If a part cannot be found by its OEM number online, commercially it does not exist. Our guide on cross-referencing OEM part numbers covers how to do this without getting burned.
Second, the same open channels that carry good parts also carry counterfeits and gray-market stock. The e-commerce boom has turned supplier verification from a nice-to-have into a core purchasing skill — more on that below.
Fleet Consolidation and the Right-to-Repair Push
Fleets themselves are consolidating. Larger operators centralize procurement, negotiate national supply agreements, and demand consistent multi-brand coverage from fewer suppliers. That professionalizes purchasing: big fleets audit suppliers, track cost per kilometer by part brand, and switch without sentiment. Distributors respond by consolidating too — international buying groups and trading networks now negotiate on a scale individual wholesalers never could.
Regulation is pulling in the same direction. In the EU, the Motor Vehicle Block Exemption Regulation (Regulation 461/2010, amended by Regulation 2023/822 and currently running to May 31, 2028) obliges vehicle manufacturers to give independent operators access to technical and repair information, keeping multi-brand workshops viable. In the United States, EPA guidance requires heavy-duty engine makers to make emissions-related repair information available to independent shops, and the federal REPAIR Act — which would broaden access to telematics and diagnostic data — cleared a House Energy and Commerce subcommittee unanimously in February 2026 and moved to the full committee, according to the Auto Care Association.
The direction of travel is clear: as trucks become software-defined, lawmakers on both sides of the Atlantic keep reasserting the independent sector's right to fix them. That legal floor protects the competitive market this article describes — and it matters more with every sensor added under regulations like the Euro 7 emissions rules.
IAM vs. OES: How the Share Battle Is Playing Out in Europe
Two channels compete for every parts euro. OES (original equipment services) parts are sold through the vehicle maker's dealer network, whether built in-house or by its Tier-1 suppliers in OE boxes. The IAM (independent aftermarket) is everyone else — Tier-1s selling under their own brands, independent manufacturers, and the distributors between them and your workshop.
Across the total European automotive aftermarket, analyses from Roland Berger and BCG consistently put the independent channel at roughly half of parts-and-service value, with commercial vehicles accounting for around a fifth to a quarter of the total. In trucks specifically, OES dominates the early years, when warranty terms and repair-and-maintenance contracts lock vehicles into dealer networks. The IAM wins the vehicle's second life, when price sensitivity rises and dealer proximity stops mattering.
The OEMs are not conceding quietly. Frost & Sullivan has tracked years of OEM counterattacks: all-makes parts programs, multi-brand workshop concepts, and telematics-driven service contracts designed to keep aging trucks inside the network. The result is a genuinely contested middle ground — trucks aged roughly four to eight years — where connected-vehicle data gives dealers an edge but price still pulls buyers toward the independents. For a part-level comparison of the two channels, see our breakdown of OEM vs. aftermarket truck parts.
The Rise of Tier-2 Manufacturers: Türkiye as a Case Study
The most underreported trend of the past two decades is the maturing of parts manufacturers outside the traditional Western European Tier-1 club. Nowhere is that clearer than in Türkiye. Automotive is the country's largest export sector: USD 41.5 billion in 2025 — about 15% of all Turkish exports — of which the supplier industry contributed roughly USD 16 billion, according to figures from the Uludağ Automotive Industry Exporters' Association (OİB).
That did not happen overnight. Türkiye assembles trucks, buses, and light commercials for global OEMs, and decades spent inside those supply chains built a base of component makers that now compete internationally under their own brands. Vaden Original is a representative example: founded in 1968 in Konya, it has grown into a 105,000 m² operation with more than 1,500 employees, exports to over 110 countries on five continents, and has produced more than one million air brake compressors. Its catalog spans 12,000+ OEM-compatible references across roughly 789 product groups — breadth that used to be the preserve of legacy European names.
Call these firms "Tier-2" if you like, but the label undersells the better ones, which run modern machining, in-house test rigs, and full traceability while a leaner cost base lets them price aggressively without cutting corners. What separates a genuine OEM-quality manufacturer from a box-label operation is a specific, checkable set of attributes — we cover them in what OEM-quality aftermarket actually means.
What All This Means for Parts Buyers
Put the trends together and the buyer's position in 2026 is enviable — with one catch. More manufacturers, more channels, and stronger repair rights mean more choice and sharper prices than this market has ever offered. The catch: the burden of quality verification has shifted from the channel to you. When everything is available, filtering becomes the job.
Practical moves that pay:
- Cross-reference before you buy. Confirm the OEM number match yourself rather than trusting a listing title.
- Demand documentation. In Europe, replacement brake linings, pads, and discs require UN ECE R90 type approval — ask for the certificate. For everything else, ask for material certificates and test reports.
- Weigh the manufacturer, not just the part. Decades in business, export footprint, catalog breadth, and OE-supply history are hard to fake.
- Pilot, then scale. Prove a new brand on a defined vehicle group before a fleet-wide rollout.
- Track cost per kilometer, not price per part. A part that costs 30% less but lasts half as long is not a saving — and your maintenance records already hold the data to prove it either way.
Workshop tip: When trialing a new parts brand, fit it to one axle position across several vehicles rather than to one whole vehicle. You get comparable wear data against your incumbent brand under identical duty cycles, and a single early failure never takes out an entire vehicle system.
The longer game is worth watching too. Zero-emission drivetrains will eventually shrink some wear-part categories, while air systems, foundation brakes, and chassis parts carry on regardless — our look at electric and hydrogen trucks maps which is which. And for a structured approach to supplier selection from first inquiry to first order, start with the truck parts buying guide.
The commercial vehicle aftermarket is bigger, more open, and more competitive than at any point in my working life. The buyers who win in it are not the ones who find the lowest price — they are the ones who build a verification habit and let the market's new breadth work for them.
