Automotive Air Springs Market Size, CAGR & Forecast, 2025-2035

Automotive air springs are shifting from a truck and bus product to a passenger EV product, led by Chinese suppliers

Radial Insights sizes the automotive air springs market at USD 6.18 Billion in 2025, growing to USD 6.54 Billion in 2026 and USD 10.96 Billion by 2035 at a 5.90% CAGR. Passenger car air suspension, once limited to luxury models, is now standard on many Chinese electric SUVs, and that change sets the pace for the whole market.

An air spring is a rubber bellows, usually fabric-reinforced natural rubber or chloroprene, clamped between metal or composite end plates and filled with compressed air. It replaces or supplements a steel coil or leaf spring and lets the suspension adjust ride height and stiffness to the load. Heavy trucks, trailers and city buses have used air springs for decades; the growth now comes from cars, where the springs are paired with compressors, valves and height sensors in a full air suspension system.

Our scope covers air spring units for road vehicles sold to vehicle makers and to the aftermarket: convoluted (bellows), rolling lobe and sleeve types for passenger cars, light commercial vehicles, heavy trucks, buses and trailers. Values are stated in USD Billion at the air spring or air strut assembly level. We exclude compressors, electronic control units and shock absorbers sold separately, as well as rail, industrial and seat air springs.

Battery electric vehicles are the fastest growing propulsion segment at 10.40% CAGR, and sleeve air springs are the fastest type at 7.80%. Asia Pacific is the fastest growing region at 7.40%, because Chinese EV brands such as Li Auto, ZEEKR, BYD and Avatr offer air suspension on mid-priced models.

Supply is also changing. In China, KH Automotive, Tuopu and Baolong together held 90.8% of passenger car air suspension fitments from January to May 2026, while Continental agreed in July 2026 to sell its ContiTech group sector to Lone Star Funds for an enterprise value of EUR 4.0 billion.

Passenger EV fitments grow at roughly twice the pace of truck and trailer air springs

Radial Insights segments the automotive air springs market by type, vehicle type, sales channel and propulsion. Growth splits along a clear line: passenger cars and electric vehicles grow fast from a smaller base, while heavy trucks and trailers, which still buy most units, follow freight cycles.

Sleeve air springs grow fastest by type at 7.80% CAGR

Convoluted air springs, with one to three bellows stacked between plates, grow at 4.60% and are used on trailer axles, cab suspensions and some bus axles. Rolling lobe air springs, the standard for truck and bus rear axles, grow at 6.40%. Sleeve air springs grow fastest at 7.80% because they fit inside passenger car air struts, often combined with an adaptive damper, and suit the compact packaging of EV platforms.

Passenger cars and SUVs lead vehicle growth at 8.20% CAGR

Passenger cars and SUVs grow at 8.20% as Chinese brands put air suspension on vehicles priced well below traditional luxury cars. Light commercial vehicles grow at 5.70% with load-leveling kits and electric vans. Buses and coaches grow at 5.60%, supported by electric bus fleets. Heavy trucks grow at 4.30% and trailers at 4.10%, both tied to freight demand in North America and Europe, where truck registrations fell in 2025.

OEM fitment outgrows the aftermarket, 6.30% against 5.10%

OEM sales grow at 6.30% because new air suspension programs in China and premium SUV launches add first-fit volume each year. The aftermarket grows at 5.10%, driven by replacement of worn bellows on trucks, trailers and older luxury cars, and by load-leveling kits from suppliers such as Air Lift Company.

Battery electric vehicles grow at 10.40%, hybrids at 7.10%

Battery electric vehicles are the fastest propulsion segment at 10.40%: heavy battery packs make adjustable ride height valuable for range and comfort, and lowering the car at speed cuts drag. Hybrids grow at 7.10%, including extended-range SUVs sold in China. Internal combustion vehicles grow at 3.20%, mainly through trucks, buses and trailers.

Market Trends

Chinese suppliers have taken over their home passenger car market

From January to May 2026, KH Automotive supplied 219,660 passenger car air suspension sets in China, a 35.2% share, followed by Tuopu with 188,869 sets (30.3%) and Baolong with 157,818 sets (25.3%), according to Gasgoo. Vibracoustic and AUMOVIO held 3.6% and 3.0%. KH Automotive had delivered more than 1 million air suspension sets by September 2025 across more than 27 models for Li Auto, VOYAH, ZEEKR, BYD and Avatr.

Air suspension is spreading from luxury cars to electric pickups and SUVs

Vibracoustic launched a single-chamber front and rear air spring system for a premium electric pickup in April 2025, with about 2 inches of ride-height adjustment for a truck rated to tow 10,000 lb. Electric pickups and large SUVs need load leveling for towing and adjustable height for range, which pushes air springs into segments that used steel coils.

Ownership of legacy suppliers is changing

Continental signed an agreement in July 2026 to sell its entire ContiTech group sector, a long-time air spring producer for trucks, buses and cars, to Lone Star Funds for an enterprise value of EUR 4.0 billion plus up to EUR 250 million in earn-outs, with closing expected by the end of 2026. In August 2025 Continental had already agreed to sell the ContiTech Original Equipment Solutions unit to Regent. Buyers expect new owners to focus on profitable truck and aftermarket lines.

Aftermarket suppliers are widening their air suspension ranges

Air Lift Company released the LoadLifter 5000 double-bellows air spring kit for the 2025 Toyota 4Runner in April 2026, rated for up to 5,000 lb of load leveling. Arnott launched P-3880 and P-5182 air suspension compressors for Audi, Bentley, Lamborghini, BMW X5 and Rolls-Royce models in May 2026. As the first wave of air-sprung SUVs ages, replacement demand for struts, bellows and compressors is rising.

Restraints and Challenges

Weak truck and trailer cycles in North America and Europe

EU truck registrations fell 6.2% to 307,460 units in 2025, with heavy trucks down 5.4%, according to ACEA. US trailer net orders were 13,000 in November 2025, 37% lower than a year earlier. SAF-Holland reported 2025 sales of EUR 1,734.4 million, down 7.6%, and expects North American trailer and Class 8 demand to stay subdued in 2026.

Price pressure from Chinese system suppliers

Chinese suppliers held more than 90% of their home passenger car air suspension market in early 2026 and are pushing system prices down. Tuopu has about 1.2 million sets a year of air suspension capacity. Lower prices widen adoption but squeeze margins for Western suppliers trying to win Chinese and export programs.

Durability and repair costs deter some buyers

Air springs wear as the rubber bellows flexes and ages, and leaks in older luxury cars lead to costly repairs. Some owners convert to coil springs rather than replace a full air strut, which caps aftermarket growth for passenger cars and creates warranty risk for OEMs offering air suspension on mass-market models.

Rubber and fabric input costs

Air spring bellows use natural rubber or chloroprene with nylon or polyester cord. The EU Deforestation Regulation, which applies to natural rubber from 30 December 2026 for large companies, adds traceability costs, and the suspension of a major US chloroprene plant in 2025 tightened that supply chain.

Growth Drivers

Chinese EV brands are making air suspension a mid-market feature

China built 34.53 million vehicles in 2025, according to CAAM, and new energy vehicles took a growing share. Chinese brands use air suspension to differentiate electric SUVs and MPVs: KH Automotive supplies more than 27 models, and the Gasgoo ranking counted about 624,000 passenger car air suspension sets fitted by the top five suppliers in China in just the first five months of 2026. Each set carries four air springs or air struts. Tuopu's chassis systems revenue reached CNY 8.72 billion in 2025. Radial Insights credits this driver with about +1.6% of yearly market growth, the largest single contribution.

Electric and low-floor buses depend on air springs

Every low-floor city bus uses air springs so the vehicle can kneel at stops and carry varying passenger loads. EU bus registrations rose 7.5% to 38,238 units in 2025, and 23.8% of them were electric, according to ACEA. Electric buses are heavier than diesel buses because of their batteries, which increases air spring load ratings and replacement frequency. Transit agencies in Europe, China and Latin America continue to order zero-emission fleets. We estimate bus demand lifts the CAGR by roughly +0.5% a year.

Truck parc growth and longer vehicle lives support replacement sales

China's heavy truck sales rose about 26% to 1.137 million units in 2025, the highest in four years. US Class 8 net orders reached 42,684 in December 2025, the strongest month of the year, and about 224,000 for the full year, according to ACT Research. Fleets keeping trucks longer during weak freight markets buy more replacement air springs: aftermarket business made up 39.7% of SAF-Holland's 2025 sales. Firestone Airide and Hendrickson serve this replacement channel. Radial Insights puts the contribution of truck and trailer replacement at close to +0.4% of growth each year.

Opportunities

Air struts for electric pickups and large SUVs in North America

Electric pickups and three-row SUVs need load leveling for towing and adjustable ride height for efficiency. Vibracoustic's 2025 electric pickup program shows OEM interest, and aftermarket kits from Air Lift Company widen the installed base for future replacement.

Smart air springs with integrated height and pressure sensing

Air springs with built-in height sensors and pressure monitoring allow predictive maintenance for truck fleets and smoother control in cars. Suppliers that combine bellows, sensors and valves into one module can sell higher-value assemblies to OEMs.
