China’s automotive composite leaf springs market is projected to generate strong growth over the coming decade, reaching USD 25.3 million by 2035, according to recent industry forecasts. The market is expected to expand at a value-based CAGR of 5.3% between 2025 and 2035, fueled by regulatory support for energy-efficient transportation, rising commercial vehicle production, and the accelerating shift toward electric vehicles (EVs).
Composite leaf springs, typically made from fiberglass or carbon fiber materials, offer several performance advantages over traditional steel springs. These include 40–70% weight reduction, improved durability, enhanced fuel efficiency, and better handling stability. As automotive manufacturers focus on designing lighter and more energy-efficient vehicles, composite leaf springs are becoming an increasingly preferred suspension component across multiple vehicle categories.
Government Support and Industry Momentum
Supportive regulatory frameworks remain a central growth catalyst. China’s long-term goals for CO2 emission reduction, cleaner transportation, and improved fuel economy have encouraged automakers to integrate lightweight components. Composite leaf springs play a critical role in achieving these targets, especially as vehicle platforms become more optimized for efficiency.
The growing domestic automotive production base also contributes to market expansion. Strong demand across passenger cars, light commercial vehicles (LCVs), and heavy-duty trucks continues to create favorable conditions for adoption of high-performance suspension solutions.
