THE FUTURE OF AIR SUSPENSION: PERFORMANCE, COMFORT & EFFICIENCY

Air suspension systems are redefining vehicle dynamics by delivering superior ride quality, safety, and efficiency. As electrification reshapes the industry, modern vehicles require suspension systems that support additional weight while maintaining optimal performance. Unlike traditional mechanical suspensions, air springs dynamically adjust to road conditions, vehicle loads, and driving behavior, ensuring enhanced stability, control, and comfort.

This technology optimizes aerodynamics by smart control of the vehicle ride-height, and increases energy efficiency, making it essential for both electric and internal combustion vehicles. Once limited to luxury and heavy-duty models, air suspension is now also being adopted for larger volume models, providing lighter, and high-performing solutions that meet evolving automotive demands. The larger production volumes also create the need for highly cost-effective material solutions, as well as manufacturing methods for the air springs. 

Innovating for a sustainable automotive future

Envalior is leading the transformation of air suspension systems by replacing heavy metal components with advanced plastics, improving performance, weight reduction, and manufacturing efficiency. Through strategic collaborations with Tier 1 suppliers and OEMs, we provide end-to-end support—from material selection and CAE analysis to prototyping and production—ensuring future-ready solutions that meet the automotive industry's evolving needs.

Sustainability is at the heart of our innovation. Our bio-based and recycled materials significantly lower carbon footprints, helping manufacturers meet regulatory requirements, enhance efficiency, and reduce emissions. As air suspension expands beyond luxury vehicles into mainstream automotive platforms, Envalior remains at the forefront—delivering lighter, stronger, and more sustainable materials that redefine mobility for a greener future.

ADVANCED MATERIALS FOR SMARTER, STRONGER SUSPENSION

Traditional metal components add weight, complexity, and cost, limiting design flexibility and efficiency. Envalior’s high-performance plastics—Akulon® (PA6), Durethan® (PA66)—replace metal in key air spring components, delivering lightweight strength, durability, and superior NVH (Noise, Vibration, and Harshness) control for a smoother, quieter ride. Envalior’s Arnitel ® (TPC), can be used for the flexible components, like bellows and gaiters, providing a more sustainable thermoplastic solution to replace the traditional, vulcanized materials. 

Beyond performance, our bio-based and recycled materials help reduce carbon footprints, enabling sustainable and cost-effective manufacturing. With seamless processability and integrated functionalities, Envalior’s innovations are powering the next generation of air suspension—lighter, stronger, and more efficient than ever before.
