COMPOSITE LEAF SPRINGS FOR TRACTOR OEMs.Liteflex is the only company in the world to successfully manufacture composite Class 8 steer axle leaf springs and has provided continuous serial production since 1994. Our springs meet current MVSS standards and are 50%-75% lighter than traditional springs, improving fuel economy and payload capacity. They are corrosion resistant and 3.5 times more durable than steel.

Liteflex has updated existing composite steer axle leaf springs to meet the new FMVSS 121 requirements. They feature our patented brake wind-up preventer (US Patent 9,016,705) to ensure safe and reliable handling during hard braking, and require no tooling costs.

Currently available on the Volvo VNL, our springs have also been noted to significantly improve tire wear for some drivers [See: Lightweight Composite Springs Double Tire Life]. They provide 50 percent more vibration damping to improve ride quality and feature a “drive home” capability in the unlikely event they become damaged. Liteflex Composite Springs are a proven option for manufacturers around the globe.
