Parabolic Leaf Spring 9433200402 For Mercedes Benz Heavy Truck Air Suspension

Our parabolic leaf spring 9433200402 is engineered as a guide component for Mercedes-Benz air suspension systems, widely fitted on heavy-duty trucks and buses.

Unlike conventional multi-leaf springs, this parabolic leaf spring adopts tapered variable cross-section design, which reduces weight while maintaining outstanding mechanical performance. It mainly undertakes longitudinal force and axle positioning, working together with air bags to deliver stable driving performance.
