Trailer Leaf Spring
Leaf spring
Model Number:90-11-13
Leaf springs are made of multiple layers of steel plates stacked together. When the vehicle is in motion, the spring flexes to absorb road impacts and distribute load evenly, ensuring stability and ride comfort.
Applications
• Semi trailers
• Truck suspension systems
• Agricultural trailers
• Heavy-duty transport vehicles
