Heavy/Light/Small Duty Boat/Semi/Dump Trailer Leaf Spring for Truck/Camper/Caravan/Farm/Agricultural Vehicle/Tipper Lorry

Product Description

Function of Vehicle Leaf Springs
A leaf spring is made up of multiple elastic steel plates of equal width but different lengths. Its main function is to connect the vehicle frame and axle as part of the suspension system. Positioned between the frame and the axle, the leaf spring supports the load transmitted from the wheels, absorbs and reduces road shock and vibration, helps maintain vehicle stability, and improves adaptability to different road conditions.
