Front Leaf Spring 2nd Blade WG9725520077+02 for Sinotruk HOWO Heavy Duty Truck

This front leaf spring second blade (also known as the 2nd leaf or secondary leaf) with part number WG9725520077+02 is specially designed for Sinotruk HOWO heavy duty trucks. It is a critical component of the front suspension system, working together with the main leaf and other leaf springs to absorb road shocks, support vehicle weight, and maintain proper ride height and axle alignment.

Made of high-quality spring steel with precision heat treatment and shot peening, this leaf spring blade features excellent fatigue resistance, high tensile strength, and long service life. The precise arc shape and thickness are engineered to provide the correct spring rate and load distribution when assembled in the complete leaf spring pack. The durable construction is specifically engineered to withstand the constant flexing, heavy loads, and harsh road conditions encountered in heavy duty truck applications.
