Description
AZ9125520268 rear spring riding bolt (U-bolt) is an important fastening spare part of Sinotruk Howo heavy truck rear suspension system. It fastens the rear leaf spring firmly onto the rear axle housing, transferring vertical load and resisting impact force during heavy load driving. This riding bolt is forged from high-strength alloy steel and processed by quenching, tempering and surface anti-corrosion treatment. It has high tensile strength, good toughness and strong fatigue resistance, which can withstand long-term vibration and alternating load under heavy haul and bumpy road conditions. Each U-bolt undergoes strict tensile test, hardness inspection and thread tolerance detection before delivery to prevent bolt elongation, thread slipping and fracture. It is an essential replacement part for rear suspension maintenance and overhaul. We maintain sufficient inventory and stable bulk supply for repair workshops, fleet operators, auto spare parts dealers and global cross-border export customers.
