Features and Benefits — Why Procurement Managers Choose This Sinotruk U-Bolt

Superior Material Strength

Forged from premium-grade carbon steel, the AZ9725520053 U-bolt withstands the torsional and tensile stresses common in heavy-haul applications. The material composition matches Sinotruk OEM specifications, ensuring direct fitment without modification.

Black Anti-Corrosion Surface Treatment

A factory-applied black oxide coating protects against moisture, road salt, and chemical exposure. This extends service life in tropical, coastal, and winter operating environments — reducing replacement frequency and total cost of ownership for your customers.

Precision-Threaded Hex Nuts Included

Each U-bolt ships with two precision-machined hexagonal nuts, eliminating the need to source matching hardware separately. Thread tolerances are held tight to ensure consistent torque application and vibration resistance.

Direct OEM Replacement

Part number AZ9725520053 is a direct-fit replacement for Sinotruk HOWO suspension systems. No drilling, welding, or bracket modification required — this cuts installation time and labor costs at the workshop level.

Bulk Supply Consistency

Mettlead maintains batch-to-batch dimensional consistency through CNC-controlled production and statistical quality sampling. When you order 500 or 5,000 pieces, every U-bolt meets the same dimensional and hardness specifications.
