Quanzhou Zhongke Autoparts — Reliable Manufacturer of High-Strength U-Bolts

Product Description

U-bolts play a crucial role in leaf spring suspension systems. They securely attach the leaf spring to the axle of the vehicle, maintaining proper axle positioning, driveline angles, and overall suspension geometry. The unique “U” shape, with threaded arms on both sides, helps resist vibrations and impacts during high-stress operations, making them indispensable in heavy-duty trucks, trailers, and off-road equipment.

Zhongke’s U-bolts are manufactured using high-quality materials such as 40Cr and 45# steel. These materials offer outstanding mechanical strength and fatigue resistance. Our U-bolts undergo a series of precision manufacturing steps including hot forging, thread rolling, heat treatment, and surface finishing. We offer a variety of surface treatments like zinc plating, black oxide, phosphating, electrophoresis, and Dacromet coating to enhance corrosion resistance and extend product lifespan.

Each product is rigorously inspected before shipment to ensure compliance with international quality standards. We also provide complete customization services based on customer drawings or samples. Whether for OEM use or aftermarket replacement, Zhongke U-bolts deliver exceptional performance and cost-effectiveness.
