Precise Thread Leaf Spring U Bolt High Tensile Strength Anti Rust for Fleet Truck

The Leaf Spring U Bolt is a heavy-duty clamp that holds the leaf spring firmly to the axle of a truck, so that the spring cannot shift under load. It is produced to original equipment specification and installs on the original mounting points.

Every U bolt is made from high-strength alloy steel that is quenched and tempered for high tensile strength, so it resists breakage even when a fully laden truck runs over rough ground. The precise thread machining gives a good match with the nuts, which means no slipping after long-time bumpy driving, and the anti-rust surface treatment provides corrosion resistance for muddy and wet road conditions.

By firmly locking the leaf spring, the U bolt prevents spring displacement and keeps the suspension geometry correct, which improves driving safety and extends the life of the spring. Full model coverage is available for heavy-duty and light-duty trucks, both domestic and imported, and customization and OEM production are offered for your own dimensions, thread and material requirements.

• High Strength Alloy Steel: Made from high-strength alloy steel, quenched and tempered for high tensile strength, so the U bolt does not break even under heavy load.
• Precise Thread Machining: Precise thread machining gives a good match with the nuts, so there is no slipping even after long-time bumpy driving.
• Anti Rust Surface Treatment: The anti-rust surface treatment gives reliable corrosion resistance for muddy and wet road conditions.
• Firmly Locks the Leaf Spring: The U bolt firmly locks the leaf spring and prevents spring displacement, which improves driving safety.
• Full Model Coverage: Full model coverage for heavy-duty and light-duty trucks, both domestic and imported, for easy one-stop sourcing.
• Customization and OEM Service: Customization and OEM production are available to match your own dimensions, thread and material specifications.

The leaf spring U bolt is used on the suspension of heavy-duty and light-duty trucks, including tractor units, dump trucks, tippers, trailers and long-haul trucks, on both domestic and imported vehicles. It is the correct replacement for a stretched, corroded or broken U bolt, and it is chosen by fleets, transport companies and repair workshops that want a safe, rattle-free and durable spring mounting.

Every U bolt is packed in a neutral export carton with the size on the label, so that the threads and the bent body arrive free from damage and can be picked and stored easily. Nuts can be supplied with the U bolts on request, and OEM cartons and private labels are available. All units are produced to original equipment specification and inspected before shipment, and full technical support and fitting advice are provided. Mixed containers are welcome for distributors and repair workshops. Please contact us for samples, volume discount pricing and confirmed lead times.
