Import Auto Spring For Nissan — Buy in Bulk from Supplier in China

This coil spring is manufactured for Nissan vehicle suspension systems, designed to restore or upgrade ride height and handling characteristics per OEM replacement standards. Yutian Hengtong Spring Shock Absorber Co., Ltd produces this component from their facility in Tangshan, China, with material specification and spring rate calibrated for Nissan passenger car and light truck applications. The spring is cold-formed from alloy steel wire, with shot peening applied to enhance fatigue resistance. Surface treatment follows automotive industry protocols for corrosion protection in varied climate conditions. Each unit is dimensionally checked against Nissan fitment tolerances to ensure direct replacement without modification. The supplier indicates availability across multiple Nissan model years, though buyers should confirm exact vehicle application before ordering.

The material grade is typically SAE 9254 or equivalent silicon-manganese spring steel, a standard specification for automotive coil springs requiring high static fatigue strength and resistance to permanent set. Wire diameter, active coil count, and free length are engineered to produce the specified spring rate for each Nissan application. A typical tensile strength range of 1800-2100 MPa applies to this material class after heat treatment. The shot peening process induces compressive residual stresses at the surface, extending operational life under cyclic loading. Powder coating or epoxy-based finish provides the primary corrosion barrier, with salt spray resistance typically rated at 500 hours minimum per ASTM B117 for comparable automotive springs. Heat treatment follows the standard quench and temper sequence to achieve the required hardness of approximately 45-50 HRC.

Buyers for this product include automotive aftermarket distributors, independent repair chains, and vehicle refurbishment operations serving Nissan fleets. The spring suits both routine maintenance replacement and suspension upgrade programmes where restored spring performance is required. Trade terms require direct confirmation with Yutian Hengtong, as published MOQ, pricing, and lead time figures are not available in the source data. Packaging typically comprises individual polybag protection with carton consolidation for shipment. Incoterms and payment structures should be negotiated directly, with common arrangements in this sector including FOB Tianjin or CIF destination port, with documentary credit or telegraphic transfer payment. Buyers should request material certification and dimensional inspection reports with each shipment.

Yutian Hengtong Spring Shock Absorber Co., Ltd operates from Xingyu Industrial Park in Tangshan, Hebei Province, China, with postal address 064100. The supplier is classified as an imported-tier vendor with harbour trust tier on the platform, indicating a baseline verification status rather than enhanced supplier standing. The response rate is recorded at 0.00 percent with zero average response hours, which suggests delivery should not be assumed until buyer communication is successfully established. No employee count, annual revenue, year of establishment, or specific factory floor space is stated in the available profile data.

The company's product focus centres on spring and shock absorber manufacturing for automotive applications, with this Nissan-specific coil spring representing their aftermarket and replacement component line. The listing does not indicate ISO certification, IATF 16949 automotive quality system registration, or third-party laboratory accreditation. Buyers should request quality system documentation and sample evaluation before committing to volume orders. The Tangshan location places production within China's northern industrial corridor, with established logistics routes to Tianjin Port for export shipment. Direct engagement with the supplier is essential to confirm production capacity, current order backlog, and export experience to specific destination markets.
