Import Air Suspension Shock — Buy in wholesale FOB from Supplier in China

This front air suspension shock absorber pair is produced by Rarelong Auto Parts Technology Co., Ltd for Mercedes-Benz W220 S-Class chassis applications. The assembly combines rubber air bellows, steel structural components and aluminum machined parts to replace failed original equipment dampers. OE cross-reference numbers are A2203202438, A2203205113, A2203202138 and A2203202238, covering front left and front right positions. The unit is supplied as an aftermarket replacement with stated 12-month warranty coverage and compatibility limited to the W220 platform generation.

Material construction centres on a multi-ply rubber air spring for variable ride height control, supported by steel coil or structural elements for lateral location, and aluminum for the piston and top mount where weight reduction and corrosion resistance matter. The rubber compound must resist ozone, hydraulic fluid and temperature cycling between -40 degrees C and +80 degrees C typical for underbody automotive exposure. Gas charging and damping valving are internal to the strut body; the listing does not specify whether mono-tube or twin-tube architecture is used, so buyers should request the damping curve or velocity diagram for the specific part number.

Target buyers are independent Mercedes-Benz specialists, high-end independent workshops and auto parts distributors serving the W220 installed base, which remains significant in secondary markets. The supplier is based in Guangzhou with harbour trust tier status but zero recorded response rate. Lead time is statedemplated as 1-3 working days for stocked items after payment clearance, though stock availability must be confirmed directly. Payment options include T/T, Western Union, PayPal and cash. Shipment is offered by air, sea, or express courier including DHL, FedEx, UPS and TNT. Packaging comprises a safe inner box within a standard outer carton.

Rarelong Auto Parts Technology Co., Ltd is located in Guangzhou, China. The supplier holds a harbour trust tier on the platform. The response rate is recorded at 0.00 percent with no average response hours logged, meaning buyers have no message-response track record to evaluate. Direct communication is therefore essential to gauge current operational status and support capability before committing to volume orders.

The company markets under its own Rarelong brand and focuses on Mercedes-Benz W220 air suspension components, specifically offering this front shock absorber pair. No information is provided about year of establishment, factory floor space, employee count, annual turnover, ISO certification status, or named OEM or aftermarket clients. The listing does not indicate whether Rarelong manufactures the shocks in-house or sources from a third-party facility. Buyers should request factory audit reports, current quality system certification, and batch test documentation to assess production control.
