55350-3T500 55350-3T501 Rear Left Air Spring for KIA K9 / K900 & Hyundai Equus / Genesis

• Precisely matched with original OE 55350-3T500 / 55350-3T501, 1:1 original mold replication exclusively for KIA K9 and Hyundai Equus rear left air suspension system. Pressure parameters, bladder stroke, mounting holes and sealing caliber fully match the original rear left position, ensuring zero installation error, stable air tightness, no fault codes and accurate rear left body height restoration
• Optimized for luxury sedans with heavy curb weight and large rear load, adapting to urban and long-distance driving conditions. Resistant to strong sunlight, extreme cold and fatigue deformation, it thoroughly solves common rear left air suspension problems: rear left body sinking, static slow air leakage, load pressure relief, left-right body tilt and loose chassis abnormal noise when crossing speed bumps
• Upgraded multi-layer high-density warp and weft cords provide far better tensile, pressure and aging resistance than ordinary aftermarket parts. No delamination, bulging or cracking under long-term high pressure, effectively avoiding short-term air leakage and repeated rework, with service life close to original factory level
• Original-grade integrated sealing technology prevents port hardening and slow pressure relief under high and low temperatures. Adaptable to all-season temperature changes, it maintains stable pressure and uniform support, perfectly retaining the original high-end air suspension comfort and adaptive height adjustment performance
• Direct assembly replacement solution completely repairs structural failures of original rear left air spring including rubber aging, bladder cracking & damage, layered bulging, continuous micro air leakage, rear left sinking, unbalanced body height and occasional air suspension alarm, realizing long-term one-time repair
• Every product undergoes strict factory tests including high-pressure air tightness test, heavy-load pressure resistance sampling test and high & low temperature weathering aging test, fully complying with original factory standards. Featuring stable quality and ultra-low rework rate, it is ideal for luxury vehicle 4S maintenance, high-end used car renovation, professional repair shop service and cross-border bulk export

55350-3T500 and 55350-3T501 are original iterative universal air suspension parts for Hyundai/KIA high-end luxury models, exclusively applicable to the original rear left air suspension system of KIA K9 (K900) and Hyundai Equus / Genesis. As a core high-frequency vulnerable part of the rear left air suspension system for Korean luxury flagship sedans, it is widely used in original vehicle maintenance, high-end used car refinement, professional precision repair and cross-border auto parts bulk replacement.

KIA K9 and Hyundai Equus are top flagship luxury sedans equipped with original adaptive rear air suspension. Due to heavy vehicle weight and large rear passenger load, the original rear left air spring is continuously impacted by high-frequency road bumps, long-term heavy pressure, high-temperature sun exposure in summer and low-temperature erosion in winter. It is prone to rubber aging & hardening, bladder cracking, layered bulging, sealing port pressure relief and chronic air leakage, causing common problems such as rear left body collapse after parking, low left vehicle body, rear floating at high speed, chassis abnormal noise and air suspension fault light warning.

When the original rear left air spring has structural damage, deformation or continuous air leakage that cannot be completely repaired by repair kits, replacing a brand-new assembly is the most stable, low-rework and cost-effective maintenance solution. Manufactured in strict accordance with original factory technology, pressure parameters, bladder stroke and exclusive rear left mounting points, this product is fully compatible with the original vehicle air suspension control system, supporting non-destructive in-situ installation without pipeline or bracket modification. After installation, only air tightness testing, rear left body height calibration and fault code clearing are required to completely restore the original rear air suspension supporting performance and luxury driving texture.
