55350-3M501 55360-3M501 Rear Left Air Spring Bag for Hyundai Equus

55350-3M501 55360-3M501 Rear Left Air Spring Bag for Hyundai Equus

• Precisely matched with original OE 55350‑3M501 / 55360‑3M501, specially developed for Hyundai Equus original rear air suspension. Separate left/right design with 1:1 original factory reproduction of mounting holes, sealing caliber and inflation stroke, ensuring perfect fitting and no air suspension fault codes after installation
• Upgraded thickened explosion-proof rubber bladder, optimized for luxury sedan rear load, urban bumpy roads, high-speed driving and alternating seasonal temperatures. Anti-aging, anti-cracking and anti-leakage, thoroughly solves common Equus rear air suspension problems: rear end sinking after parking, slow air leakage, one-sided low rear height, rear suspension abnormal noise and pressure relief sagging
• Fully reproduced original parameters including maximum pressure resistance, installation height and interface size. Supports direct in-situ installation without grinding or pipeline modification, ensuring stable vehicle level and reliable air suspension operation
• Reinforced internal load-bearing cords with excellent anti-fatigue and anti-tensile performance, effectively avoiding common defects of ordinary aftermarket parts such as short-term bulging, cracking and air leakage, greatly reducing rework rate, ideal for luxury car maintenance and used car renovation
• Professional assembly replacement solution for structural damages including rubber aging & cracking, bladder bulging & deformation, body tearing, continuous micro air leakage and repeated failure after repair kit maintenance, realizing one-time thorough repair
• 100% factory inspection including high-pressure air tightness test, fatigue sampling test and weathering aging test to eliminate defective leakage products, perfectly restoring original rear support, vehicle level and air suspension damping comfort

55350‑3M501 (Rear Left) and 55360‑3M501 (Rear Right) are original factory matching rear air spring models for Hyundai Equus. Compatible with 2011‑2016 Hyundai Equus rear air suspension systems, they are high-frequency vulnerable parts for Korean flagship luxury sedan air suspension, widely used in repair shop maintenance, used car renovation, luxury car finishing and cross-border replacement procurement.

The original Hyundai Equus is equipped with adaptive rear air suspension. After long-term use, the rear air spring bears continuous pressure from vehicle weight and trunk load, as well as road vibration and alternating cold and hot weather. This easily causes rubber aging & hardening, cord fatigue, sealing port micro-leakage and base sealing failure, leading to typical faults: rear end sinking after parking, static slow air leakage, uneven left-right vehicle height, rear suspension bump noise, air suspension alarm and abnormal height locking.

When the air spring suffers structural damage that cannot be completely repaired by repair kits, replacing the full assembly is the most reliable and long-term maintenance solution. Manufactured in strict accordance with original factory processes, sealing and pressure parameters, this product perfectly matches the original rear air suspension control system and supports non-destructive in-situ installation without chassis cutting or pipeline modification. After installation, air tightness testing, body height calibration and fault code clearing can fully restore the original air suspension performance and driving texture.

Product Features: Vehicle-specific rear air spring with stable air tightness and excellent aging resistance, suitable for luxury car repair & renovation, professional maintenance, cross-border bulk stocking and full-container foreign trade orders

Remark: The above OE numbers are original iterative universal parts with 100% consistent structural size, pressure resistance parameters and mounting base, universally applicable to 2011‑2016 Hyundai Equus rear air springs.

• Q1: Can 55350‑3M501 and 55360‑3M501 be interchanged left and right?

  A: Not interchangeable. 55350‑3M501 corresponds to the rear left side and 55360‑3M501 corresponds to the rear right side. Different base and interface structures will cause assembly failure, incorrect vehicle height and air suspension fault codes if mixed installed.

• Q2: Can it be installed on the front suspension?

  A: No. The front and rear air springs of Equus have completely different stroke, base and pressure parameters. Strictly non-universal, wrong installation is prohibited.

• Q3: Is it suitable for mechanically suspended Equus models?

  A: No. This product is dedicated to air suspension systems. Mechanical suspension models have no air suspension pipelines, inflation systems or air spring mounting bases, resulting in no compatibility.

• Q4: Can 55350‑3M500 and 55360‑3M500 be directly replaced?

  A: Yes. They are original upgraded iterative numbers with identical structure, performance and installation dimensions, plug-and-play.

• Q5: When is full assembly replacement required?

  A: Assembly replacement is recommended when the air spring has rubber cracking & hardening, bladder bulging & deformation, body tearing, continuous slow air leakage or repeated failure after repair kit maintenance, to solve faults thoroughly at one time.

• Q6: Is computer programming required after replacement?

  A: No complex programming required. Only air tightness testing, body height calibration and air suspension fault code clearing are needed after installation for normal operation.

• Q7: Is it universal for 4.6L and 5.0L Equus?

  A: Fully universal. All 2011‑2016 Equus 4.6L and 5.0L air suspension versions share the same rear air spring structural parameters.
