55360-3T500  55360-3T501 Rear Right Air Spring Bag for KIA K9 / K900, Hyundai Equus

Installation Position: Exclusive for rear right air suspension. Dedicated to rear right position, non-universal for rear left and front position. Only suitable for original air suspension models, not compatible with mechanical suspension and other ordinary Hyundai/KIA models.

Product Description: The 55350-3T500 / 55350-3T501 air spring is a dedicated rear right air suspension assembly for Hyundai and KIA high-end flagship Korean sedans. Custom-molded for the rear right load-bearing structure of the vehicle, it adopts a multi-layer thickened weather-resistant and explosion-proof rubber structure with high-density tensile woven cords, integrated molded sealing ports and anti-corrosion wear-resistant base. It is a complete integrated assembly with no secondary processing or old parts reuse required. It can directly replace the aging, leaking and collapsed original rear right air spring, perfectly matching the original vehicle air suspension control system and exclusive rear right mounting points and pipeline structure.

• 1:1 original mold replication strictly based on OE data, precisely matching the rear right mounting holes, bladder stroke, pressure parameters and sealing caliber. No pipeline or bracket modification required during installation, featuring perfect fitting, no air suspension fault codes and accurate rear right vehicle height calibration
• Optimized for the heavy curb weight and high rear-right load of K9 and Equus luxury sedans. Resistant to strong sunlight, extreme cold and high-pressure fatigue deformation, it completely solves common rear right air suspension problems: static slow air leakage, single-side sinking, right tilt under load and loose chassis abnormal noise on bumpy roads
• Upgraded high-strength multi-layer warp and weft cords deliver far better tensile, explosion and aging resistance than ordinary aftermarket parts. No delamination, bulging or cracking under long-term high pressure, eliminating repeated leakage and rework with service life close to original factory level
• Original-grade integrated sealing technology resists high and low temperature erosion and prevents slow pressure relief. Stable performance adapts to all seasons, maintaining uniform pressure and strong support, and fully restoring the original adaptive air suspension comfort and automatic vehicle leveling function
• Direct assembly replacement solution thoroughly repairs structural faults of original rear right air spring including rubber aging, bladder cracking, layered damage, micro air leakage, rear right sinking, unbalanced vehicle height and occasional air suspension alarm
• Every product undergoes strict factory tests including high-pressure air tightness test, heavy-load pressure resistance test and high & low temperature weathering aging test. With stable quality and high consistency, it is ideal for 4S official maintenance, professional luxury car repair, high-end used car renovation, cross-border bulk stocking and full-container foreign trade orders

55350-3T500 and 55350-3T501 are original iterative dedicated air suspension parts for Hyundai and KIA high-end flagship models, exclusively applicable to the rear right position of original air suspension equipped KIA K9/K900 and Hyundai Equus/Genesis. As heavy luxury sedans, these models bear large rear load. The original rear right air spring is prone to rubber aging & hardening, bladder cracking, layered bulging and sealing failure due to long-term high-frequency bumping, continuous high-pressure load and alternating seasonal temperature erosion.

Typical vehicle faults include rear right sinking after parking, right vehicle tilt under load, rear right floating at high speed, chassis abnormal noise when crossing speed bumps and air suspension fault light warning. Minor surface air leakage can be temporarily repaired with repair kits, but structural damage such as bladder deformation and layered bulging cannot be fundamentally fixed. Replacing with a brand-new dedicated rear right air spring assembly is the most stable, cost-effective and low-rework maintenance solution at present.

Manufactured in strict accordance with original factory rear-right exclusive parameters, craftsmanship and dimensions, this product is fully compatible with the original vehicle air suspension control system and supports non-destructive in-situ installation without any pipeline or bracket modification. After installation, only air tightness testing, rear right vehicle height calibration and fault code clearing are required to fully restore the original chassis support performance and adaptive height adjustment function.

• KIA: K9 / K900｜All original factory air suspension versions (2012–2019, Rear Right Exclusive)
• Hyundai: Equus / Genesis｜All original factory air suspension versions (Rear Right Exclusive)

Product Features: Exclusive accessory for luxury flagship sedans (rear right), heavy-load resistant, aging & weather resistant, stable air tightness and low rework rate, suitable for professional luxury car maintenance, used car renovation, cross-border bulk export and full-container foreign trade orders

Remark: The above OE numbers are original upgraded replacement parts with 100% consistent structure, dimensions, pressure parameters, mounting holes and sealing specifications for rear right position, supporting direct non-destructive interchangeable replacement.

Q1: Can 55350-3T500 / 3T501 rear right air spring be used for rear left position?

A: No. This is an exclusive rear right air spring. The rear right and rear left air springs have different base angles, mounting points and pipeline matching structures. Left and right parts are strictly distinguished and cannot be interchanged or mixed installed.

Q2: Can it be installed on front air suspension or rear left position?

A: No. The front and rear air suspension structures of K9 and Equus are completely different. The front suspension adopts integrated shock struts while the rear suspension adopts independent air springs. Besides, rear left and rear right air springs are not universal with different strokes, pressure resistance and mounting points. Mixing installation is strictly prohibited.

Q3: Is it suitable for mechanically suspended K9/Equus?

A: No. This product is dedicated to air suspension. Mechanical suspension models are not equipped with air suspension inflation systems, dedicated pipelines and mounting bases, resulting in no compatibility.

Q4: Can OE numbers with different suffixes replace each other?

A: Yes. Original iterative models including 3T500, 3T501, 3M500 and 3M501 share identical parameters, dimensions and performance for rear right position, supporting direct non-destructive replacement.

Q5: When is it necessary to replace the rear right air spring assembly?

A: Replacement is recommended when the rear right air spring has bladder cracking, layered bulging, rubber hardening & aging, slow air leakage after parking, rear right sinking, obvious left-high & right-low vehicle height deviation, or repeated pressure leakage after repair kit maintenance, to eliminate faults completely at one time.

Q6: Is computer programming required after replacement?

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

Q7: Is this rear right air spring universal for K9 and Equus?

A: Yes. The two luxury flagship models adopt the same rear air suspension structure, and this product is universally applicable to the rear right position of both models for interchangeable replacement.
