Core Selling Points

• 1:1 original OE precise replication, strictly compliant with Xpeng original 3340300EE3-00-01 parameters. Bladder stroke, pressure resistance value, mounting holes and sealing caliber fully match Xpeng G9 and X9 original vehicles. Specially calibrated for dual-chamber air suspension system ensures perfect fitting, no fault codes and accurate rear body height calibration
• Optimized for Xpeng G9/X9’s heavy pure electric curb weight, battery chassis load, frequent urban start-stop, high-speed cruising and large seasonal temperature differences. Enhanced resistance to low temperature, strong sunlight and heavy-load extrusion deformation thoroughly solves common Xpeng rear air suspension faults: static slow air leakage, single/double-side sinking, body tilt, loose chassis abnormal noise over bumps and unstable rear floating at high speed
• Upgraded high-density warp and weft tensile cords adapt to long-term high-pressure load and high-frequency shock absorption characteristics of Xpeng flagship models. Superior anti-fatigue, anti-delamination and anti-cracking performance outperforms ordinary aftermarket parts, eliminating short-term air leakage and repeated rework with greatly extended service life
• Original-grade integrated sealing technology with high and low temperature hardening treatment prevents slow pressure relief caused by seasonal temperature changes, maintaining stable pressure in extreme cold and heat. It fully restores the original Xpeng intelligent air suspension damping texture and automatic body leveling function
• Direct assembly replacement fundamentally solves structural faults of original rear air spring for Xpeng G9/X9, including rubber aging, bladder cracking & damage, layered bulging, continuous micro air leakage, rear sinking, unbalanced body height and intermittent air suspension alarm, achieving long-term stable repair with ultra-low rework rate
• 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 in line with Xpeng new energy factory standards. Featuring stable quality and high consistency, it is ideal for Xpeng 4S maintenance, high-end used car renovation, professional repair shops and batch stocking

Product Description

3340300EE3-00-01 is a high-frequency vulnerable original factory air suspension part for Xpeng flagship models, with supporting factory model HH-AR3705-001_C, exclusively applicable to all original air suspension versions of Xpeng G9 and Xpeng X9. As high-end pure electric flagship vehicles, Xpeng G9 and X9 have heavy curb weight and large-capacity chassis batteries bearing long-term heavy load, equipped with original dual-chamber intelligent air suspension that balances comfort and sporty chassis tuning. The original rear air spring operates under long-term high-frequency expansion & contraction, high-pressure load, high-speed bumping and alternating seasonal temperatures, which easily leads to rubber aging & hardening, bladder cracking, layered bulging, sealing failure and chronic air leakage.

Typical daily faults include rear body sinking after static parking, single-side collapse, body tilt under load, unstable rear floating at high speed, chassis abnormal noise over bumpy roads and occasional air suspension alarm under high temperature conditions, making it a core high-frequency maintenance part for Xpeng G9 and X9. Minor surface air leakage can be temporarily repaired with repair kits, but structural bladder deformation, layered damage and high-temperature pressure relief failure cannot be completely fixed. Replacing with this original-grade upgraded rear air spring assembly is currently the most stable and cost-effective maintenance solution for Xpeng G9/X9 air suspension faults.

Manufactured in strict accordance with Xpeng G9/X9 original factory technology, pressure parameters, bladder stroke and mounting points, this product is fully compatible with Xpeng original dual-chamber intelligent air suspension control system, supporting non-destructive in-situ installation without pipeline or bracket modification. After installation, only air tightness testing, rear body height calibration and fault code clearing are required to completely restore the original rear air suspension support performance, damping texture and intelligent leveling function, thoroughly solving the common faults of original rear air springs for Xpeng G9/X9.

Important Notice: This product is an exclusive rear air spring for Xpeng G9 and X9, universal for rear left and rear right, non-universal for front. Only applicable to models equipped with original dual-chamber intelligent air suspension, not available for mechanical suspension vehicles, other Xpeng models and non-Xpeng vehicles.

1. XPEV Xpeng: G9 all original air suspension versions, X9 all original air suspension versions (Universal rear replacement part)

Product Features: Exclusive for Xpeng flagship pure electric vehicles, compatible with dual-chamber air suspension system, heavy-load resistant, aging & weather resistant, stable air tightness and low rework rate, ideal for Xpeng 4S new energy maintenance, high-end used car renovation, professional luxury car repair shops, batch stocking and foreign trade orders

Q1: Is this air spring universal for Xpeng G9 and X9?

A: Yes. This product is fully compatible with all air suspension versions of Xpeng G9 and X9. The rear air spring parameters, dimensions and mounting points of the two models are completely consistent and interchangeable.

Q2: Are rear left and right air springs universal? Can they be installed on the front axle?

A: The rear left and right are completely universal with no need to distinguish left or right. The front and rear air suspension structures, strokes and pressure resistance parameters are vastly different. Installation on the front axle is strictly prohibited, which will cause incompatibility and fault codes.

Q3: Is it suitable for mechanically suspended Xpeng G9/X9?

A: No. This product is a dedicated air suspension assembly. Mechanical suspension models are not equipped with air suspension inflation systems, dedicated pipelines and mounting bases, so installation is not supported.

Q4: Will it trigger air suspension fault codes after installation? Is programming required?

A: This product adopts 1:1 original parameter replication and is fully compatible with Xpeng dual-chamber air suspension system without complex programming matching. Only air tightness test, body height calibration and fault code clearing are required after installation for normal use with no errors or compatibility issues.

Q5: What faults require replacement of this rear air spring?

A: Replacement is recommended if the vehicle has rear sinking after overnight parking, single-side body collapse, body tilt under load, chassis abnormal noise over bumpy roads, unstable rear driving at high speed, occasional air suspension fault lights, aging & cracked air springs, chronic micro air leakage, or repeated air leakage after repair kit maintenance.

Q6: Is it only suitable for dual-chamber air suspension? Does it fit single-chamber versions?

A: This product is exclusively customized for Xpeng G9/X9 original dual-chamber intelligent air suspension system, precisely matching dual-chamber configurations and incompatible with single-chamber air suspension. Please confirm the vehicle suspension configuration before ordering and installation.

Q7: What is the difference between this aftermarket part and the original factory part?

A: This product is manufactured in strict accordance with original factory technology and testing standards, replicating original pressure bearing, pressure maintaining and stroke parameters. The upgraded thickened tensile cords deliver better aging resistance and pressure relief resistance than ordinary aftermarket parts, compatible with original vehicle system without fault codes, with much higher cost performance than original parts.
