OE Number: 68029912AE

Product Type: Air Spring Bag Assembly (complete air bag, excluding damper core)

Mounting Position: Rear Suspension‑ Left / Right Side (Universal for Left & Right)

Structure: Multi‑layer reinforced anti‑aging rubber air bag body with integrated upper and lower connecting bases, complete sealing structure. Designed for vehicles with intact original damper core. Directly replace the damaged rear air spring bag and reuse original damper core, no need to replace complete air strut assembly. Perfectly compatible with factory Quadra‑Lift air suspension system to restore vehicle height adjustment and auto‑leveling function.

• Adopts high weather‑resistant composite rubber material, ozone‑proof and anti‑aging. Tolerate wide temperature range, rain, snow and sand road conditions, reduce risks of bag folding crack and slow air leakage, ideal for SUV rough road usage.
• 1:1 OEM molding, identical dimension, stroke, interface and mounting base with original parts. No modification required, direct fit for original intact rear damper core.
• Every unit passes high‑pressure air tightness & pressure holding test before delivery, avoid factory leakage, stable replacement performance.
• Much lower repair cost than full air strut assembly. If original damper is in good condition, only replace air spring bag to fix suspension failure and cut customer maintenance expense.
• Complete air bag assembly with built‑in base sealing structure, simple installation, no extra spare parts required, ready for workshop direct mounting.

• Rear body sinks on one or both sides after vehicle parking
• Air suspension malfunction warning light illuminates on dashboard
• Air compressor frequent cycling, continuous running, overheating and increasing noise
• Uneven rear body height, vehicle tilting and poor driving stability
• Cracks or pinhole slow leakage on rubber folding area of air bag
• Damper core without oil leakage, only air spring bag is leaking and damaged (suitable for this replacement part)

Notice:

1. This rear air spring bag is universal for rear left and rear right, no left‑right distinction.
2. If damper core oil leakage, damping failure or cylinder deformation occurs, replacing only air bag is not recommended, complete air strut assembly shall be changed.

A: Choose this air spring bag if damper core is oil‑free and works well while only air bag cracks and leaks. Replace complete air strut assembly when damper core oil leakage, cylinder deformation or damping failure happens.

A: If only air bag leaks and compressor works normally, just replace air spring bag. If compressor works overload with abnormal noise and overheating, inspect or replace compressor to extend whole suspension service life.

A: Yes. Special diagnostic tool must be used to perform body height calibration after air bag installation. Without calibration, body height deviation and suspension fault codes will appear.

A: 12‑month standard warranty. Covers natural aging crack and slow air leakage under normal usage. Damage caused by collision, improper installation, chassis scratch or modification is excluded from warranty.

A: ① Check original suspension configuration via 17‑digit VIN code; ② Disassemble original air bag, verify stamped OE number and confirm damper core without oil leakage.
