23116448 22907781 Rear Air Spring Bag For Cadillac XTS 2013‑2019
Product Info | OE: 23116448
Product Name: Rear Air Spring Bag
Important Note: Complete rear air spring bag assembly, without shock absorber damper core. Universal for rear left and rear right side, interchangeable.
1. Product Introduction
OE Number: 23116448
Product Type: Air Spring Bag Assembly (without damper core)
Structure: Multi‑layer reinforced weather‑resistant rubber with high‑strength plastic sealing bases. Replace the worn‑out leaking air bag while reusing original intact damper core, no need to replace full strut assembly. Matches factory air suspension system to restore auto‑leveling function and stable rear height for better riding comfort.
Core Advantages
Developed for American luxury sedan, ozone‑proof, aging‑resistant and temperature‑resistant, resist sand and gravel impact, reduce cracking and slow leakage for city and long‑distance driving.
1:1 OEM precision molding, identical wave folds, stroke, base interface and clip position, direct bolt‑on installation without modification.
Every unit undergoes high‑pressure inflation and pressure‑holding air tightness test before delivery to avoid pinhole leakage.
Cost‑effective aftermarket solution. Replace only air bag instead of complete strut to cut repair cost.
Integrated assembly with complete sealing base, no extra gaskets or clamps required for fast workshop installation.
Common Faults Solved
Rear end sinking or vehicle tilting after parking
Air suspension warning prompt and height‑related fault codes on dashboard
Air compressor frequent cycling, continuous running, overheating and increased noise
Uneven rear height, rear sag under loaded condition, poor driving stability
Air bag rubber aging, hardening, cracking, bulging and pinhole slow leakage
Only air bag damaged while original damper core remains oil‑free and intact
Notice: Universal for rear left and right. Full strut replacement is required if damper core leaks or damper assembly gets deformed.
2. Fitment
Vehicle Model: Cadillac XTS
Year Range: 2013‑2019
Fitment: Only for vehicles equipped with factory rear air suspension, including standard, stretched limousine and hearse versions.
Notes:
Not compatible with mechanical coil spring suspension.
Universal fit for rear left and rear right.
Applicable only when original damper core is oil‑free and undamaged. Replace full strut if damper fails.
VIN verification is highly recommended before placing order to avoid wrong item.
Remark: All above part numbers are fully interchangeable in aftermarket. 23116448 is the mainstream reference OE number.
4. FAQ
Q1: Does 23116448 distinguish left and right? Can they be interchanged?
A: No distinction between left and right, fully interchangeable. Same structure for rear left and rear right, fits either side once damaged.
Q2: Does it fit mechanical spring version Cadillac XTS?
A: No. Only fits factory‑installed rear air suspension models. Mechanical suspension lacks corresponding mounting structure and air control system.
Q3: When to replace only air bag vs full strut assembly?
A: Replace only air bag if damper core is oil‑free with normal damping performance and no deformation. Replace full strut assembly if damper leaks, fails or gets deformed.
Q4: Need to replace air compressor together?
A: No. Replace only air bag if compressor works normally without overheating or abnormal noise. Inspect or replace compressor if it suffers heavy‑load overheating and performance degradation to extend suspension service life.
Q5: Is calibration required after installation?
A: Yes. Professional diagnostic tool is required for body height calibration and suspension reset. Without calibration, height deviation and fault alerts will occur.
Q6: What is the warranty coverage?
A: 12‑month standard warranty covers natural aging, cracking and slow air leakage under normal operation. Damage caused by collision, chassis scratch, improper installation, modification or water immersion is excluded.
Q7: How to confirm compatibility?
A: 1. Check factory configuration via 17‑digit VIN; 2. Verify OE number printed on old air bag; 3. Confirm original damper core is oil‑free and undamaged.
Packaging Customization: EPE foam protection, color box, export carton, custom shipping mark for sea / air freight, suitable for LCL, FCL and overseas‑warehouse stocking.
