23116448 & 22907781 Rear Air Spring Bag for Cadillac XTS

Main OE Number: 23116448, 22907781

Product Name: Cadillac XTS Rear Air Spring Assembly (Universal Rear Suspension Air Bag)

Installation Position: Universal for rear suspension (fully universal for rear left and rear right).Only compatible with Cadillac XTS air suspension models, not universal for front air springs, mechanical suspension versions and other GM series models.

Product Composition: Integrated complete rear air spring assembly, adopting thickened weather-resistant rubber dedicated for North American vehicles, multi-layer high-density reinforced load-bearing cord, original precision sealing port, integrated anti-corrosion metal base and dust-proof protective structure. It is a complete integral assembly with no need to reuse old parts or auxiliary repair kits, supporting direct non-destructive in-situ replacement of damaged original air springs.

• Dual OE precise compatibility for 23116448 / 22907781, exclusive for Cadillac XTS original air suspension configuration, universal for rear left and rear right, custom-fit with zero installation error and no fault code
• Upgraded thickened explosion-proof rubber structure optimized for heavy-load, high-speed and long-distance working conditions of American sedans, high and low temperature resistant, anti-aging, anti-cracking and anti-bulging, thoroughly solves XTS common faults: slow air leakage after parking, rear end sinking, rear body tilting and rear suspension abnormal noise
• 1:1 original factory data reproduction, the air spring inflation stroke, pressure parameters, mounting hole positions, sealing caliber and installation height fully meet GM original standards, no debugging required after in-situ installation, no body deviation and no air suspension system error
• Specially reinforced for American luxury sedan characteristics of large body weight, high chassis load and large seasonal temperature difference, with far better fatigue resistance, tensile resistance and aging resistance than ordinary aftermarket parts, greatly reducing later rework rate
• Professional assembly replacement solution for severe structural faults including air spring surface cracking, bladder bulging deformation, rubber hardening, slow micro-leakage, repeated pressure relief and recurrent leakage after repair kit patching, realizing one-time thorough repair and long-term stability
• 100% high-pressure air tightness test, load fatigue sampling test and weathering aging test for each unit before delivery to eliminate leakage defective products, perfectly restoring original rear body support, vehicle stability and luxury air suspension damping texture

23116448 and 22907781 are original iterative universal numbers of General Motors, serving as exclusive rear air spring assembly for Cadillac XTS. As a core vulnerable part of the vehicle air suspension system, it is a mainstream supporting accessory for market maintenance replacement, vehicle renovation and cross-border wholesale.

As an American luxury sedan, Cadillac XTS features large body weight and high chassis load. The original rear air spring is prone to rubber hardening and cracking, internal cord fatigue and relaxation, sealing port micro-leakage and base sealing failure under long-term heavy pressure, bumpy vibration and alternating cold and hot temperatures. This eventually leads to typical common problems such as rear end sinking after parking, slow air leakage, uneven left-right body height, loose bouncing over bumpy roads, air suspension fault codes and abnormal suspension height locking.

Repair kits cannot completely fix structural damage and continuous air leakage of air springs, so assembly replacement is the most stable and long-term maintenance solution. Manufactured in strict accordance with original factory processes and parameters, this product’s multi-layer explosion-proof composite structure, sealing tension and maximum pressure value fully match the original vehicle air suspension system. It supports non-destructive in-situ installation without chassis cutting, pipeline modification or structural refitting. Air tightness testing, body height calibration and fault code clearing after installation can completely restore the original working performance and driving comfort of the air suspension.
