Original OE Number: A164 320 1025

Product Name: Mercedes-Benz X164 GL350 / GL450 Rear Air Spring, Rear Air Suspension Bag Assembly

Installation Position: Dedicated for rear air suspension system, universal for rear left and rear right, not compatible with front position. Exclusively suitable for Mercedes-Benz X164 chassis GL350/GL450 models with original Airmatic air suspension. Not applicable for mechanical suspension, front air suspension, ML-Class, W166/X166 new chassis models.

Product Description: A1643201025 is an original factory matching rear air spring specially designed for Mercedes-Benz X164 chassis GL350 and GL450 full-size luxury SUVs, serving as a mainstream original iterative universal part. Mercedes GL-Class large SUVs feature heavy curb weight and high rear chassis load. Long-term high-speed cruising, bumpy road conditions and daily load-bearing operation easily cause common original rear air spring faults, including rubber aging, bladder hardening and cracking, layered bulging, chronic micro air leakage, rear sinking after parking, left-right body tilt and unstable rear end at high speed. Adopting European SUV-specific weather-resistant explosion-proof composite rubber, multi-layer high-density tensile cords and integrated sealed dust-proof structure, this complete assembly requires no secondary assembly or old part reuse. It can directly and non-destructively replace damaged, leaking and collapsed original rear air springs, perfectly restoring the original factory air suspension supporting force, driving comfort and automatic body leveling function of X164 GL350/GL450.

Core Advantages

• ✅ 1:1 original A1643201025 parameter replication, with stroke, pressure resistance value, sealing caliber and mounting hole positions completely consistent with original vehicles, supporting non-destructive direct installation, no fault codes and no pipeline or bracket modification
• ✅ Perfectly compatible with Mercedes-Benz original Airmatic intelligent air suspension electronic control system, ensuring accurate body height and stable automatic leveling after installation, fully restoring the original factory chassis driving texture
• ✅ Specially optimized for heavy-load weather resistance of European SUVs, resisting strong sunlight, extreme cold and high-pressure fatigue, eliminating common later faults of old air springs such as cracking, bulging and chronic pressure relief
• ✅ Integrated high-pressure sealing molding technology thoroughly solves classic W164/X164 faults: rear sinking after overnight parking, single-side collapse and body tilt under load
• ✅ Direct assembly replacement solution completely eliminates structural air leakage. Compared with repair kit maintenance, it features longer service life and ultra-low rework rate, ideal for long-term repair solutions
• ✅ Every product undergoes strict factory tests including high-pressure air tightness test, heavy-load pressure resistance test and high & low temperature aging test, delivering stable and consistent quality for 4S maintenance, professional repair shops and cross-border bulk stocking
