04877136AB 04877136AA Rear Air Spring Bag For Dodge Ram 1500 2009-2018

04877136AB and 04877136AA are original iterative universal core air suspension accessory models of Dodge, suitable for 2013–2020 Dodge Ram 1500 all original air suspension versions. As a high-frequency vulnerable part of American pickup rear air suspension system, it is widely used in 4S shop original maintenance, used car renovation, professional repair shop precision maintenance and cross-border auto parts foreign trade batch replacement.

Dodge Ram 1500 focuses on heavy-load performance and is equipped with original adaptive rear air suspension. The rear trunk bears large load and high working pressure. The original rear air spring is easily affected by long-term high-pressure load, frequent road bumps, outdoor high-temperature sun exposure and winter low-temperature frost erosion, resulting inrubber hardening & aging, bladder cracking, delamination & bulging, sealing port pressure relief and chronic air leakage. Common faults include overall rear body sinking, air leakage and collapse after overnight parking, body skew after loading, rear floating at high speed, chassis abnormal noise and air suspension fault light on.

When the original rear air spring has structural damage such as bladder damage, deformation and continuous air leakage that cannot be repaired by repair kits, direct assembly replacement is the most cost-effective and reliable maintenance solution. Manufactured in strict accordance with original factory technology, pressure parameters, bladder stroke and mounting points, this product is fully compatible with the original vehicle air suspension control system, supporting non-destructive in-situ direct installation without pipeline modification or bracket refitting. After installation, only air tightness test, rear body height calibration and fault code clearing are required to completely restore the original rear air suspension supporting performance and driving texture.

Important Notice: This product is an exclusive rear air spring for Dodge Ram 1500, universal for rear left and right, non-universal for front and rear; only applicable to original air suspension equipped models, not available for mechanical spring suspension vehicles.
