Air Spring Assembly OE 2918020-H19C2 for Dongfeng GX & KX Heavy Trucks

This genuine air spring assembly with OE number 2918020-H19C2 is factory original cab suspension component exclusively matched for Dongfeng GX and KX heavy-duty tractors. It serves as elastic support between truck cab and chassis, relying on compressed air inside rubber bellow to buffer vibration transmitted from rough road surfaces. The air bellow adopts multi-layer composite reinforced rubber with high tensile strength, resisting aging, ozone erosion and repeated stretching deformation. Upper and lower metal end caps use anti-rust surface treatment, equipped with standard air nozzle interface matching original cab air pipeline. Constant air pressure damping effectively isolates vibration, easing driver fatigue and avoiding cab structural fatigue damage. This air spring strictly passes DFCV OEM cyclic stretching fatigue test, air tightness durability test and high-low temperature aging test. Authorized third-party suspension component inspection verifies mounting size, air connector specification and rubber performance fully consistent with factory original assemblies, widely used as replacement spare parts for air leakage, cracking and failed damping air springs on Dongfeng GX & KX long-haul fleets.

PRODUCT DESCRIPTION

Multi-Layer Reinforced Rubber Bellow, Anti-Aging, Stable Air Tightness, OEM Matching Mount Structure

This OE 2918020-H19C2 air spring adopts multi-layer cord reinforced rubber air bag structure. High-quality rubber formula delivers outstanding resistance against ozone, ultraviolet and temperature change, effectively delaying aging cracking. Integrated sealed metal end caps undergo precision machining, and the whole assembly maintains stable air tightness under long-term cyclic compression and stretching. Standard air inlet nozzle completely matches Dongfeng GX & KX cab air suspension pipeline, no extra adapter needed during installation. The reserved mounting hole layout is 1:1 consistent with cab bracket, realizing direct snap-on assembly. Internal structural design ensures linear elastic damping, efficiently filtering bump vibration from uneven pavement, greatly improving long-distance driving comfort for truck drivers.

Thin Rubber Easy Crack, Poor Sealing Cause Air Leakage, Mismatched Size Unable To Install

Heavy truck cab maintenance technicians often encounter suspension failures caused by inferior aftermarket air springs: thin single-layer rubber air bags crack easily after repeated vibration; rough sealing between rubber and metal end caps leads to slow air leakage, resulting in stiff cab suspension; non-standard mounting size cannot align with Dongfeng GX/KX cab brackets, requiring cutting and modification. This genuine DFCV OEM air spring eliminates all these hidden troubles: thick multi-layer reinforced rubber extends service life; integrated sealing prevents air loss; original size fits perfectly without refitting, lowering cab suspension maintenance frequency for Dongfeng GX & KX logistics fleets.

DFCV OEM GX/KX Cab Suspension Standard, Multi-Round Fatigue, Air-Tight & Aging Lab Testing

As core damping spare part of Dongfeng GX & KX heavy truck cab air suspension system, this air spring fully complies with Dongfeng Commercial Vehicle official heavy-duty vehicle suspension component production standards. Every finished air spring completes three mandatory durability laboratory tests: millions of times reciprocating stretch fatigue test, long-cycle air tightness holding test, -40℃~+85℃ high-low temperature aging test, maintaining stable damping performance in northern cold regions, high-temperature plateau and coastal humid environments. Anti-counterfeit QR code and OEM part number are marked on original packaging for authenticity verification. All mounting dimension, air nozzle position and rubber bellow specification strictly follow factory engineering drawings, zero assembly mismatch for all Dongfeng GX and KX heavy truck models.

In-Stock Genuine OEM Air Springs & Fast Low-Downtime Cab Suspension Repair Wholesale Supply
