2 x Rear Air Spring Bags For Mercedes Benz W251 06-13 R350 07-09 R320 06-07 R500

The Following Installation Manual:

1.When the air Suspension being replaced, the matching relay must be

replaced according to the corresponding vehicle. If there is something wrong with the relay which leads the compressor to continuous operation without any break, it will burn out the electric motor or other plastic part.

2.When the air Suspension being installed, the critical parts such as rubber shock pad and damping spring must be fully fixed on the stand without short installation or missing installation (The air compressor is unequipped with parts). With the anti-vibration parts of short installation or missing installation, a loud noisy instance will happen when the air compressor is working for the sake of resonance.

3.Distribution valve,shockabsorber, air tank and tube connector must be checked after air compressor installed to ensure air-tightness. The lifespan of the air compressor will be shortened if the leakage exists.

4.Instruction is not included. Professional installation is recommended Because of the Shock Absorber is sophisticated.
