Works Well
I am happy with this compressor much cheaper then the gym part fit awesome, everything is plug and play from electrical to air fittings. Only issue I had was the driver side air fitting that connects to the shock was super tight to get is seated to the keeper pin. Eventually got in on with some persuading. But other then that install was about 20 min awesome product!!

Dorman Compressor
They send you the product looking like a new one even though it is remanufactured with all the plugs and sealing. Easy to install and working like a new one with a good pressure. Oh yeah so I don't forget the life time warranty.

Dorman Air Compressor
The product came expertly wrapped and looked absolutely new. It is a complete breeze to install and even included replacement nuts. The Dorman Air Compressor when installed ran as quiet as when the car was brand new. The performance is perfect.

This pump description stayed that it fits my vehicle. It does not. I was stuck without a vehicle so I modified it. The mounting bracket that is tack welded to the motor housing was in the wrong position and it was not tall enough. I cut the bracket off of the new and old motor and welded the old bracket on the new motor. I felt misled.
