Ask a question to 1A Auto customers who purchased the product
is this a replacement for the factory original self leveler air shocks?
Alex M August 22, 2017
This will be a conversion kit for the self leveling air shocks.
Alex P August 25, 2017
Is this kit comparable to part # 19300025?
Jeannette G June 19, 2018
In order to determine if a kit will fit your vehicle, you should match it up according to your year, make and model, and other trim specifications if listed below the listing.
Peter M June 19, 2018
Well yes these parts are two different parts. The conversion kit basically removes the air ride. It’s and spring instead of air not knowing if my air Compressor was working properly this is what led me to go with the conversion which was easy Like for like just took the air hose crimped it in zip tied it . The part # 19300025 the one you provide uses the air. Which would be ready plug and play but if you use the air and want to air not sure on that i didn’t want to bother with pumps and lines and relays to run them . Hope this helps.

What do you do with the air system to stop the compressor from running?
Bill G June 21, 2018
Easiest thing to do is look on your owners manual for the fuse box. Look for the fuse that say compressor or ait ride. Try removing the fuse I am sure it will probably be like maybe 20 or 30 amp I am guessing. Pull that fuse it should shut it off it is what I plan to do when I get done. Let me know how it goes for you.

Hello, You can pull the fuse out but it may turn a light on your dash.

Unplug the compressor under the passenger side of the car towards the rear end.
T O June 22, 2018

M E June 25, 2018
