Conversion shocks
They work great but the boxes didn't hold up very well. The instructions don't tell you how to disable the air suspension warning light that comes on once you have replace the factory shocks, but other than that I will be purchasing other items from them ,also will refer friends to the site. The prices were great too.

I have a 04 lincoln aviator would this part fits my vehicle?
Norma S on Dec 1, 2016
BEST ANSWER: no, this fits the full size navigator.
In the description parts list an item described as conversion kit is listed. What is the conversion kit?
Joe B on Feb 19, 2016
BEST ANSWER: Depending on the oem there could be provisions for terminating sensors. I replaced factory air suspension in a Lincoln Navigator, the installation was simple. On some vehicles there could exist a need to tell the vehicle that the suspension is functioning normally to avoid driver display warning lights. The instructions are clear for each vehicle and the manufacturer should be able to assist you with any technical issues. Make certain to have a 4 wheel alignment done as soon after install as possible.
Will this kit make the ride higher, or can you adjust the height sensors?
nsshh on Jun 16, 2017
BEST ANSWER: It did make my truck higher but only because before it had air suspension. After a while it went back to normal. I did not try to adjust height sensors so I don't know.
