In the description parts list an item described as conversion kit is listed. What is the conversion kit?
JLB J February 19, 2016
Converts the factory AIR RIDE to a COIL SPRING kit. Eliminates air, compressor, bags and so on.
Brian F February 23, 2016
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.
Michael L February 25, 2016
I have a 04 lincoln aviator would this part fits my vehicle?
Norma S December 1, 2016
No
Brian F December 1, 2016
no, this fits the full size navigator.
Gary P December 2, 2016
Will this kit make the ride higher, or can you adjust the height sensors?
Natasha H June 16, 2017
These will set the ride height to factory specs, and cannot be adjusted.
Tim K June 18, 2017
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 dont know.
Kevin V June 18, 2017
Yes it will be higher than the air ride. About 2 or 3" higher
Lee S June 18, 2017
It actually kept it at the factory height. I dont think you can adjust for different heights.
Manuel L June 19, 2017
It maintains factory height. No adjustments.

Conversion shocks
They work great but the boxes didnt hold up very well. The instructions dont 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.

Solved the Air Ride Suspension Problem
After spending over $2,000 on replacement parts and labor to "FIX" the air suspension problems … we finally turned to this set of springs & shock replacements. They fit perfectly, solved the problem at once! It does not ride quite as softly as the Lincoln air ride. But the most important things is that it is fixed! Only been installed about two weeks … but so far, it is good. Do this first replacement set of springs n shocks FIRST! Dont waste time and money trying to fix air system.
