VERY PLEASED
I CHOOSE YOUR IN -HOUSE BRAND OVER THE BIG NAME BRAND AT A CHEAPER PRICE AND WAS VERY PLEASED WITH THE TOUGHNESS/STURDY FEEL TO THE SPRINGS. THREE OF THE COILS INSTALLED QUICK AND EASY AND THE FOURTH ONE WAS OFF BY A HAIR AND TESTED MY PATIENCE BUT WAS ABLE TO GET IT INSTALLED. TRUCK RIDES GOOD NO PROBLEMS

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.

In the description parts list an item described as conversion kit is listed. What is the conversion kit?
Joe B 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.

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
