Review: Great set to convert your failing air suspension!!! - Worked a charm!!! Reasonably easy to install! If your old air suspension is failing in your lincoln, mercury, or ford that this set will fit then its a no brainer!! Order this and fix your cars draggin rear end for a FRACTION of the cost of fixing the air suspension itself or buying the parts anywhere else to do this conversion! My 01 lincoln town car is like new again.. maybe better!
Review: Perfect air ride conversion for Town Car - Used this kit to convert my 97 Lincoln Town Car from the original air springs. Worked perfectly, very easy to install if you follow a youtube video. Rides perfect and stance looks the same as it would with air ride. Only down side to this kit is it only comes with 1 nut for the top of each shock. With the way Ford manufactured the frames for these cars it's pretty damn tough to get the top nut on the shock without losing it in the frame due to tiny hand space so I'd recommend getting a few extra from a hardware store before trying to install them.

## Questions & Answers

**Q: Those are coil springs?**
A: Yes. I put a set in the rear of my 01 Grand Marquis as well as shocks all around.

**Q: Is there a manufacturers warranty???**
A: I believe there is. They do work very well, though. AllI have left is the rear sway and she'll ride allot better.

### ⭐⭐⭐⭐ Great for the price
*by B***N on February 25, 2022*

They fit perfect on my 01 Grand Marquis. It feels so much better than before. It would have gotten 5 stars but I thought they should have been slightly stiffer in the front. It is a major improvement than the annoying bags.
