Poor product
Kit was incomplete. Advertised as meeting other manufacturers kits and everything needed to make my car work as needed- not true. Salesman unable to solve missing required part problem. Was not impressed with product quality. Just watch what your buying. Problem resolution dept- slow. Situation was resolved by manager. Thank you. But slow in timing. Car was down and i was left to find the missing shock mounts on my own. Money refunded took week????

Shes sittin up now !
Got the kit... cheapest and fastest delivery. Better quality than expected, at least as good as the more $$ ones ( Ive done the conversion on a few Lincolns) Powder coated springs, decent gas shocks with hardware and OK instructions. Delivered ON TIME. My Townie is now sitting up in the back, maybe 2" above Air Ride. Smooth ride, about the same a Bag. Like they say "No Air, No Care" A+

Saved money, rides great now
This kit is great, I had to get it cause the air springs frequently failed. Great decision, I saved a bunch of money. Only difficult part was getting spring on because I didnt have the spring compressor. Now it rides smoother then it did with the air springs, very happy with this purchase.

Air ride to coil spring conversion - the ride is the same
I have a 2002 Lincoln Towncar with 223,000 miles on it. The air ride suspension went out recently when the air bags developed a leak. This is a fairly common issue with air ride suspension after the number of miles Ive put on the car. When the air bags went out, I considered replacing them but opted instead for the coil spring conversion kit because the price is so reasonable. However, I was afraid the ride would suffer as Ive become spoiled by the air ride of the Lincoln Towncar and thought that the coil springs would be much stiffer. To my surprise, there was little difference after I did the conversion. Furthermore, it was a simple conversion to do. Im 67 years old and dont really like getting under the car to do this kind of work but this job was easy enough that I was able to do it myself in only a few hours. Great product!

Great product for the price
Excellent product for much less than other retailers. I was very pleased with this conversion package. It literally had everything I needed to convert my 2000 Lincoln Town Car rear end from the broken and leaking air bag system to an amazing normal looking and riding car. The rear end of my car now looks like its supposed to. Thank you Jesus

Easy install
Nice way to delete the rear air ride in my Lincoln. Required spring compressors to get into place, but installed in a few hours by watching some YouTube videos first.

Do could anyone tell me what special tools would be needed for installment? 1999 mercury marquis. Thank you
Billy G November 2, 2019
Nothing special just regular tools. I didn’t buy any special tools. Jack jack stand, sockets to fit and open ended wrenches. It is time consuming just take your tine.
