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.

She's sittin' up now !
Got the kit... cheapest and fastest delivery. Better quality than expected, at least as good as the more $$ ones ( I've 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+

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????
