Review on Optimized Coil Spring Set - Moog CC865 by Damon Fields

I bought these springs for a 2008 Mercury Grand Marquis. My car started to sag in the rear and I wanted to go back to stock ride height. MOOG has always been a respected brand in my opinion and I thought they were better than any other options on the market. I received them very promptly and started replacing them. They came with four isolators and my car only needed two on the springs. After some research I found that the closer coils are on top, which was not stated in the instructions that came with the product. The manual only contains information on disabling the air suspension system in vehicles originally equipped with it. After installing the springs, I bolted the rear shocks back on and lowered the car. The springs definitely gave the car the rear height I was looking for and I'm very happy with that aspect. The spring feels a bit stiffer than the factory springs, but overall it rides well. I would recommend these springs if you are looking to replace your old ones.
