    Hi, does anyone happen to have the front OEM coil spring specifications for a 1986 mercury colony park? If so, that would be much appreciated. Thanks

    I could not find listed specs for your wagon, however I did find many different sites including Ebay, Amazon, RockAuto, and ShockWarehouse which sell a MOOG 8795. These websites indicate that the part is a direct replacement for an `86 Mercury Grand Marquis Colony Park 4-Door Wagon.

    Then searching on MOOG's website I dug up the following information:

    ID - 5 Inches
    ID - 127mm
    Bar Diameter 0.62 Inches
    Bar Diameter 15.90mm
    Spring Rate - 182 lbs per inch
    Load 790 lbs
    Installation Height - 12.69 Inches
    Installation Height 322.30mm
    Free Height 17.04 Inches
    432.80mm
    Pigtail ends on both with a constant rate spring type.
    Design load - 1100 ??lbs??
    No bushings included.
    8.16 coils with an outer diameter of 6.260 inches.

    I appreciate the help, but i need the OEM specs. I replaced the rear springs with MOOG springs with what I thought were OEM height, but actually ended up being a couple inches shorter and so now my wagon is squatting. I don’t mind the look so I’m going to try and lower the front as well the same amount as I lowered the back, so I need to know what the front spring OEM free height is. Thanks

    I don't think there is a free spring height specification, but there is a body ride height specification. You can Google it, see if it's on the Net.

    You could always just cut a coil off each front spring to lower it where you want it.

    How about some airbags? I think it was a factory option

    On the rear, and IIRC, the sensor did have three adjustment notches. The only Blue Oval car I know of with four-corner airbags was the FWD Continentals.
