Replacement front springs for 1986 Colony Park

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.
