Robert Kyle Posted October 12, 2014 Report Posted October 12, 2014 I'm looking to get the rear end of my 2004 Mercury Grand Marquis? Does anyone have a solution for this? I don't want to use the blocks that go under the springs because I take the subs out sometimes. Any help will greatly be appreciated.
Broke_Audio_Addict Posted October 12, 2014 Report Posted October 12, 2014 How much weight do you have back there? If it's not a lot track down a p71 suspension its much stiffer than your stock suspension should help with the sag. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
Robert Kyle Posted October 20, 2014 Author Report Posted October 20, 2014 I have two AQ Hdc3 15's with custom built box, one xs d3100, soundstream ta1.3000d, Rockford p400x4 back there and it sags pretty bad. I tried those spring boosters and they keep breaking or falling out.
Marquisboys Posted October 20, 2014 Report Posted October 20, 2014 my last car was a 04 grand marquis. had the same issue. I put kyb heavy shocks in and on rockauto.com they have police spec springs for the front and rear. I put all those shocks and springs on the car and it didnt even budge with the extra weight in the trunk. It handled alot better and gave it a firmer planted ride (which some may not like) Also there is Airlift 1000. Its about 80 bucks for the kit and its air bags that go inside your springs. So than you can make the bags however hard or soft you want 2004 Grand MarquisAA Mayhem 18Crescendo 3500d6.5's AQ Pro AudioAQ Super TweetsImage Dynamics 6x9Soundqubed 125.4MB Quart 80.4144.2 db GONZO 2013 Chrysler 300S Granite Crystal Metallic Exterior Inferno Red Interior 5.7 HEMI AWD LMI Air Hammer Intake Corsa exhaust Custom Tune
Robert Kyle Posted October 21, 2014 Author Report Posted October 21, 2014 Thanks @marquisboys. I might try the air lift kit.
