Working great on my 2000 Grand Marquis. No more suspension faults and the ride did improve overall. If you follow the instructions concerning the suspension fault lamp you should not have any lights on dash.I was only able to use top rubber pads on the springs. ( factory springs have none at the bottom). Very happy so far. Would recommend to others.

Direct replacement for failed air springs, even came with isolators.They ride nice too, but not as smooth as the air bags. However, after 4 months, the car does sit pretty low in the back. Planning on cutting a coil off the fronts, OR putting some 'helper' bags inside the rear springs.

This fit my 2008 Mercury Grand Marquis. The compatibility probably doesn't list this year due to the original air suspension, so it's not a direct replacement.My car came with a ford constant rate coil spring which was great - comfortable, not floaty. However after sitting on the incline on my driveway, it started to compress and the muffler started to scrape the driveway every time I parked.I switched to a Moog CC865, which is a much stiffer spring, and probably useful for heavy cargo applications, but it was just too painful to live with.Finally I switched to this AC Delco which I research and found the spring rate to be around the same as the original Ford at around 100 LBSInch, unlike the 163 listed for Moog. It beats me why this information is not listed everywhere in the item's specs, I had to search for 30 minutes to find this info.This spring is still a bit stiffer than Ford's, probably due to it being a variable rate coil spring, but it's comfortable enough and a good compromise between maintaining ride height and comfort.

These springs come with insulators.Installation was easy...Jacked up the car until the rear tire started to come off the ground..released the shock jacked up the car another 4" and removed the old spring by reaching above the tire. Went under the car and put the new spring in with the insulator taped to the spring with electrical tape..I had previously placed the bottom insulator..it took more time to get my tools it than it did to replace the springs...in all it took maybe 20 minutes.

I have three towncars. About 2-3 years ago I replaced leaking air bags on '98 TC Sig with Moog CC865 springs. I don't recall the details but job must've went well enough and I'm still pleased with results.Earlier this month, I replaced leaking bags on a '99 TC Sig with ACD 45H1137 springs. In addition to leaking bags, the air compressor pump actually "threw a rod" no joke. It's got a 4.6 L V8 for power but there's 9 connecting rods underhood. I think these ACD springs and insulators and instructions are identical to Moog CC865. I clearly recall this job went OK. However, instuctions speak to making sure axle is supported before disconnecting shocks so it won't drop too far. I had much trouble getting axle to drop far enough to pry springs in. I ended up loosening the brake hose clamps (not hoses themselves) on each side and the small position sensor switch-spring at center axle. Then I used car's supplied scissor jack; insterted just above axle and just below frame loop ... extending jack an inch or so forced axle to lower and permitted me to insert spring; repeated process on other side of car. I am pleased with the result. These ACD springs seem same as Moog equivalent but sell for a bit less.Also, I ordered these ACD springs via standard free amazon ground shipping. I placed order about 2:30PM on a Wednesday. Package arrived VERY NEXT MORNING by 10 AM. I had springs in the car and all cleaned up by same afternoon. I reside rural South Carolina but I cannot be sure where springs shipped from; seems either Kentucky or Virginia.Oh, in each case I did the work solo with car jacked up on grass in yard.with good hydraulic jack and jackstands w/ floorplates..And I ain't no spring chicken

Three basic comments on these springs:First, for those wondering, even though they're not listed, the two coils come with four rubber insulators. Since I was replacing my rear suspension air bags on my 1998 Lincoln Town Car, I only needed one insulator at the top of each coil. The bottom does not need one.Second, I expected a bit more trouble actually pressing them into place than I actually had. Since I was also replacing both shocks, I simply removed them first. If you're not replacing the shocks, you can just remove the two lower shock mounting bolts to loosen the axle. I held the upper rubber insulator in place using electrical tape, then lined up the top of the spring with the upper mounting location. Then I used a small pry-bar to ease the bottom of each coil up, over, and onto the bottom mount location. Took about 1 or two minutes per coil to install.Finally, on my 1998 Town Car, there's much conflicting information on removing the AIR SUSPENSION dash message. I have a feeling some people are right that the only way would be to reprogram the computer. The 1998 is different than previous models. Cutting a wire doesn't help. I DID leave the solenoids on the end of the cable and when I turn the suspension switch back on, the dash suspension indicator does turn off and the air compressor does not try to pump up the now missing bags. However, after driving high speed and then slowing down, I have had the message come on. Guess worst case I can cover it with more electrical tape.I figured I'd share my experience to possibly save someone else some time. I'm very pleased with the coils. I did not choose the MOOG coils because it looked visually like they might have a tighter/stiffer ride than these.
