Full Coilover Kit for MM

[Chard]

I'm planning on doing a full restore/improvement on the factory suspension on my MM. The idea is to go full coilover kit as i have done with my previous vehicles. Currently from what i read is most people go for the HQ Ridetech kit with the NAAKE/QA1 being a hit or miss.

This is where i get a bit confused, it seems Both kits only offer a front kit or am i not searching correctly.

Does any one have a full Front/Rear Coilover kit for the MM?

For a reference i have a 300A MM

Have you taken a look at your rear shock, or its placement?

Yes, what about it ??

[RubberCtyRauder]

just use your air ride height adj. there ae no coilovers for the rear. it would need fabbed up to hold.

[Chard]

I should of mentioned this in the original post, My MM is equipped with rear coils. not airbags

[RubberCtyRauder]

the present rear mounts are not rated, nor room for coilovers. custom job to make work

Please share pictures and details. You relocated control arm, moved shock, etc.

I didn’t modify anything in the rear suspension. I bought the car like this. My idea was since it was a 300a it was a pre air suspension car.. but now I’m starting to think i may have been wrong this whole time

[RubberCtyRauder]

marauders were all rear air spring cars..someone switched them out to springs. rear coilovers ae not a bolt on option, will require fabrication

While you're throwing money all over the place, maybe get someone to develop a un-poverty coil rear spring set up.

The op's car had the air suspension swapped out with coil springs. Doing such is commonly referred to as "poverty coils".

My idea was since it was a 300a it was a pre air suspension car..No such thing. All Marauders have RAS unless converted by a previous owner.

[Chard]

Well, this is what i get for not doing a better research on these vehicles.. So i found the switch, the compressor and what seems to be the lines are still there. Well since now i know i can only get the front Coilover kit, ill be removing the rear coils and replacing them with the appropriate airbags and using the ride height adjuster to lower the rear end. With that in mind what brands do you guys recommend?

[NorthShoreChiMM]

Get the suncore ones. Prob the best aftermarket bags out there

[RF Overlord]

Not to create a war, but the Arnott Limo bags are also very good.

[jaywish]

OEM air springs seem to still be available from a quick online look.

A quick word about rear springs: if you're going to convert, just get springs from '07-'14 Mustangs. I use '11-'14 GT springs and couldn't be happier. They cost me $20, were basically brand new, and had a 3/4" drop over my stock Grand Marquis springs. Any air bag replacement springs will also sit way too high.

Now for a rear coilover setup: it is actually possible and has been done, HOWEVER, the guy who did it, his Crown Vic is a road race only car. He uses a coilover rear shock in place of the stock rear shock with a modified upper mount and no springs sitting between the axle & frame.

[Lowndex]

Imagine a Marauder with a fully independent rear-end with coilovers.

There's a guy on CVN that has done this, too - for the O/P, Google "MEDC suspension info"...

That's who I'm talking about, his name is Sean. Very knowledgeable guy. He taught me everything I know about using rod ends to make suspension components.

The vehicle has already been converted to Coils by the previous owner. I'm assuming you did the same conversion yourself? Did you have to any modifications to rear axle housing to install the mustang springs.. because if possible i would like to get some GT500 Springs as they have a stiffer spring rate.

Sorry before hand to revive an old thread -
I was also curious about a spring conversion in the rear end awhile back.

If you are converting to coil springs know that the lower spring perch or mount was different than a CV. If I recall correctly that perch on the air bag equipped cars won't allow for an adjustable spring perch to sit correctly. If that's the case a coil spring equipped rearend housing or the brackets from a coil spring equipped car will be required or have to be fabricated and welded onto your existing rearend housing.

So much fail in these pictures. Just because the shock bracket hold the weight of the car doesn't mean it should. Look at the stress cracks in the paint from flexing. This is destined for disaster.

The front sway bar end links are also full of fail. there is no advantage to using those over the stock ones.

The front coilover spring is located at the bottom. It should be at the top away from the moving suspension components. It must hit at full extension. there is a reason every strut has the sprind at the top including similar setups like Naake and Ridetech.

WHEN I IMAGIN IT... I SEE IT ON YOUR CAR!

Yes I've been told i would need to swap over a CV rear end or remove the bracket and get it welded into my existing rear end. Currently i'm leaning more towards just removing the Coil springs and returning the vehicle back to bags. But without the information on as to why the swap to coils was done. I'm a little uncertain if i want to tackle that when i have alot more things to fix. So unless i come across a complete CV Rear-end with LSD and a decent ratio. the Rear end/suspension is going to have to wait.

A 2007+ Crown Vic axle housing is identical to a with these exceptions:

- The Marauder has taller bump stops.

- The vent tube is different

- The differential cover is steel and has a plastic bumper on it.

Other than those items, they are the same the spring perches are the same.

if it aint broke, dont fix it - as for why it was done in the first place, anyone's guess

The reason I don’t use factory endlinks is that at my lowered ride height, they would bind, and constantly break.. ford, moog.. did the rod ends.. as for the front coilover inverted.. I did that so the adjusters are up top, shock company has confirmed the shock can be ran inverted.

The rear shock mount has been braced as well.. hard to see in photo on a phone.. I think Tapatalk scales the photos down?

The shock mount was fully welded, and then braced in the rear.. then sprayed with whatever paint I had on hand..

I’m the MEDC guy.. [emoji112]
