Crown victoria Grand marquis Town car 3" Rear lift

Installing these lift a brand 3" lift cups in the rear of my grand marquis.
I had already purchased and installed them but there was more squeaking in the rear than I was comfortable with. I also took out the axle and had it rebuilt using a P71 Limited Slip Differential, 373 gears, and, police axles. I like that it's lifted and retains the factory smooth ride, and with the air lift 1000 bags, I can adjust stiffness, a little bit of ride height, and pump some more air in them if I decide to tow something. As a safety concern, I decided to weld the cups to the axle, so they didn't fall out while air borne. I also added a 1" tall piece of 2"od 1.75"id pipe to keep the springs in place on top of the spacer. I highly recommend running the rubber grommet/bushing.
Hope this helps someone.

Very informative thank you, brought cup lift kit, will get 1" pipe from shop to weld sleeve.

I put them on the top of my coils on my ‘95 mgm because it fit tighter, and it stays with the body. I didn’t want it taking all the movement and impact that the axle has on bumpy roads. Haven’t had any issues yet and I’ve been airborne and on very rough trails going fast.

Could you do a video on the fronts? I have an 01 crown Vic police interceptor I’m currently doing

[@TACOMASRT5]

The 01's are a different suspension design up front and I just don't have one to work on, sorry man.

Plz any body watching this video plz don’t be stupid an weld or tac weld shit you’ll have a major issue when time to take it off when you don’t want it on which will cause holes in your axel when you tap the cups off with a hammer once they get put on a springs sits on top of them an yoy mount everything back up an get your shocks bolted back up all that pressure will hold those cups tight in place never weld anything on your axels

[@TACOMASRT5]

Excellent advice as a disclaimer. However every axle has something welded to it in order for it to be bolted on. Personally this Was an off road project and I had planned on being airborne and didn't want them falling out and I had heard of them falling out on pavement princesses over speed bumps so I just wanted to be sure.

@@TACOMASRT5 should’ve just put longer spring I’ve lifted cars 20 years yes they welded shit from factory because they no what there doing but tac welding a cup to the axel of a car for a dumb reason is not really smart on your part js saying add longer springs or buy a truck js my opinion

[@TACOMASRT5]

@@simsatvrepair1255 I agree. A much better option given you could find the correct springs for your specific needs

[@simsatvrepair1255]

@@TACOMASRT5 I’m js if you your going to run a CAR OFF-ROAD you should use longer springs or a stiffer spring with lift cups so they don’t fall out an tbh lift cups want fall out if put in right an stiffed js

@@simsatvrepair1255 Settle down bud it's a 2000 dollar car I guarantee when they get scraped it's not because of some tiny welds on the outside of the axle

[@seanschubert8696]

What is the thing called that squeezed the spring together and what brand?

[@TACOMASRT5]

Coil spring compressor? That is a tool that helps in spring installation. Coil spring spacers are what I installed on the axle to lift the car

[@alonzowedlaw4578]

Can you use square tubing instead of piece of pipe

[@TACOMASRT5]

I mean I guess you could, but I think it old be more time consuming and expensive to build your own. Their cheap on ebay and Amazon

How did u lift the rear i got a 03 lincoln im tryin to lift but i still have may air ride suspension in rear

[@TACOMASRT5]

I'm not sure if the bags will work with this or not, but probably not though. If you go with these you will need to switch to coil springs. Some people switch to springs out of an explorer or excursion I think? But that would be too stiff a ride in my opinion.

[@DeeMoneyG]

@@TACOMASRT5 sorry for the late reply i have coil springs now got rid of the air bags the rear is lower then the front would u use cups

[@DeeMoneyG]

Are u in tacoma Washington

@@DeeMoneyG no lol when I started my KZbin channel my Toyota Tacoma sr5 was modified so I used to make a joke with people that it was SRT5 In sttead of srt4,srt8, or srt10 like a dodge

[@TACOMASRT5]

@@DeeMoneyG you got rid of the factory air suspension? What springs did you get? There are several cups available I would make sure whatever size you get is made of steel so you can get them welded to the axle so they don't fall out
