Performance Handling. These Eibach Pro-Kit Progressive Rate Springs will lower your Mustang's center of gravity, reducing body roll in the turns, squat during acceleration, and excessive nose-dive under hard braking. A set of Eibach Springs are great for daily driving, street, and even track use.

Classic Muscular Stance. Not only does a set of Eibach Pro Kit Springs improve the handling performance of your Mustang, but they also improve it's overall appearance by lowering the ride height to eliminate the huge tire to fender gap, for a classic muscular stance.

  • Lowers 1994-2004 V6 Coupes: Front - 1.5”, Rear - 1.5”

Progressive Design. Eibach's proprietary progressive spring design provides the ultimate balance to deliver aggressive good looks and high performance handling, without ever compromising safety or ride quality.

Recommended Upgrade. When installing new springs you should also replace your old worn out rubber Spring Isolators with a new set of Polyurethane Spring Isolators, see drop down option above.

Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your factory size wheels and tires, as well as AmericanMuscle’s pre-configured wheel and tire combo kits (specific to your generation), to assure proper clearance with no rubbing issues.

Application. This set of four Eibach Pro Springs are specifically designed for use on the 1979-2004 4 cylinder and V6 coupe Mustangs. The springs are not compatible with SVO and Convertibles models.

Is it a big deal if i do not buy the front and rear isolaters I have a 03 v6 mustang with 110,000 miles on it with all stock suspension parts. Is it a big deal if I do not buy the front and rear isolators with the lowering springs? will it effect the ride quality or even effect anything at all?


  • You should definitely replace your front and rear spring isolators when installing a set of new lowering springs. They are more durable than the old, wore out stock isolators and will greatly improve your handling and steering response. They will also prevent any unwanted metal on metal grinding, keeping your ride smooth and and quiet. Hope this helps!

Question Resolved

Do you need a Isolator for each spring 2 for the rear and 2 for the front. Thanks Brian


  • Yes, you should install new isolators for each spring. The front has a two piece for each spring # part 56054. The rear # part 56055 . These items are from AM and are on the web and catalogue for about $29.99 for each set.

    These springs were easy to install. Greatly increased the look of the car, the 4X4 look is gone. The car rides high enough to still stay over concrete parking stops too. Even with the mach 1 chin spoiler on. The only problem with this kit was that i had to purchase camber bolt to align it to spec. Overall a great kit for looks and handling. But not extreme that it requires suspension to be changed out.

    I ordered these on Monday, got them in on Friday, and installed them myself on Saturday. It took about 2 1/2 hours to install. I didnt have a spring compressor and it was fine, but you have to have a low profile jack and jack stands to do this job correctly. And the way my car sits now is amazing. It looks like a car that looks fast when its just parked. I have a 2000 V6 Mustang and it lowered it exactly 1.5 inches. I HIGHLY recommend that you buy the spring isolators with them, because when I pulled my old ones off they were ripped and torn really bad. A MUST BUY if you want style and handling.

    I installed the Eibach Pro Kit springs and Eibach Pro Damper shocks, and the handling is markedly improved. My car has 114k miles on the original suspension, so I actually feel that the ride hasn't suffered from the upgrade. I would recommend getting the caster-camber plates if you're going to drop the ride height. I had installed the Eibach stabilizer bars this summer, and the combination of the three really sharpens up the ride, and dropped the ride 1.5" as advertised. I would recommend getting new spring isolators, because mine were shot. I installed this with two friends and we were able to do it ourselves, but it would be hard solo if it's your first time working on a car.

    Great springs - 96 mustang V6

    Easy Install, looks great, performs great, drives like its on rails ^_^ If your looking for your mustang to ride like a cadillac then this isnt your setup, stiff springs = stiff/rough ride, but i love them ^_^

    2002 V6

    These springs ended up being exactly what i wanted. I didn't know how low i wanted my car but the 1.5" drop all the way around is perfect, not to low that you bottom out on everything, but low enough to improve on the handling and get rid of the ugly tire fender gap and line up with the wheels. Huge difference than stock springs, it feels like you are driving on rails and you can really feel the curves, just how I like it. Had my shop put them on, and the isolators were in great condition so new ones were not needed (80k miles). Thanks again American Muscle!

    Great Springs

    Recently installed these and have to say they can't be beat. Looks good and performs better around the corners. The only thing wrong with it is there are no instructions so if you don't know your way around the suspension then the front could be a little hard. I had to pretty much unbolt anything that would keep the a-arms up including the brake line to even get the old springs out. Also my car has just under 60k miles on it and my spring Isolators were in great condition front and back. Thanks AM

    Eibach springs w/lower ball joints And American muscle rims/tires

    I've changed the original stock 15 inch wheels And rims at the time of spring install . I went with the 17 staggered look with nitto555 . And installed lower ball joints since i was going to have it apart . This car is totally different now ! The ride is amazing !

    Just installed these over the weekend and love the ride, definitely better than stock. I would recommend having a shop install them. Without a lift and spring compressor it would be difficult.
