Description
Improves Handling. These Ford Racing "B" Springs will lower your Mustang approximately 1" giving it a more aggressive stance and a lower center of gravity greatly improving your pony's handling over the stock factory springs.

Aggressive Stance. Adding a set of lowering springs to your Mustang can greatly improve its appearance by getting rid of that "4x4" look that it came with from the factory for a more aggressive stance.

Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your stock 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. The Ford Racing B Springs fit all Mustangs from 1979 to 2004, except the 1999-2004 Cobra's with Independent Rear Suspension (IRS). Lowers 1979-1993 Mustangs approximately 7/8" front; 1/2" rear. Lowers 1994-2004 Mustangs approximately 1-1/8" front; 3/4" rear.

Technical Note. These springs will not fit 1999 to 2004 SVT Cobra's with Independent Rear Suspension (IRS) or GT Mustangs converted to IRS.

Do I need to/should I buy the Isolators with it? I'm new to lowering springs, do I need to buy the Isolators or what?

Robert94 Year: 2000 Model: GT

  • The stock spring isolators will prove to be worn down and could even possibly be cracked due to the rubber that was used. New polyurethane spring isolators will last much longer than their stock counterparts, while offering improved handling, steering response and a quieter ride. Hope this helps!

Pinion angle Will lowering springs cause any problems by changing the angle to the rear pinion gear ? I have FR aluminum driveshaft & 3.73 gears.

mcgeadygt Year: 2001 Model: GT

  • No, I have the same gears and shaft setup. It aligns even better with the B springs.

    Amazing

    I just installed these spring as a replacement for my cut stockers. The difference is day an night even over 100% stock springs. The ride is much better than factory, but feels more responsive. The drop could be lower, but I also install ISOs. I seriously recommend these to anyone wanting to strictly improve handling and ride quality.

    Ride is much better. It is firmer, but not punishing at all (important on a convertible). Handling on curvy roads is now a blast. Springs have only been on a week. Car dropped about 1/2 an inch so far, but I'm sure some settling has yet to happen. Looking forward to more twisty driving. Haven't taken it on nasty city streets yet.

    Awesome Springs

    I put these in as a replacement for my cut stock springs and the ride is so much better. They could lower it more, but i left my isolators in and hopefully they will settle more. Anyways install was a breeze...rear end took 15 minutes and the front two took an hour and fifteen minutes. Great springs...looks lowered and wont scrape!!!

    From C to B

    I originally went from the stock spring to the C spring. These were way to stiff. After a little research I determined B was the way to go. These are a lot more road friendly. They greatly improved the ride quality over the C's. I do recommend these springs for a street driven mustang.

    Springs that work!

    When I purchased my 92 SSP foxbody about 2 months ago, it had Eibach lowering springs installed. Whoever installed those must have been going for the ultimate lowering as this was really too low! They were installed without the insulators as well, so metal to metal noises were heard. I was bumping things that shouldn't be bumping, so I called AM for advice about the setup. I'm sorry I don't remember with whom I spoke with, but his advice was spot on! My compliments AM for having such knowledgeable & helpful sales agents! He recommended the "B" springs for my ride, which confirmed my thoughts about replacements as well. Ford made the cars, so it seems their replacement parts are the most likely to work the best. I was not disappointed. The rear took me, by myself, about 2 hours to replace, but the front took me & 2 other helpers about all day to do! Those are not the easiest things to get in, but not because of the brand, it's just there are tricks to installing front springs, so you don't kill someone when they fly out unexpectedly! That didn't happen, but one must be careful. We ended up compressing the new springs with an internal compressor then chaining the springs to keep them in that state, making them easier to install. The first side took us 5-6 hours, while the second only about 40 minutes. The springs are worth the trouble though, as ride & handling are superior with these springs. My ride height was restored to an acceptable height, and now things don't bump. I was able to give them a good workout this past weekend while attending one of our club's cruises. The car is low enough now to give it a more aggressive look without the problems experienced with the Eibachs. Any springs purchased, but I recommend these, should be installed with the poly insulators! Thanks AM for such great sales help & delivery.

    Ford racing B springs

    Ford racing B springs gave my stang the handling and ride it needed over the stock springs, a excellent choice, it took me 4.5 hours to install by myself. The car drop 11/8" in the front and 3/4 in the rear. Very Satisfied.

    FRPP "B" Springs

    Used the "B" springs in conjunction with KYB Fox Body shocks/struts, MM Caster Camber Plates, MM Bumpsteer Kit, and X-2 Balljoints. Managed to lower the car 2"+ and ride comfort is excellent.

    Ford Racing B Springs

    I decided to go with these springs to replace the stock that were cut. Althought the drop isn't dramatic, I can't complain on the improvement for handling. I have these springs in conjunction with the KYB GR-2 struts/shocks, the ride is pretty firm. Over all I'm satisfied with this set up and recommened to those wanting a step up in handling if on a budget.

    Just right

    I thought about canceling my order after looking at the other 1.5 inch springs. I'm glad I went with these. With my 17 inch cobra wheels its a perfect stance. Doesn't look like a truck anymore, but doesn't scrape or look riced out. It looks awesome with the Mach 1 Chin spoiler too that I got on the same order. Highly recommend. It's pretty amazing what around 1 inch of drop will do.

    No fitment issues with Ford springs on a Mustang

    Nice drop on my GT. No rubbing or bottoming out. I have a convertible that has to be female rider friendly, so these offered a nice drop with the stock spring rates. I have MAC LT headers and subframe connectors and again no issue with bottoming out. If you haven't looked at them lately, consider either replacing your lower control arms (like I did) or at least replace the lower ball joint and bushings while you have the car apart.
