    Improves Handling. Are you looking for an inexpensive way to improve the handling performance of your 1979-2004 Mustang? If so, you should upgrade to a set of SR Performance Linear Lowering Springs. These Springs were engineered to lower your Mustang's center of gravity, which will helps to reduce squat during rapid acceleration, body roll in the corners, and excessive nose-dive under hard braking. SR Performance Linear Lowering Springs are ideal for daily driving, street, and even occasional track use.

    Sleek Lowered Stance. A set of SR Performance Springs not only improve the handling performance of your Mustang, but they also improve its overall appearance. By lowering the ride height approximately 1.5" front and rear, that huge tire to fender gap is eliminated. These Springs will provide your Mustang with a sleek, muscular stance that will be sure to get you noticed on the street and at the track.

    Linear Design. Linear springs (also known as standard rate springs) are engineered with a constant spring rate that remains the same as the spring compresses. This linear rate of compression allows for optimum traction and a more predictable handling feel at both low and high speeds. Linear springs will have a slightly rougher ride when compared to progressive springs. Linear rate springs are a popular choice for track and road course driven Mustangs. 460 lb/in - Front; 280 lb/in - Rear

    Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your stock 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.

    Professional Installation Recommended. Seeing that a spring compressor is required for installation of these Lowering Springs, AmericanMuscle recommends professional installment. With the proper tools, the install can be completed in about three hours. Please note that an alignment is highly recommended after installation.

    Recommended Upgrade. When installing new Springs on your Mustang, you should also replace your old worn out rubber Spring Isolators with a new set of Polyurethane Spring Isolators at the same time, see ordering options above.

    Application. This set of four SR Performance Linear Lowering Springs are specifically designed for use on 1979-2004 Ford Mustang coupes, including the LX 5.0, V6, GT, Bullitt, Mach 1, and 1993-1998 SVT Cobra models. Does not fit 1999-2004 IRS-equipped SVT Cobras.

    Seen reviews and pics about these springs "lifting" the car. Which set would actually lower my v6 coupe?

    • The SR Performance Linear Lowering Springs will lower the vehicle approximately 1.5" all the way around. These springs are not manufactured or intended to raise the vehicle.

    Helpful (0)

    Will these work just as good with a v6 as well as a v8? I noticed that a different set of springs wouldn’t give a v6 as much of a drop as a v8 because of the weight difference.

    • The SR Performance Linear Lowering Springs work on all 79-04 models excluding 99-04 Cobra.

    Helpful (0)

    I’m confused. Why won’t these work on a convertble? The Ford C springs listed on this same page work on both convertble and coupe. Why are these listed as “not” working with convertible?

    • The SR Performance Linear Lowering Springs are designed specifically for the weight distribution of the coupe, and would not perform well and would not give the advertised lowering amount on the heavier convertible models. The Ford Performance C Springs were designed with both Coupe and Convertible models in mind allowing these to perform adequately on either model.

    What makes these springs not work for a 03 v-6 convertible?

    • The SR Performance Linear Lowering Springs are designed for the weight and weight distribution of coupe models. A convertible's weight distribution will be different, making these springs perform poorly.

      Sr spring suck

      The front dropped awesome. Back didn't move almost seems like it got higher. Tried to settle car. Put spring bottom pigtails in varrious postision including the right way with both at the back faceing drives side nothing made a difference. Borrowed a set or eibach sport 1.5" rear drop put them in and car is sitting almost level with the front like it was supposed to drop with the 1.5" all at spring. Not happy I bought a kit and now need to buy different rear springs or a proper lowering kit. Not impressed with Sr preformance or American muscle.

      Lowering a 2000 GT Mustang?

      Well the ad says that they'll lower an inch and a half front and rear. But whenever I install the springs it lowered it and inch and a half in the front but did not lower it at all in the back why is that I do not know and I would like to understand why not so now I will have to either cut these in the rear and make them the length i want or buy another rear set of Springs I prefer people not to buy the linear lowering springs because they did not lower the rear end of my car at all

      Lowering springs

      I installed theses springs along with a set of rest lower control arms. I've been riding for a couple of days now and the only downsides so far is that the front is tucking and my rear barely dropped; but so far it handles and rides way better than before.

      Makes my car look lifted.

      These were supposed to lower my car roughly 1.5 inches. Instead, I had them installed and it sits higher than it did before. I think it looks terrible and not at all happy with the outcome. Very disappointed in these. Wouldn't recommend to anyone. The only plus side to this is it rides a little better. But not worth the price at all.

      not enough drop

      I installed these springs and was not satisfied with the drop. When I installed them I didn't see much of a drop and just thought they needed time to settle ,but they didn't get much lower. It probably only dropped it about an inch.

      Ride quality definitely better. Easy install and a real bang for your buck. Needed something temporary while I save money up for air lift and I can say I’m thinking about keeping these on longer. Love at performance
