    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. Does Not Fit Convertible models.

        5 Top Rated Questions

        it says does not fit convertible models why is this ?

        • Due to the difference in weights between coupe and convertible these are listed to only fit coupes. While theSR Performance Linear Lowering Springs will install with convertibles you may notice a different drop than advertised.

        What are the lengths of the springs when not compressed? And what are the spring rates?

        Do you need to install the spring isolators?

        I have the SR Performance lowering springs and was wondering after installing them, can you fit without rubbing a 18x9 wheel with 265x35r18 tire in the front?

        • You can fit this tire size without rubbing yes.

            Good buy for the price.

            Slightly harder ride due to standard rate springs, but less body roll in corners for the same reason. More predictable cornering. Ride height gets rid of stock fender gap, but I have yet to scrape anywhere during daily driving. bought these on sale and it was a great purchase.

            basically a lift kit

            The rear springs lifted my car, which I heard about in a few other reviews. I ended up comparing the OEM spring to the aftermarket SR performance linear lowering spring and the SR spring was bigger. Ended up cutting the rear springs and front springs. Just pay the extra money and get a set of eibachs. the springs improved handling at least.

            As advertised

            These spring arrived on the quoted day through UPS. It was helpful to have the instal video on AM. For the 04 GT the rear instal is a bit different then the video showed, I removed the rear sway bar and decompressed the springs by lowering the rear of the control arms very carefully since the springs are under tremendous pressure and can shoot out which could be dangerous. These springs definitely lowered the vehicle at least 1.5 inches all around after driving a few hundred miles I really noticed the appearance difference. Also these springs lowered the cars center of gravity making turns feeel nice and tight and secure.

            Progressive and linear sr springs

            I’ve been working on mustangs since the 79 fox my last 5 have been 99-04 gt’s ive tried both springs and although not the best ride but definitely works well and have always dropped the cars 1-1.5” front and rear I do always use new isolators but all my cars have sat low and handled really well after installing just remember the adjustable caster/cambers in the process

            Coupled with tubular rear control arms these springs went in easily and fit perfectly. Lowered suspension as advertised and gives a firm ride great for a little tighter cornering. Nice price as well.
