In the world of Mustang, choosing the right springs for handling, body roll, ride height, and usage will determine the performance outcome of your stallion. For over thirty years, Steeda has been the number one manufacturer in the automotive aftermarket leading the way to help enthusiasts take full potential of their Mustang. Ever since the S550 Mustang launched in 2015, it has been leading the charge among all modern American muscle cars to provide the best performance, handling, and functionality to all enthusiasts. From the factory, it is the most capable Mustang right out of the box in comparison to any of its predecessors before; unlike previous Mustang generations, it is the first Mustang ever to come equipped with IRS (Independent Rear Suspension) standard.

This innovation of engineering helped bring the Mustang into the twenty-first century; to help it compete better amongst its rivals from Europe and abroad. It enabled the Mustang to be more nimble, ride smoother, and corner harder due to each wheel being independent of one another, allowing smoother feedback to the driver. Unfortunately, just like Mustang models of previous years, the S550 still deals with issues of stance, ride quality, and body roll.

These variables are where Steeda's experience, knowledge, and engineering come into play to help enthusiasts take full potential of their Mustang.

Steeda Progressive Springs

Chances are if you're an enthusiast who loves the ability to have a great ride height, quality ride, and handling, you are going to want to pick up our Progressive Sport Springs. These springs are our most popular option due to their characteristics of allowing enthusiasts to have all the attributes of OEM springs, while enhancing performance even further. Our progressive springs offer different variable spring rate from one side to the other; this means it will give you exceptional ride quality cruising down your favorite highway with minimal travel, while maintaining performance on that twisty backroad.

The signature difference in our Progressive springs vs Linear springs is simple. They offer more resistance to body roll due to the precise spring rates we have engineered throughout the coils. These springs will allow every Mustang enthusiast to enjoy a weekend track day or carve up your favorite mountain road at a moment's notice. The word progressive means it will have a constantly increasing rate, which relates to the spacing between each coil on the spring itself. We advise you to purchase this spring if you want to have the best of all worlds in one spring.

The most common Mustang spring out in the marketplace today is the Linear Spring; this spring is the type where one continuous spring rate is seen through the compression cycle. Unlike the progressive spring where the spring rate can change, a linear spring has one linear motion hence why it is called linear. Most enthusiasts who choose to use this spring are wanting to use it for one purpose that could be road racing or drag racing. If you want a more direct feel and feedback throughout the compression of the spring when driving, then these are going to be for you.

Whereas the progressive spring will offer you a much better quality ride over the stock OEM springs, a linear spring can be a much harsher ride depending on the spring rate you choose. Steeda linear springs are fantastic for multiple types of racing because of the direct feedback they offer when you input variations of steerings and throttle. Other benefits of linear springs include decreased nose dive when braking, sharper steering response, and a lighter weight over the factory springs.

This spring is solely designed to have two different springs rates throughout the entire coil pack.
