Step 2. Select your Shocks/Struts
Steeda Pro-Action Adjustable Shocks & Struts - Adjustable
These dampers feature street and track-proven technology which have been methodically tested and tuned to achieve optimum compression valving, giving you that quick sports car reaction on the road with easily adjustable rebound damping at the twist of a knob. From soft and comfortable to stiff and aggressive, these Pro-Action shocks have more adjustability than you will ever need!

Steeda Pro-Action Non-Adjustable Shocks & Struts - Non-Adjustable
Looking for a cost effective alternative to adjustable shocks and struts? Here is the answer. Steeda's new Pro-Action fixed valve shocks and struts for the S550 Mustang GT, V6 and EcoBoost. Steeda's Pro-Action shocks and struts were engineered by Steeda and manufactured to provide the ultimate in ride quality and handling while exceeding OE standards for durability and build quality. Pro Action shocks and struts come with a limited lifetime warranty against manufacturing defects and are perfect for daily street driving or open track use.

Steeda Active Shocks & Struts - Non-Adjustable
These are dampers made for daily drivers that see occasional track usage. They will provide the best ride possible due to their patented frequency selective damping technology.

Step 3. Shock Mounts

Made from billet 6061 aluminum, these mounts are designed to replace the weak cast factory units. Unlike the factory mounts that have a rubber bushing that binds and will deteriorate over time on lowered cars or cars with aggressive shock settings, these units feature a Steeda spec stainless steel spherical Teflon lined bearing for optimum performance and control. Steeda also designed this kit to provide 1/4 more clearance for wide rear tires!

Note: When selecting a shock mount, adjustable shocks and struts must be paired with the adjustable shock mounts for proper fitment. When selecting a shock mount, non-adjustable shocks and struts must be paired with the non-adjustable shock mounts for proper fitment.

Step 4. Camber Plates
Our Steeda S550 Mustang Camber Plates for Mustang GT, EcoBoost, and V6 are great for both street and track use. Our camber plates come into play especially when lowering your vehicle. With the addition of our new adjustable strut mounts on your lowered 'Stang you will be able to correct excessive negative camber and increase your front steering response. If you lowered your daily driven S550 Mustang, running the correct camber will eliminate uneven tire wear.

We highly recommend Camber Plates for any 2015-2018 Mustang for proper alignment and the best performance.

Step 5. Bumpstops
Designed and engineered in-house specifically for the S550 Mustang, these bumpstops are made from high-impact polyurethane which make them stiffer than factory and prevent damage to the shocks, and other suspension components. The adjustable feature gives the customer the ability to use the kit on a stock or lowered ride height vehicle. This means no trimming of the factory bumpstops in order to maintain a safe and quality ride on lowered vehicles.

Step 6. Pre-Assembly
Have your suspension kit Pre-Assembled and ready for installation without the need for expensive specialty tools. Includes Strut Bearing, Dust Cover, and Spring Isolator. Assembly is performed by Steeda Technicians. Your new suspension package is shipped, ready for a quick installation using basic tools.

Note: For fully assembled kits, shock mounts, camber plates, and bumpstops are required. For front only assembled kits, camber plates and bumpstops are required. For rear only assembled kits, shock mounts and bumpstops are required.
Note: Please contact us for MagneRide equipped vehicle applications.

Note: Lowered amount may vary from car to car depending on vehicle package and trim options.
