Overview

Steeda’s S550 Drag Pack for 2015+ Mustangs is the ultimate suspension kit for the drag strip. Featured on our 2018 world-record-setting, 10-second 2018 Mustang GT, this kit ensures your Mustang stays firmly planted for a more powerful launch.

This kit is comprised of our S550 Adjustable Front Coilover system, 150lb / 12″ Front Drag Springs, Adjustable Front Camber Plates, Rear Drag Swaybar and Adjustable Camber arms to plant your rear tires even, every time. The Front Drag Springs are a perfect match when running our Rear Drag Springs on the rear of your car, keeping it firmly planted for maximum traction without compromising ride comfort. Additionally, the Adjustable Front Shocks offer optimum compression valving, giving you that quick sports car reaction on the road with easily adjustable rebound damping at the twist of a knob. Lastly, Rear Adjustable Camber Arms and Drag Rear swaybar keeps your tires and launches flat every time to help eliminate wheel hop in the S550 Mustang.

First-hand note

FFP fits Steeda parts every week in Thousand Oaks.

— Why we stock Steeda

OE-style engineering, in-house manufacturing, race-proven on Steeda's own SCCA program.

Steeda has been engineering Mustang — and now Explorer, Focus, F-150, and Maverick — parts in Valdosta, Georgia since 1988. CNC-machined billet, proprietary CAD-driven suspension geometry, and a factory SCCA Majors road-racing team that runs their own parts on the track every weekend. When you bolt a Steeda part onto your car, it's the same part Steeda's own race cars run.

We carry Steeda because the fitment is right the first time, the warranty is real (lifetime on Steeda-manufactured parts), and the install instructions don't leave you guessing. Drop the car at our Thousand Oaks shop and our techs handle the fit-up — or order with confidence and run it yourself.
