Overview

Steeda’s S550/S650 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.

The kit is comprised of our Mustang suspension components that helped us achieve the record at the drag strip. This kit helps you get traction at the track and stop the wheel hop that you experience when launching your IRS equipped Mustang. By preventing wheel hop, you are able to launch harder and accelerate faster so that you can achieve better times down the 1/8th or 1/4 mile.

First is our Alignment dowel kit. This fills the factory bolt hole voids with CNC machined Delrin inserts that will square up the rear subframe to the chassis. By filling these voids we are also limiting the side to side and front to back movement of the subframe that is present under hard acceleration and braking.

The leader in Ford performance.

Steeda has been engineering and manufacturing Ford performance parts in-house in Valdosta, Georgia for over 35 years — proven on their own SCCA Majors race team and trusted by enthusiasts who live and breathe Ford. CNC-machined billet construction, proprietary CAD-driven suspension geometry, and a relentless focus on the platforms they specialize in.

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.
