Overview

Give your 2015+ Mustang the proven performance of Steeda manufactured suspension parts. This Steeda Stage 3 Handling Package for your S550/S650 Mustang GT, EcoBoost, or V6 is designed to provide better handling characteristics, increase traction, and reduce wheel hop.

Steeda’s Stage 3 Handling Package for your Mustang includes Steeda Adjustable Rear Toe Links to improve the handling characteristics and improve vehicle’s overall handling response. These toe links have a large range of adjustability and can be done with uninstalling them.

Our Steeda Vertical Links are far superior to the stock vertical links on your S550/S650 Mustang. They feature billet steel bushing sleeves and spacers, providing less deflection than the rubber bushings in the stock links without increasing NVH. The strength of the billet that the Steeda Vertical Links are made of will provide a more solid feel to your suspension and will not flex under load.

Why Steeda
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.

QS-9000 & ISO 9001 manufacturing · Limited lifetime warranty on Steeda-manufactured parts · Made in the USA

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.
