The beloved Fox Body Mustang has been a staple of the motorsports world since it first broke cover in the late 1970s. And while its on-track prowess is certainly well documented, the suspension experts at QA1 realize that there’s always room for improvement.
…Which is why they offer a veritable smorgasbord of handling upgrades for the Ford Fox platform, and they made sure everyone who walked down the Manufacturer’s Midway during the 2026 Hot Rod Power Tour knew about it:
Displayed in a set of dissected Fox Body shock towers, QA1 showcased several of its most vital Mustang suspension upgrades, notably its shock/strut assembly, K-member, and sway bar.
And like many things the QA1 folks do, these parts aren’t assembled in a vacuum—each component is designed to play nice with the rest of the suspension system to avoid any fitment, interference, or incompatibility issues moving forward.
The best part is, QA1 bundles these parts together, yet also makes select pieces available separately. That way, you can either purchase an individual part and build as your budget allows, or get your Fox’s suspension upgrade done in one fell swoop with a complete Mustang handling package.
As many Fox Body aficionados already know, there are a few key distinctions along the Fox platform’s decade-plus run, so QA1 breaks it down by era:
- 1979-86
- 1987-89
- 1990-93
Long story short, make sure you know exactly which chassis you have before you order. Once you do, Summit Racing makes it really easy to find parts thanks to its year/make/model search filter at SummitRacing.com.
