QA1 Level 3 Full Vehicle Drag Kit (DK43-FMM1) - 1979-1986 Ford Mustang
Take your Fox Body to the highest level of drag racing performance with the QA1 Level 3 Full Vehicle Drag Kit. Designed for 1979-1986 Mustangs, this top-tier suspension system delivers maximum adjustability, improved weight transfer, and superior chassis control for serious racers looking to push their setup to the limit.
At the core of this system is a lightweight tubular K-member that reduces front-end weight while improving geometry and engine bay clearance. Double adjustable front coilovers paired with QA1 MOD Series rear coilovers provide unmatched tuning capability, allowing you to fine-tune compression and rebound for optimal launch and track performance. Combined with tubular control arms, boxed trailing arms, and a rear sway bar, this kit minimizes flex, improves traction, and keeps your Mustang launching straight and consistently.
