Transform your classic Mustang into a modern-handling street machine with QA1’s Level 2 Full Vehicle Handling Kit. Designed specifically for 1964–1966 Mustangs, this system replaces outdated factory suspension with a complete bolt-on package - engineered for balance, adjustability, and ride comfort. From the front control arms to the rear 4-link and 9” housing, every component works together to deliver sharper steering, better traction, and a perfectly tuned stance. MODERN PERFORMANCE, CLASSIC STYLE Factory leaf springs and stamped steel components limit performance and ride quality. QA1’s complete suspension system updates your Mustang with modern geometry, adjustable coilovers, and tubular construction that drastically improves handling without compromising ride comfort. The included 9” housing integrates seamlessly with QA1’s triangulated 4-link to create a unified, high-strength foundation ready for serious power. HANDLING YOU CAN DIAL IN This Level 2 system includes double adjustable coilovers that allow independent control over compression and rebound, so you can fine-tune ride quality and performance for your exact driving style - whether that’s highway cruising or weekend corner carving. FRONT-TO-REAR BALANCE The included tubular upper and lower control arms, front sway bar, and fully adjustable rear 4-link work together to control body roll and maintain optimal suspension geometry. The result is a Mustang that corners flatter and accelerates smoother. BUILT FOR POWER AND RELIABILITY The included QA1 9” fabricated housing delivers exceptional strength and serviceability. Featuring heavy-duty 3” OD ¼” wall axle tubes, 31-spline alloy axles, and formed trailing arm brackets, it’s rated up to 800 HP - giving you peace of mind whether your build is mild or wild.
