Upgrade your classic Mustang’s ride, handling, and stance with QA1’s Level 2 Full Vehicle Handling Kit. Engineered specifically for 1967–1970 Mustangs, this all-in-one system replaces factory suspension with modern coilovers, tubular control arms, a rear 4-link, and a QA1 9” housing — everything you need to transform your car into a refined, street-ready performer. MODERN HANDLING FOR CLASSIC MUSCLE Factory suspension setups simply can’t keep up with today’s power or driving expectations. QA1’s modern geometry and tunable coilovers deliver flatter cornering, better traction, and a smoother ride. The included 9” housing integrates directly with QA1’s triangulated 4-link, creating a rigid, unified rear suspension that’s built to handle power while keeping your Mustang comfortable and composed. HANDLING YOU CAN DIAL IN Double adjustable coilovers 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. BUILT STRONG FOR BIGGER CARS The 1967–1970 Mustangs are larger and heavier than their predecessors, so this kit includes 400 lb/in front springs for ideal balance and support. Combined with QA1’s tubular arms and 4-link rear, you get improved weight transfer, reduced body roll, and a more planted feel through corners. EASY INSTALLATION & SERVICEABILITY QA1’s front suspension bolts directly to factory mounting points, while the rear 4-link includes self-fixturing weld-in brackets that ensure perfect geometry and alignment. The QA1 9” housing arrives ready to install, complete with drain and fill plugs, vent port, and jack pad for simple servicing down the road.
