Designed specifically for 1964–1966 Mustangs, this system replaces outdated factory suspension with a complete bolt-on package - engineered for balance, adjustability, and ride comfort.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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDouble adjustable QA1 Pro Coil shocks allow independent compression and rebound tuning\u003c\/li\u003e\n\u003cli\u003eFabricated QA1 9” housing with 31-spline 1541H alloy axles rated up to 650 HP\u003c\/li\u003e\n\u003cli\u003eTubular upper and lower control arms for better geometry and steering response\u003c\/li\u003e\n\u003cli\u003eFront and rear sway bars reduce body roll and improves cornering response\u003c\/li\u003e\n\u003cli\u003eBig Ford “New Style Torino” flanges for brake compatibility\u003c\/li\u003e\n\u003cli\u003eHeavy-duty 3” OD ¼” wall axle tubes handle up to 800 HP\u003c\/li\u003e\n\u003cli\u003eComprehensive instructions for straightforward installation\u003c\/li\u003e\n\u003cli\u003eRear triangulated 4-link eliminates axle wrap and wheel hop\u003c\/li\u003e\n\u003cli\u003eComplete front and rear suspension solution in one kit\u003c\/li\u003e\n\u003cli\u003eApplication-specific fit for 1964–1966 Ford Mustangs\u003c\/li\u003e\n\u003cli\u003e5x4.5” bolt pattern fits a wide range of wheels\u003c\/li\u003e\n\u003cli\u003eAdjustable front ride height: stock to –2”\u003c\/li\u003e\n\u003cli\u003eAdjustable rear ride height: stock to –3”\u003c\/li\u003e\n\u003cli\u003eDurable black powder coat finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis Part Fits:\u003c\/p\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" width=\"100\"\u003eYear\u003c\/th\u003e\n\u003cth align=\"left\" width=\"125\"\u003eMake\u003c\/th\u003e\n\u003cth align=\"left\" width=\"150\"\u003eModel\u003c\/th\u003e\n\u003cth align=\"left\" width=\"80\"\u003eSubmodel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1964-1966\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eMustang\u003c\/td\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1965-1966\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eMustang\u003c\/td\u003e\n\u003ctd\u003eShelby GT-350\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1966\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eMustang\u003c\/td\u003e\n\u003ctd\u003eShelby GT-350H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"QA1","offers":[{"title":"Default Title","offer_id":52314501873983,"sku":"QAPHK02-FM01RS","price":8369.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/2041\/6831\/files\/14992a552b1a9457bb3f9101f17a6fe5L_2c228bea-8022-4746-a2ff-d4d876fcdc30.jpg?v=1773427956","url":"https:\/\/smgspeed.com\/products\/qa1-64-66-ford-mustang-handling-kit-level-2","provider":"SMGspeed","version":"1.0","type":"link"}
