Purpose built for QA1 rear coilover conversions and designed to match the performance of QA1’s front sway bars and suspension systems, this rear bar reduces body roll, improves traction, and helps your Mustang corner with confidence. A bolt on upgrade to the QA1 4 link kit for unlocking even more potential. BALANCED HANDLING \u0026amp; STABILITY Adding a rear sway bar is one of the most effective ways to improve cornering performance on a classic Mustang. QA1’s tubular 0.875” sway bar increases roll stiffness at the rear axle, reducing understeer and keeping your car more level in the turns. The result is sharper handling, more predictable grip, and a Mustang that feels planted and controlled. BOLT-ON INSTALLATION This kit is designed for straightforward installation, bolting directly to the QA1 4 link crossmember with no cutting or welding required. It includes polyurethane bushings and heavy-duty mounting hardware for a complete, ready-to-install solution.\n1964-1970 Ford Mustang\nFITMENT NOTES: Fits 1964–1970 Ford Mustangs: Works exclusively with QA1 rear coilover conversion 4 link kits – will not work with factory leaf springs or other manufacturers suspensions: Complements QA1 front sway bars for a balanced setup\n\u003cul\u003e\n  \u003cli\u003eApplication-specific fit for 1964–1970 Ford Mustangs with QA1 rear coilover conversion 4 link\u003c\/li\u003e\n  \u003cli\u003e0.875” (7\/8”) tubular construction for lighter weight and added strength\u003c\/li\u003e\n  \u003cli\u003eDesigned to complement QA1 front sway bars and suspension upgrades\u003c\/li\u003e\n  \u003cli\u003eEnhances traction and stability under acceleration and cornering\u003c\/li\u003e\n  \u003cli\u003eReduces body roll and improves overall cornering balance\u003c\/li\u003e\n  \u003cli\u003eIncludes polyurethane bushings and hardware\u003c\/li\u003e\n  \u003cli\u003eDurable black powder coat finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eImprove the handling and cornering balance of your classic Mustang with the QA1 QAP52900 rear sway bar kit.
