Slay Corners with QA1 Suspension Upgrades for 1964-70 Mustang

As good as your 1964-70 Mustang was in the handling department back in the day, a lot has changed in the 60 years since it hit the streets. Enter QA1. Their full lineup of control arms, subframe connectors, sway bars, rear axles, four link kits, and full suspension kits will significantly improve your Mustang’s performance around the curves.

Subframe Connectors
QA1 Subframe Connectors tie the front and rear subframes together to improve chassis rigidity, reduce body twist, improve traction, and provide a stable platform for other suspension upgrades to work effectively. QA1’s subframe connectors are made from tubular steel for maximum strength with minimal weight. They bolt directly to the chassis with no modifications.

Sway Bars
With your chassis appropriately stiffened, the next items on your improvement list are QA1 Sway Bars. These direct bolt-on bars reduce body roll, improve steering response, and make your car feel planted in the corners. They are available for front and rear, and should be used together to maximize handling improvements. Polyurethane bushings and mounting hardware are included.

Tubular Control Arm Kits
That brings us to QA1’s Tubular Control Arm Kits. These bolt-on upper and lower control arms eliminate the flex inherent to the factory stamped arms, sharpening steering response and allowing for performance-oriented alignment adjustments. The tubular steel construction also reduces unsprung mass by up to 15 pounds, allowing the suspension to react faster to road conditions while providing superior durability. They come pre-assembled with maintenance-free, greaseable ball joints and polyurethane bushings. They will work with the factory spindles and require the use of QA1 Pro Coilover Shocks.

Four Link Rear Conversion Kits
QA1 has plans for the rear of your Mustang, too. Their Four Link Conversion Kits replace the outdated factory leaf springs with a modern, triangulated adjustable suspension. This eliminates the axle wrap, lateral movement, and wheel hop inherent to the OEM rear suspension to dramatically improve handling, traction, and ride quality.

The kits allow precise ride height and damping adjustments, giving you the option to lower your car up to three inches. The complete kits include your choice of single or double adjustable Pro Coilover shocks, trailing arms, bushings, brackets, hardware, and links. Some welding is required for installation.

Level 1 and Level 2 Full Vehicle Handling Suspension Kits
Want to do all the upgrades at once? QA1 has you covered with the Level 1 and Level 2 Full Vehicle Handling Suspension Kits. These all-in-one kits include everything you need and nothing you don’t to get the performance you’re craving.

Level 1 kits are for owners of daily drivers, restomods, and weekend cruisers. The true bolt-on systems allow you to adjust the front ride height from stock to minus two inches while delivering improved handling and a balanced, more comfortable ride. Level 1 kits include tubular upper and lower control arms, a front sway bar kit, single adjustable Pro Coilover front shocks, and Stocker Star rear shocks.

Level 2 kits are designed for hot street, Pro-Touring, and track-day enthusiasts looking to extract every bit of grip out of their car. They have basically every upgrade available from the QA1 catalog:

• Tubular upper and lower control arm kits
• Double adjustable Pro Coilover front shocks
• Subframe connectors
• Front and rear sway bar kits
• Four link rear conversion kit with double adjustable Pro Coilover shocks
• Available with or without the Ford 9-inch rear axle assembly

Ford 9-Inch Rear Axle Assemblies
A QA1 Ford 9-Inch Rear Axle Assembly can handle more horsepower and the high-G loads that your new QA1 suspension upgrades can generate. The axles are designed to bolt-in seamlessly with the Four Link kits, eliminating the need for cutting, welding, or fabrication work. Features include:
