Stiffen up your classic Mustang’s chassis with QA1’s tubular subframe connector kit. Designed for 1964–1970 Mustangs, this bolt-on upgrade ties the front and rear subframes together, reducing chassis flex and improving overall handling performance. Perfect for street cars, restomods, and track builds, QA1 subframe connectors make your Mustang feel more solid and responsive. STRENGTHEN YOUR MUSTANG’S FOUNDATION Classic Mustangs are known for body flex, especially when cornering or under hard acceleration. QA1’s tubular subframe connectors solve this by creating a rigid connection between the front and rear frames. The result: more predictable handling, reduced squeaks and rattles, and improved traction for modern driving demands. EASY INSTALLATION These connectors are engineered for a true bolt-on installation with no need to cut into the floorpan. They are built to work with the QA1 4 link suspension and fit tightly to the frame rails for maximum rigidity.
- Application-specific fit for 1964–1970 Ford Mustangs with QA1 4 link rear suspension
- Designed to work with QA1 suspension upgrades for a complete system
- Tubular steel construction for maximum strength with minimal weight
- Enhances traction and stability during acceleration and cornering
- Durable black powder coat finish for long-lasting protection
- Bolt-on installation - no cutting into the floor required
- Reduces chassis flex and improves handling response
