Ford Fox-body vehicles were designed in the mid-1970s with a great importance on saving weight. America had just gone through a gas crisis and economy was on everyone’s mind. This meant the Mustang (and other Fox vehicles) was getting a compact design and the unitized Fox-body fit the bill. It allowed for the popular modified MacPherson strut front suspension that used a bolt-in stamped steel K-member, with lower A-arms, separate coil springs and struts that connected the spindles to the strut towers in the chassis. The front combined with a non-parallel four-link rear, where the springs ride on the lower control arms. This arrangement was very basic, using stamped steel arms with rubber bushings to connect the rear end housing to the chassis. Most importantly, the design enabled Ford (and Lincoln/Mercury) to use the chassis for a wide range of vehicles.
The suspension/chassis setup worked well for the time, but can be greatly enhanced for performance and longevity with aftermarket components. As horsepower or torque is added, the chassis will likely flex. A close inspection of a high-mileage Fox may reveal cracks in critical areas, such as the rear suspension pick-up points. Despite this, you can affordably stiffen the chassis of your Fox by adding a set of frame connectors.
An affordable option is the BBK Gripp Mustang Sub-Frame Connector kit. These frame connectors add strength to the structure and help resist flex. BrothersPerformance.com offers a variety of sub-frame connector kits for all 1979 to 2004 Mustangs.
The Gripp connectors are made from boxed steel and can be bolted in or welded for extra strength. And like we stated, they are a must for any on-track activities including drag racing, road racing, competing in autocross, or just driving your Mustang aggressively around town. Stiffening the chassis will also help to keep your Mustang aligned, and another bonus is that your doors and will open and close more smoothly.
BBK’s connectors come in a Charcoal gray metallic powdercoated finish that’s attractive and durable. And they are made right here in America.
