Detroit Speed Subframe Connectors (1964.5-1970 Ford Mustang) - 010105DS
Give your classic Mustang the stronger chassis foundation it deserves with the Detroit Speed 010105DS Weld-In Subframe Connectors. Designed for 1964.5-1970 Ford Mustang applications, these connectors tie the front subframe into the rear frame rails to increase chassis stiffness and reduce unwanted body flex. Their integrated weld-in design delivers serious structural reinforcement while maintaining the ground clearance and clean undercar appearance enthusiasts want from a performance-oriented street, Pro-Touring, or restoration build.
Detroit Speed fabricates the 010105DS connectors from 1.5 inches x 2.5 inches x 0.083 inch wall rectangular steel tubing. Front frame rail saddles and end caps are incorporated for additional strength and stiffness, while each connector is bent and TIG welded in a fixture for accuracy and repeatability. At the rear, the connectors attach to Detroit Speed torque boxes supplied with the Mustang QUADRALink or Mustang Mini-Tub Kit, creating an integrated structural connection through the chassis.
One of the biggest advantages of the Detroit Speed design is how cleanly it fits the Mustang. The connectors are barely visible from underneath the car and are engineered to maximize ground clearance compared with traditional bolt-on designs. They do not interfere with the factory seat attachment hardware or installation and removal of the rear leaf spring pocket. They can also be installed on convertible Mustangs, and the factory molded carpet can still fit over the connectors after installation.
Important fitment note: If your Mustang is not being equipped with the Detroit Speed Mustang QUADRALink or Detroit Speed Mustang Mini-Tub Kit, Detroit Speed stock-suspension torque boxes, P/N 010109, are required and must be purchased separately. Installation templates and detailed instructions are supplied with the subframe connectors.

FAQs
Do I need Detroit Speed torque boxes to install the 010105DS Subframe Connectors?
The rear of the 010105DS connectors attaches to Detroit Speed torque boxes. If your Mustang is being equipped with the Detroit Speed QUADRALink or Mustang Mini-Tub Kit, the appropriate torque boxes are supplied with those systems. If neither system is being installed and the car retains the stock rear suspension, Detroit Speed P/N 010109 torque boxes must be purchased separately.
Will these subframe connectors reduce ground clearance or interfere with the Mustang's interior?
Detroit Speed designed the 010105DS connectors to remain barely visible from underneath the car while maximizing ground clearance. They do not interfere with the factory seat attachment hardware, and the factory molded carpet can still fit over the connectors after installation.
