Detroit Speed Rear Torque Box Kit - Stock Suspension (1964.5-1970 Ford Mustang) - 010109DS
Add critical structural reinforcement to your classic Mustang while retaining the factory-style rear suspension with the Detroit Speed 010109DS Rear Torque Box Kit. Designed specifically for 1964.5-1970 Ford Mustang applications with stock rear suspension, this kit strengthens the rear chassis structure and is engineered to work with Detroit Speed 010105 Subframe Connectors. Together, the torque boxes and subframe connectors create a stronger foundation for performance-oriented street cars, restorations, and Pro-Touring builds that continue to use the stock rear suspension configuration.
The 010109DS torque boxes provide the rear attachment structure for the Detroit Speed subframe connectors. Rather than simply adding reinforcement underneath the car, the torque boxes become part of the chassis structure, helping increase rigidity where the subframe connectors meet the rear frame rail area. Detroit Speed specifically engineered this version of the kit for stock rear suspension applications, making it the correct torque box configuration when installing Detroit Speed subframe connectors without converting to the company's QUADRALink rear suspension.
Detroit Speed's installation design integrates the torque boxes with the factory front leaf spring mounting area. The 010109DS configuration includes application-specific hardware used to properly locate and reinforce the torque box assembly, including frame rail and body bracket crush tube provisions. Installation requires welding to create a permanent structural connection with the Mustang chassis.
Important application note: The 010109DS kit is specifically designed for Mustangs retaining the stock rear suspension. It should not be confused with Detroit Speed 010107DS, which is the rear torque box configuration intended for Mustangs using Detroit Speed rear suspension.
