Total Cost Involved Engineering’s 1965-1970 Mustang Torque Arm rear suspension kit offers a unique approach to vastly improve your cars handling, cornering, braking and ride comfort. Popular on road race sports cars, the kit allows a lower ride height and rear axle control and turns your Mustang into performance touring car.
This kit will require the relocation of the single muffler to a pair of mufflers on both sides of the driveshaft just in front of the rear axle. The suspension kit is bolt-on and will require drilling holes (drilling will required: 1/2 inch, 3/8 inch and a 6˝ to 7 inch long 5/16 drill bit) except the coil- over/trailing arm brackets, rear anti-roll bar tabs, panhard bar bracket and torque arm tabs (location tool provided) which will need to be welded to a centered pinion, 9 inch Ford housing. Nine inch housings can be purchased from TCI in various stages with the brackets already welded on. Recommended width: Housing 51.5 inches, with axles 56.5 inches. I would highly recommend that before painting or powder coating the assembly components that you install the kit first then disassemble and paint or powder coat as desired.
The car has to be either on tall jack stands or preferably a hoist to facilitate removal of the exhaust system and old suspension components and the driveshaft. The carpet will have to be temporally removed in areas that the floor will be drilled through. The front and rear seats need to be removed to facilitate the installation. We used a body rotisserie to aid in the photography.
With all the old suspension removed, start by installing the rear inner sub-frame support plates (L&R) aligned with the front stock leaf spring hole using the ˝ inch by 6˝ inch bolts, washers and nuts that are furnished and lightly tighten.
The sub-frame connectors (L&R) are installed by bolting the rear hole of the connector with a ˝ inch by 3˝ inch bolt to the rear hole in the support plates to locate the front channel in the correct location before drilling holes.
Tap the sub-frame connector front channel over the stock frame rail until flush with the floor. Note: You may have to do a little hammer work on the stock frame rails to square them up to install channels. My 67 Mustang’s rails had taken quite a beating during the last 40 years.
