TCI Engineering’s 1964.5-1970 Ford Mustang Triangulated 4-Link Rear Suspension provides excellent handling through superior geometry and lowered center of gravity. Better handling, minimum weight, and greater axle control are just the beginning. Retaining street manners and comfort while providing excellent trackability all in one package.

The tight spaces of the early Mustang body create some packaging challenges for the upper link bars length.  Therefore, our engineers went outside the box and were able to make a longer link bar by mounting it well behind the axle housing. For this reason, it will keep pinion movement to a minimum and axle control to a maximum. There are 3 height adjustments on the axle brackets in one-inch increments. You also have the ability to fine-tune the ride height further with the adjustable coilovers. This 1964.5-1970 Ford Mustang Triangulated 4-Link kit eliminates bind common with parallel 4-link bars by angling the upper link bars inward. The Panhard bar is eliminated from the equation in this instance to provide more weight savings.

The installation of the 1964.5-1970 Ford Mustang Triangulated 4-Link Rear Suspension mostly requires drilling and bolting in components. The only welding required is 4 tabs on top of your axle housing for the upper link bars. We provide detailed instructions plus a fixture to properly attach the housing tabs. The optional anti-sway bar will require brackets to be welded onto the axle housing as well. The kit is available for 8” and 9” axle housings. Please specify at the time of ordering. Complete 9” axle housings are available fully welded and ready to be bolted in.
