The Detroit Speed Fox Body Mustang Adjustable Track Bar Kit adds a critical link to keep the rear axle stable during hard cornering. The factory 4-link is completely ineffective at locating the axle side-to-side as the suspension arms travel vertically. The addition of a Detroit Speed Track Bar to the Fox Body Platform will prevent the axle from wandering unpredictably. The track bar connects the rear axle to the chassis of the vehicle, which helps keep the axle centered under the chassis during suspension travel. This gives the driver better grip and acceleration off the line and more confidence in the corners. The track bar brackets attach utilizing holes added into the frame rail as well as U-bolts to the factory 8.8 rear axle.
