DSE Adjustable Rear Track Bar Kit (042111DS) - 1979 - 1993 Ford Mustang / 1979 - 1986 Mercury Capri
Take control of side-to-side rear axle movement with the DSE Adjustable Rear Track Bar Kit 042111DS. Engineered specifically for 1979-1993 Ford Mustang and 1979-1986 Mercury Capri applications, this Fox Body suspension upgrade adds the lateral axle control missing from the factory four-link arrangement. By connecting the rear axle directly to the chassis, the Detroit Speed track bar helps keep the axle centered as the suspension moves through its travel, giving the driver greater stability, better grip, and more confidence under hard acceleration and aggressive cornering.
Detroit Speed engineered 042111DS as a direct bolt-on package featuring cross-axis pivot bushings and an adjustable track bar that can be fine-tuned without unbolting it from the vehicle. Two mounting-hole locations accommodate different vehicle ride heights, while the track bar geometry locates the rear roll center 1.5 inches below the axle centerline to improve handling. Laser-cut brackets work with the original frame and factory 8.8-inch rear axle, and the body-side and axle brackets are powder coated black. The system can also provide clearance for custom exhaust up to 3 inches depending on tire width, mini-tub width, and fuel-tank configuration.

Fitment Notes
DSE 042111DS is designed for 1979-1993 Ford Mustang and 1979-1986 Mercury Capri Fox Body applications using the factory 8.8-inch rear axle. Installation uses holes added to the frame rail along with U-bolts at the factory rear axle. The kit provides two track bar mounting positions to accommodate vehicle ride height. Detroit Speed states that the system can provide clearance for custom exhaust up to 3 inches, but available clearance depends on tire width and mini-tub width, and fuel-tank modification may be required.
