Give your 1979-1993 Fox Body Mustang modern handling, braking, and steering performance with Detroit Speed's Lowering Front Hubpack Uprights. These uprights replace your existing knuckles with forged aluminum pieces for improved strength, optimized suspension geometry, a 2" drop in front ride height, and unlocked compatibility with S550 braking systems.
Superior Design: The forged aluminum design provides unmatched strength at a reduced weight compared to the factory steel, ensuring refined and reliable steering control. These uprights also utilize stronger SN95 ball joints for durability, and are pre-configured with optimal bumper steer geometry for consistent steering performance. The built-in 2" drop gives your Fox Body a more aggressive, lowered stance for improved looks and a lower center of gravity for more controlled maneuvers. DSE designed these uprights with modern hubpack bearings to eliminate spindle pin flex, improving durability and reducing maintenance. Finally, these uprights are made to be compatible with S550 braking systems for increased stopping power.
