DSE Front Speed Kit 2 - Double Adjustable Shocks (031385DS) - 1979-1989 Ford Mustang / 1979-1986 Mercury Capri
Take your Fox Body front suspension to the next level with the Detroit Speed Front Speed Kit 2. Designed for 1979-1989 Ford Mustang and 1979-1986 Mercury Capri applications, part number 031385DS combines QA1 double-adjustable struts, tubular lower control arms, an adjustable-rate front sway bar, billet caster/camber plates, Weight Jack ride height adjustment, and forged-aluminum 2-inch drop Hubpack uprights into a comprehensive bolt-on performance package. The system is engineered to improve steering response, cornering stability, suspension geometry, and tuning capability for serious street, autocross, and track-focused builds.
The 031385DS package uses 700 pounds per inch front springs with QA1 double-adjustable struts, giving you greater control over suspension tuning than a single-adjustable setup. Detroit Speed's billet caster/camber plates incorporate Speed-LIGN technology for precise, repeatable alignment settings, while the Weight Jack system provides convenient ride height and spring adjustment. Forged-aluminum 2-inch drop Hubpack uprights improve stance and incorporate optimized Ackermann and bump-steer geometry for more predictable steering response. The Hubpack bearing system eliminates traditional spindle pin flex while reducing maintenance, and S550 Mustang brake mounting compatibility opens the door to multiple OE and aftermarket brake configurations.
