DSE Front Speed Kit 2 - Single Adjustable Shocks (031378-SDS) - 1967-1970 Ford Mustang
Transform your 1967-1970 Mustang with the stance, handling, and tunable suspension control of the Detroit Speed Front Speed Kit 2. Part number 031378-SDS combines Detroit Tuned single-adjustable coilovers, performance control arms, a tubular front sway bar, forged-steel spindles, and shock tower closeouts into an integrated front suspension system. With a 1.5 to 3-inch lowering range and components engineered to complement one another, this package delivers the foundation for a sharper, more responsive performance street, restomod, or Pro Touring Mustang.
The 031378-SDS package uses Detroit Tuned single-adjustable coilover shocks paired with 325 pounds per inch springs, allowing you to dial in preferred shock settings to suit your driving style and suspension setup. One-piece lower control arms incorporate cross-axis bushings and heavy-duty adjustable strut rod pivots, while the upper control arms feature DSE Caster Tuner slugs for improved alignment adjustability. A 1.25-inch OD x 0.188-inch wall tubular sway bar adds roll control, while the included forged-steel spindles use larger bearings and tie rod ends based on the design first developed for Trans-Am Boss 302 Mustangs. Relocated upper shock mounts and shock tower closeouts also help clean up the engine compartment while creating additional clearance for wider front wheel and tire combinations.
