DSE Front Speed Kit 2 - Non-Adjustable Shocks (031378DS) - 1967-1970 Ford Mustang
Give your 1967-1970 Mustang the stance, handling, and front-end control of a modern performance build with the Detroit Speed Front Speed Kit 2. Part number 031378DS combines control arms, Detroit Tuned non-adjustable coilovers, a tubular sway bar, forged-steel spindles, and shock tower closeouts into an integrated front suspension package. With a 1.5 to 3-inch lowering range and components engineered to work together, this kit delivers a comprehensive suspension upgrade for performance street, restomod, and Pro Touring Mustangs.
The 031378DS package uses Detroit Tuned non-adjustable coilover shocks paired with 325 pounds per inch springs, providing application-specific damping without requiring manual shock adjustments. 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. Relocating the upper shock mounts beneath the fender aprons and adding shock tower closeouts also creates a cleaner engine compartment and additional clearance for wider front wheel and tire packages.
