DSE Front Speed Kit 2 - Non-Adjustable Shocks (031375DS) - 1964-1966 Ford Mustang
Transform the stance, handling, and front-end performance of your early Mustang with the Detroit Speed Front Speed Kit 2. Designed specifically for 1964-1966 Ford Mustang applications, part number 031375DS combines control arms, Detroit Tuned coilovers, a tubular sway bar, forged-steel spindles, and shock tower closeouts into an integrated performance suspension package. The system lowers ride height from 1.5 to 3 inches while relocating the coilover spring and shock to the lower control arm for improved ride control, giving your classic Mustang a more aggressive stance backed by modern suspension engineering.
The 031375DS package uses Detroit Tuned non-adjustable coilover shocks paired with 350 pounds per inch springs, providing application-specific damping without requiring you to manually tune shock settings. One-piece lower control arms incorporate cross-axis bushings and heavy-duty adjustable strut rod pivots, while the upper control arms feature Detroit Speed Caster Tuner slugs for improved alignment adjustability. Speed Kit 2 also adds a 1.25-inch OD x 0.188-inch wall tubular sway bar and forged-steel spindles using larger bearings and tie rod ends based on the design developed for Trans-Am Boss 302 Mustangs. Shock tower closeouts and relocated upper shock mounts improve clearance for wider front wheel and tire combinations while helping create a cleaner engine compartment.
