DSE QuadraLink Rear Suspension Kit - Double-Adjustable Shocks (041731-DDS) - 1964 - 1970 Ford Mustang
Transform the rear suspension of your 1964-1970 Ford Mustang with the Detroit Speed QUADRALink Rear Suspension Kit. Designed to replace the original leaf spring suspension, DSE 041731-DDS combines Detroit Speed's performance-focused 4-link geometry with double-adjustable coilover shocks for a major step forward in handling, axle control, ride quality, and suspension tuning. The patented Swivel-Link design allows the suspension to articulate smoothly without binding while using tuned high-durometer rubber bushings instead of rod ends or urethane bushings.
Long upper links provide excellent pinion and U-joint angle control, while the adjustable Panhard rod precisely locates the rear axle laterally during hard cornering and provides roll-center adjustment for different ride heights. The upper floor pan crossmember assembly adds valuable strength and rigidity to the rear body and frame section. DSE/JRi aluminum-body coilovers feature Detroit Tuned valving, and the double-adjustable shocks provide two independent adjustments with a broad tuning range to match the suspension to the driver and performance demands while retaining excellent street ride quality. The package also includes 175 pounds per inch coilover springs, a rear sway bar, and weld-on axle brackets for 3-inch axle tubes.
