DSE QuadraLink Rear Suspension Kit - Single-Adjustable Shocks (041731-SDS) - 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-SDS combines Detroit Speed's performance-focused 4-link geometry with single-adjustable DSE/JRi coilovers for improved handling, rear axle control, ride quality, and suspension tunability. Detroit Speed's patented Swivel-Link technology allows the suspension to articulate smoothly without binding while using tuned high-durometer rubber bushings instead of heim joints or urethane bushings.
The 041731-SDS configuration features DSE/JRi aluminum-body single-adjustable coilover shocks with Detroit Tuned valving plus an installed rebound adjustment knob, giving you an easy way to fine-tune shock response while maintaining excellent street ride quality. 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 allows roll-center control as ride height changes. The upper floor pan crossmember assembly significantly stiffens the rear body and frame section, and the included rear sway bar adds another level of chassis control. With 175 pounds per inch coilover springs and weld-on axle brackets for 3-inch axle tubes, this QUADRALink package gives a classic Mustang a comprehensive rear suspension upgrade for serious street and performance use.
