DSE QuadraLink Rear Suspension Kit - Non-Adjustable Shocks (041731DS) - 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 041731DS combines Detroit Speed's performance-focused 4-link geometry with DSE/JRi non-adjustable coilover shocks for improved handling, rear axle control, ride quality, and overall chassis response. 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 041731DS configuration features DSE/JRi aluminum-body non-adjustable coilover shocks with Detroit Tuned valving, giving you a performance-oriented shock package without the need to manually dial in shock settings. 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, while the included rear sway bar further supports balanced handling. With 175 pounds per inch coilover springs, weld-on axle brackets for 3-inch axle tubes, and a design that accommodates a 3-inch exhaust, this QUADRALink package gives a classic Mustang a comprehensive rear suspension foundation for serious street and performance use.

Fitment Notes
DSE 041731DS is designed for 1964-1970 Ford Mustang applications. The included weld-on axle brackets require 3-inch axle tubes. If you plan to order a complete rear-end assembly, Detroit Speed recommends ordering the corresponding QUADRALink kit without axle brackets. A narrowed fuel tank is required with the QUADRALink system. Detroit Speed lists 080123DS for fuel-injected applications, 080188DS for applications requiring a Holley fuel pump, 080122DS for carbureted applications, and 080151DS for the 1000 Series fuel pump. The system is also designed to work with Detroit Speed Mustang Mini-Tubs.
FAQs
Are the shocks included with DSE 041731DS adjustable?
No. The 041731DS kit uses DSE/JRi aluminum-body non-adjustable coilover shocks with Detroit Tuned valving. This provides performance-focused shock response without requiring external damping adjustments.
Does DSE 041731DS require a narrowed fuel tank?
Yes. Detroit Speed specifies that a narrowed fuel tank is required with the QUADRALink system and lists several tank configurations based on the Mustang's fuel system.
What axle tubes are required for DSE 041731DS?
The included weld-on axle brackets require 3-inch axle tubes. If your build uses a complete rear-end assembly with the required QUADRALink brackets already installed, Detroit Speed recommends ordering the corresponding kit without axle brackets.
