DSE QuadraLink Rear Suspension Kit - Remote-Reservoir Double-Adjustable Shocks (041731-RDS) - 1964 - 1970 Ford Mustang
Give your 1964-1970 Ford Mustang the rear suspension control and adjustability of a serious modern performance build with the Detroit Speed QUADRALink Rear Suspension Kit. DSE 041731-RDS replaces the original leaf spring suspension with Detroit Speed's performance-focused 4-link geometry and pairs it with remote-reservoir double-adjustable coilovers for extensive chassis tuning. Patented Swivel-Link technology allows the suspension to articulate smoothly without binding, while tuned high-durometer rubber bushings provide controlled, quiet movement without relying on heim joints or urethane bushings.
The 041731-RDS takes the Mustang QUADRALink package to its highest level of shock adjustability with DSE/JRi aluminum-body double-adjustable remote-reservoir coilovers featuring Detroit Tuned valving. The remote-canister design incorporates a gas-charged bladder to provide high-frequency and low-speed damping control, while billet aluminum mounts secure the remote canisters to the vehicle. Long upper links provide excellent pinion and U-joint angle control, and the adjustable Panhard rod precisely locates the rear axle laterally during hard cornering while allowing roll-center adjustment for different ride heights. The system also includes 175 pounds per inch coilover springs, a rear sway bar, an upper floor pan crossmember assembly for added chassis rigidity, and weld-on axle brackets for 3-inch axle tubes.

FAQs
What makes the shocks in DSE 041731-RDS different from standard double-adjustable shocks?
The DSE/JRi shocks combine double-adjustable tuning with remote canisters containing gas-charged bladders for high-frequency and low-speed damping control. Billet aluminum mounts are included to secure the remote canisters to the Mustang.
Does DSE 041731-RDS require a narrowed fuel tank?
Yes. Detroit Speed specifies that a narrowed fuel tank is required with the Mustang QUADRALink system and offers multiple tank configurations for different fuel system requirements.
What axle tubes are required for DSE 041731-RDS?
The included weld-on axle brackets require 3-inch axle tubes. For a complete rear-end assembly already configured with the appropriate QUADRALink mounting provisions, Detroit Speed recommends ordering the corresponding kit without axle brackets.
