Details & Inspection Notes
This QUADRALink kit (041712-RDS) is the double-adjustable version, pairing Detroit Speed's Swivel-Link 4-link system with double-adjustable monotube shocks and remote reservoirs rather than the single-adjustable coil-overs used on other QUADRALink kits.
What's included
- Double-adjustable monotube shocks with remote reservoirs
- 250 lbs./in. coilover springs, black finish
- Single-adjustable upper and lower trailing arms, with mount braces
- Double-adjustable panhard bar
- High-durometer rubber bushings, black, finished in black powder coat
Fitment
Built for pro-touring and muscle car rear ends; axle brackets are sold separately, and installing them can call for welding, unlike the bolt-on-only approach used on some other QUADRALink kits. Rotors, calipers, and mounting hardware aren't included either, so factor all of those into the budget alongside the axle brackets themselves before the build gets underway.
Does installing this require welding? Axle bracket installation can require welding; the kit components themselves bolt on.
What's the spring rate? 250 lbs./in.

Suspension Setup & Installation Checklist
- Inspect top mounts, damper seals, bushings, and ball joints prior to fitment.
- Set initial spring preload, collar heights, and damper rebound clicks symmetrically left to right.
- Torque all suspension control arm pivot bolts while the vehicle is at resting ride height (loaded suspension).
- Perform a complete 4-wheel laser alignment once ride height has settled to ensure optimal handling and tire wear.
