Detroit Speed’s S10 Quadralink Rear Suspension Kit is the ultimate bolt-in solution for builders looking to replace leaf springs with a true performance 4-link. Designed for high-horsepower applications and serious handling upgrades, this system delivers superior traction, consistent ride quality, and a refined stance - all engineered with the quality, geometry, and packaging Detroit Speed is known for.
This isn’t just a 4-link—it’s a fully tuned suspension system. The Detroit Speed Quadralink is engineered with optimized geometry to deliver sharper handling and improved balance without sacrificing ride comfort. At its core are QA1 double adjustable coil-over shocks, offering 18 clicks of compression and rebound tuning, paired with Detroit Speed–spec’d 200 lb/in springs. The result is a well-balanced setup that responds confidently—whether you’re carving corners, launching hard, or cruising the street.
The Quadralink system is optimized for 5"-6" lowered ride height, and includes a bolt-in frame notch and crossmember for added suspension travel and structural rigidity. Get the aggressive stance you want without compromising function.
Detroit Speed’s Quadralink system uses parallel 4-link geometry to provide anti-squat tuning for improved launch and traction control, while an adjustable track bar delivers precise lateral control and roll center adjustability. This combination eliminates the wheel hop and axle wrap typical of leaf spring setups, giving you better grip and more predictable behavior under power. At the heart of it all are Detroit Speed’s patented Swivel Links, engineered for superior articulation and a noticeable reduction in noise, vibration, and harshness - delivering smooth, quiet performance without compromising strength.
This kit is designed to work with Detroit Speed’s optional Ford 9” housings, available in multiple configurations to support high-horsepower builds. Whether you’re upgrading now or later, this system is ready to handle the torque. Includes weld-on axle bracket kit (P/N 200173DS)
Bolt-in design with factory-location brackets means no frame fabrication is required. Minor cutting and drilling may be necessary, but no specialty tools or extensive modifications are needed. It’s the premium solution without the shop headaches.
Detroit Speed kits are proudly designed, tested, and built in Mooresville, North Carolina.
