In the seller's words
The Detroit Speed QUADRALink Rear Suspension Kit is a game-changer for muscle cars and pro-touring builds. It eliminates traditional leaf springs and replaces them with a fully adjustable 4-link system, allowing for superior handling, improved traction, and precise rear axle control. Unlike conventional 4-link kits, QUADRALink features Swivel-Link technology, ensuring smooth, bind-free articulation without the noise and short lifespan of Heim joints or urethane bushings.
Ideal for street performance, auto-cross, road racing, and high-horsepower applications!
✅ Detroit Speed Swivel-Link Technology – Eliminates binding while providing full suspension articulation
✅ Double Adjustable Coilover Shocks with Remote Reservoirs – Allows fine-tuning of ride height, damping, and rebound
✅ Tuned High-Durometer Rubber Bushings – Reduces NVH (Noise, Vibration, and Harshness) while ensuring longevity
✅ Adjustable Panhard Bar (Double Adjustable) – Provides precise lateral axle location during cornering
✅ Upper & Lower Trailing Arms (Single Adjustable) – Improves stability and traction under acceleration and braking
✅ Rear Upper Shock Crossmember – Strengthens rear frame section for improved rigidity
✅ Black Powdercoated Finish – Provides corrosion resistance and long-lasting durability
Everything you need for a full 4-link rear suspension conversion!
