If you're building a custom drag car or heavily modifying a rear-wheel-drive vehicle for serious straight-line performance, getting the rear suspension dialed in is crucial. This QA1 Heavy Duty Pro Rear Drag 4-Link System is designed to give you a solid foundation for that performance, helping to control axle wrap and improve launch consistency. It's a well-built system that streamlines the fabrication process for a dedicated drag setup.

This kit includes everything you need to build a performance drag race style 4-link suspension. You'll get the necessary brackets, trailing arms, and a diagonal link kit to properly locate the rear axle. It also comes with tube adapters, QA1 rod ends for smooth articulation, QA1 coilovers with 150lb springs for adjustable ride height and stiffness, and a shock crossmember. The heavy-duty design means it's built to handle the stresses of hard launches, and the wide range of tunability allows you to fine-tune your suspension's response for different track conditions. Plus, it's made in the USA and includes all the necessary hardware, making your custom fabrication process more straightforward.

When setting up a 4-link system, proper alignment and geometry are key to achieving optimal performance and handling. This kit provides the components to achieve that, but always refer to QA1's installation instructions for detailed guidance on setup and adjustment to get the most out of your drag suspension.
