How do I adjust the ride height and rebound on these coilovers?

You can adjust the ride height by changing the spring perch location on the shock body. The rebound damping is adjusted using the knob on top of the damper, with 12 distinct positions to choose from.

Do I need to buy new top mounts for these coilovers?

No, these AST 5100 Series coilovers are designed to work with your Mustang's original factory top mounts. This simplifies installation.

What does it mean that these dampers are rebuildable?

If the dampers experience an issue or wear out over time, they can be sent to a certified AST service center for repair. This means you can service them rather than needing to replace the entire unit.

About this part

Product Details

These coilovers use a monotube design. That means a larger piston inside the damper helps control the rebound adjustments more precisely. Because it's a monotube, there's no air mixed in with the oil, so the valving stays responsive. You get 12 distinct positions for rebound adjustment, letting you feel the difference with each click. Plus, these dampers are rebuildable at a certified AST service center if any issues come up down the road.
