How do the 3-way adjustments work?

The 3-way adjustment lets you control rebound (how the shock extends), low-speed compression (how it handles gradual bumps), and high-speed compression (how it handles sharp impacts) separately. This allows for very specific tuning of your Mustang's suspension response.

What is the benefit of the inverted strut design?

An inverted strut design moves the larger diameter piston and oil to the bottom of the strut. This setup is stronger and better able to handle the heavy side loads and braking forces that occur during aggressive driving and track use.

Do these coilovers include everything needed for installation?

This kit includes the monotube coilovers with external reservoirs, and camber-adjustable front top mounts and solid rear top mounts. Refer to the manufacturer's installation instructions for any additional hardware or tools that may be required.

About this part

Product Details

Already running a track-focused setup? The AST 5300 Series Coilovers are the next piece to fine-tune your 2015-2020 Ford Mustang's suspension. These are 3-way adjustable motorsport coilovers designed for serious track use, allowing you to dial in rebound, low-speed compression, and high-speed compression independently. The inverted strut design handles heavy side loads and braking forces common on the track.

Each damper uses a monotube design for consistent performance. You get external reservoirs for the adjustment controls, giving you flexibility to fine-tune your suspension's response. This kit also includes camber-adjustable front top mounts and solid rear top mounts to further alter front-end geometry for improved grip.
