AST 5300 Series 3-Way Motorsport Suspension

AST Suspension 5300 Series 3-Way is a high-performance adjustable damper system developed for demanding Motorsport and Track applications, where precise control over chassis behavior and suspension response is essential.

The 5300 Series features 3-way damping adjustment, providing independent control of Rebound, Low-Speed Compression and High-Speed Compression. This allows drivers and race engineers to fine-tune the suspension response according to vehicle setup, tire characteristics, circuit conditions and driving style.

The separate low- and high-speed compression adjustments provide greater control over how the damper responds to different suspension velocities. This allows the chassis to be configured for both vehicle movements such as braking, acceleration and cornering, as well as faster suspension inputs caused by curbs, bumps and changes in track surface.

Rebound adjustment further allows the extension behavior of the damper to be controlled, helping optimize chassis balance and weight transfer throughout a lap.

With its broad damping adjustment range, the AST 5300 Series 3-Way is intended for serious performance applications where suspension setup plays an important role in maximizing vehicle and tire performance.

AST develops its suspension systems around vehicle-specific configurations, with damper valving, spring specifications and mounting hardware selected according to the intended application. Exact configuration and adjustment ranges vary by vehicle and AST Part Number.

The system is particularly suited to track cars, race cars and high-performance applications where detailed damper tuning and repeatable chassis behavior are required.

Professional motorsport installation and setup are recommended, including ride-height configuration, corner weighting, wheel alignment and damper tuning.
