Overview

The 5100 Series shock absorbers for the 2006-2012 Porsche 911 3.8 Turbo 4WD (997) utilize inverted / upside down technology. The inverted design is race proven technology and produces an extremely strong damper, providing better suspension geometry under heavy lateral and braking loads as seen in a road and track environment.

The 5100 Series shock absorbers give your car a better performance than the standard twin tube design. With the 5100 Series suspension you can adjust rebound with one knob. The adjust platform allows you to adjust the ride height of your car. AST suspension shock bodies are specially designed to keep maximum stroke, even with a lower ride height.

How a Monotube design works?

Monotube design is essential for performance. The oil and nitrogen are separated by a floating piston, and allows the use of a larger piston, increasing the damper performance and sensitivity felt by the driver, all this added together produces more grip, gives more control and driver feedback from your vehicle.

What is a rebound adjustment?

Rebound controls the rate of extension of your shock absorber. By changing the rebound you can directly change the characteristics of the vehicle.
