SPORTLINE 1 (4100 SERIES)

• Monotube design shocks absorbers gives your car a better performance than the standard twin tube design, the gas pressure is separated by a floating piston and eliminates cavitation and airation within the oil chamber.
• The 4100 series shocks allow rebound adjustment with one knob.
• The adjust platform allows the user 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 and are finished with a KTL coating for an extremely hardwearing finish.

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.

Technical specifications:

• Floating piston design with high pressure nitrogen eliminates cavitation around the piston.
• 22mm / 14mm diameter shaft struts, non-inverted.
• Steel cylinder body shocks, non-inverted.
