The AST 5100 Series Coilovers for the Honda Civic EJ9 (95-00) are high-performance suspension components designed to enhance handling and ride quality. Featuring non-inverted monotube shock absorbers, these coilovers utilize advanced technology to deliver superior damping performance compared to traditional twin-tube designs. The monotube construction separates gas pressure with a floating piston, effectively preventing cavitation and aeration within the oil chamber. The shocks include rebound adjustment via a single knob, allowing for customizable damping settings to suit various driving conditions. The adjustable platform provides precise ride height control, making these coilovers suitable for street and track applications. Built with durable materials, they are engineered for consistent performance and longevity under demanding conditions.

Designed for 1995-2000 Honda Civic EJ9 models, these coilovers are a direct bolt-on upgrade for improved handling and stability. They are compatible with stock or lowered suspensions and are ideal for enthusiasts seeking enhanced performance on the street or track. Installation involves replacing the factory shocks and springs with these coilovers, providing a straightforward upgrade process. The kit includes the shock absorbers and necessary mounting hardware. Suitable for daily driving, spirited street use, or track days, the AST 5100 Series Coilovers offer adjustable damping and ride height to optimize your Civic’s handling characteristics.

Overview

The 5100 Series shock absorbers for the 1995-2000 Honda Civic 1.4 (EJ9) utilize non-inverted / high performance monotube technology. In the past, these were known as the 4100 series. Monotube design shocks absorbers give 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 5100 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.

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.
