The AST 5100 Series Coilovers for the Honda Civic 1.6 Vtec EJ1 (94-95) 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. Rebound adjustment is easily accessible via a single knob, allowing for precise tuning to match driving preferences and conditions. The adjustable platform provides versatility for various setups, making these coilovers suitable for both street and track use. Built with durability and performance in mind, they offer improved stability, responsiveness, and control.

Designed to fit 1994-1995 Honda Civic models with the 1.6 Vtec engine, these coilovers are a direct replacement for the factory suspension. They are engineered for easy bolt-on installation, providing a significant upgrade over stock shocks. The kit includes the coilover assemblies with adjustable platforms and rebound control, ensuring comprehensive suspension tuning. These coilovers are ideal for enthusiasts seeking enhanced handling, lowered stance, or improved performance on the street or track. Compatibility is specific to the EJ1 chassis with the 1.6 Vtec engine, and no additional modifications are typically required for installation. They serve as a reliable upgrade for daily drivers, track days, or spirited driving.

Overview

The 5100 Series shock absorbers for the 1994-1995 Honda Civic 1.6 Vtec (EJ1) 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.
