Energy Suspension Hyper-Flex PolyBush Kit for Honda Civic EP / EP3

Restore precision to your Honda Civic’s chassis with the Energy Suspension Hyper-Flex Poly Bush Kit – SKU 16.18112G.

Factory rubber suspension bushes are designed primarily for comfort and noise isolation. Over time, these bushes can soften, crack and deteriorate, allowing excessive suspension movement and reducing steering precision.

Energy Suspension’s Hyper-Flex polyurethane bushes provide a firmer and more durable alternative to conventional rubber, making them a popular upgrade for enthusiasts looking to improve the response and handling characteristics of the Honda Civic EP chassis, including performance-oriented EP3 applications.

Improved Handling & Suspension Response

By reducing unwanted movement between suspension components, polyurethane bushes can help provide:

• Sharper steering response
• Improved chassis feedback
• More consistent suspension geometry
• Reduced unwanted suspension movement
• Improved cornering stability
• Reduced wheel hop and traction loss
• Longer service life than ageing factory rubber bushes
• More direct and predictable handling

This makes the Energy Suspension kit suitable for everything from daily-driven Civic EP models to fast-road and track-focused EP3 builds.

What Does Energy Suspension 16.18112G Include?

The Hyper-Flex master kit includes bushes for several major suspension locations.

Front Control Arm Bushes

Energy Suspension reference 16.3116

Includes polyurethane bushes for the front control arm assemblies, helping reduce excessive movement under braking, acceleration and cornering.

Front Anti-Roll Bar Bushes

Energy Suspension reference 16.5133

Designed for a 1-inch / approximately 25.4 mm front anti-roll bar.

Rear Suspension / Control Arm Bushes

Energy Suspension reference 16.3118

Includes multiple bushes used throughout the rear suspension/control arm assemblies to restore and improve rear suspension response.

Rear Anti-Roll Bar Bushes

Energy Suspension reference 16.5134

Designed for a 15 mm rear anti-roll bar.

Installation Grease

Energy Suspension polyurethane grease is supplied for applicable bush installation points.

Why Upgrade to Polyurethane Bushes?

OEM rubber suspension bushes offer excellent comfort, but they are deliberately soft. Under hard acceleration, braking and cornering, rubber bushes can flex considerably.

That movement can affect:

• Wheel alignment
• Steering response
• Suspension geometry
• Traction
• Braking stability
• Cornering accuracy

Energy Suspension Hyper-Flex polyurethane is designed to provide greater resistance to deflection while maintaining sufficient compliance for suspension movement.

The result is a chassis that can feel tighter, sharper and more responsive.

Installation Note

Professional installation is recommended.

Original suspension bushes generally need to be removed from the relevant arms and suspension components before the polyurethane replacements can be fitted.

Always use the supplied polyurethane-compatible grease where instructed.

Because polyurethane is firmer than standard rubber, a small increase in noise, vibration and harshness (NVH) may be experienced. This is normal for a performance-oriented polyurethane suspension upgrade.
