What is Hyper-Flex polyurethane?

Hyper-Flex is Energy Suspension's proprietary performance polyurethane material. It's formulated to be more durable and resistant to wear and tear from undercar chemicals and environmental factors than standard rubber bushings.

What's the difference between rubber and polyurethane bushings?

Rubber bushings can degrade over time from exposure to heat, chemicals, and UV rays, leading to a loss of suspension performance. Polyurethane is much more resistant to these elements, offering a longer lifespan and more consistent support for your suspension components.

Does this kit include all the bushings for the suspension?

This is a master bushing set that includes front and rear control arm bushings and front and rear sway bar frame bushings. It's a comprehensive kit for significantly refreshing your Civic Si's suspension.

About this part

Product Details

When you're looking to refresh the suspension on your 2002-2005 Honda Civic Si, this master bushing set from Energy Suspension is a solid option. It includes a full set of Hyper-Flex polyurethane bushings designed to replace the original rubber components throughout your front and rear suspension. This means you're getting new bushings for your control arms and sway bars, both front and rear, all in one package. Polyurethane is known for its ability to hold up better than rubber against common undercar fluids like oil and coolant, as well as environmental factors like UV rays and pollution.

Upgrading to these polyurethane bushings can make a notable difference in how your Civic handles. They help maintain proper caster and camber alignment, which is crucial for consistent tire contact with the road. You can expect improved control during acceleration, braking, and cornering, leading to a more stable and predictable feel behind the wheel. Because they don't break down as easily as rubber, these bushings are a long-lasting performance improvement for your car.

This kit comes in black and is proudly made in America. Replacing old, worn-out rubber bushings with fresh, well-built polyurethane can bring back a lot of the crispness and responsiveness your Civic Si had when it was new.
