Polyurethane rear sway bar bushings for the 2002-2006 7th Gen Honda Civic replace the loose and spongy stock rubber bushings. The urethane bushings hold up better than rubber, which become more pliable over time. This causes the sway bar to lose its effectiveness. Urethane bushings will help restore precision and rigidity to the swaybar mounts and make the anti-roll bar perform better. Price includes the pair of rear sway bar bushings and a lifetime warranty.
Unlike other urethane bushings using only one or two urethane grades, Powerflex design engineers choose the correct hardness to allow for the specific movement or rigidity required for each component while minimizing unwanted NVH. Bushings are typically produced in one of three grades – Yellow (70-80A, approximately 25% stiffer than stock), Purple (80-90A, approximately 30% stiffer than stock), and Black (90-95A, approximately 80% stiffer than stock).

Polyurethane has been available as a specialized plastic for over thirty years. However, recent advances have made it possible to engineer very special properties into this exciting material.
Suspension bushings are one of the most highly stressed components fitted to a motor car. They undergo enormous strains in the most arduous of conditions with no maintenance or lubrication.
The material standard bushings are manufactured from is a rubber compound containing natural products which deteriorate with age. It becomes softer and more pliable, resisting the forces placed on it less and less. Therefore allowing more and more movement of suspension components and offering less and less control over the suspension geometry.
This causes excessive tire wear, braking instability and poor handling. This is the single biggest reason you can instantly tell the difference driving a three year old car and a new one. However even new cars will benefit from Powerflex bushings! Because of their superior design they offer much more effective control of the suspension components to a much greater extent than normal rubber items.
Old and soft rubber bushings cause incorrect geometry and excessive tire wear as well as braking instability
With the technological advances in this material it has been possible to overcome the common problem associated with harder bushings, which is increased noise. By correctly engineering the polyurethane compound, bushings can be made 25-30% stiffer than new rubber items but with exactly the same noise absorbing properties.
