Bushings are produced in one of three durometers – yellow (70A – stiffer than rubber), purple (80A), and black (95A – very stiff) measured hardness. Powerflex design engineers utilize the correct hardness to allow for the specific movement or rigidity required for each location while minimizing unwanted NVH (noise, vibration, harshness). Urethane hardness is standardized per fitment and location. Select parts are available in an optional stiffer urethane (The Black Series) for track and autocross performance where NVH is less important.
Powerflex polyurethane bushings are designed to decrease the amount of deflection in your car's suspension which improves handling, driver feedback, and tire wear. A premium polyurethane formulation is used, specifically to provide minimal NVH and increased longevity over stock rubber bushings
Powerflex Bushings are designed to address common factory failure parts, Powerflex bushings allow the articulation required to far outlast the stock part it is replacing while maintaining control of the movement for increased performance. Additionally, Powerflex Engineering Line products for some fitments include unique features like polyurethane monoballs and offset geometry to provide ultimate performance without the harshness of a metallic monoball race part. Polyurethane engine/drivetrain mounts and reinforcements are available for some fitments to reduce movement for better throttle response and more power to the wheels.
Powerflex bushing are sold per location to fit specific needs. An automobile's bushings and mounts wear at different rates making "complete-kit" bushing sets unnecessary for most buyers. Replacing only the weak links in your car's suspension is a great way to tighten handling without stressing the budget.
Powerflex copper-based grease is supplied with every bushing set. Powerflex suggests using only a copper based grease for lubrication. Bushings will rarely need re-lubing due to the unique grooves and knurls cast into the material to hold the lubricant. It is not suggested to use an "anti-seize" product for lubrication.
