Powerflex is a truly engineered product, not just a copy of the stock part in a different material. Redesigned to address common factory failure parts, Powerflex bushings allow the articulation required to maintain control of movement for increased performance while far outlasting the stock parts they are replacing. 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 metallic race parts. Powerflex polyurethane engine/drivetrain mounts and reinforcements are available for some fitments to reduce movement for better throttle response and more power to the wheels.

Bushings are produced in one of three durometers – Yellow (70A, approximately 25% stiffer than stock), Purple (80A, approximately 30% stiffer than stock), and Black (95A, approximately 80% stiffer than stock). Unlike other brands using only one urethane grade for all applications, Powerflex design engineers choose the correct hardness to allow for the specific movement or rigidity required for each location while minimizing unwanted NVH.
