The ECS Engineered Performance Polyurethane Differential Bushing with Black anodized 6061-T6 aluminum Sleeve Sets take care of driveline slop and reduce power deflection while increasing throttle response and overall drivetrain rigidity.

After your engine produces power, and before your wheels propel your vehicle forward, energy is lost through your drivetrain. These losses are measurable and significant and are made worse by worn or failing bushings.

ECS recognized the need for more performance-oriented differential bushings, and have arrived at another world-class product.
