Powerflex Upgraded Polyurethane Suspension Bushings for BMW E90 / E91 / E92 / E93 Non-M RWD 3-Series Models.
Over time, OEM rubber bushings wear from constant movement, heat, and exposure to road debris. This wear and tear can lead to increased play in the suspension components, affecting handling performance and ride quality. Symptoms of worn bushings include increased body roll during cornering, excessive vibration and noise over bumps, and less precise steering feel.
Powerflex bushings not only boast a Lifetime Warranty, but they are also made from polyurethane, which has improved performance and durability qualities over OEM rubber. Over time, polyurethane is less susceptible to the wear and tear of rubber bushings and is resistant to abrasion, tearing, and degradation from oil, grease, and other chemicals encountered on the road.
Benefits of upgraded bushings include:
Increased Tire Life
Decreased deflection
Improved responsiveness
Reduced Braking Distances
Improved Performance
Increased Safety

Please confirm anti-roll bar diameter before ordering any anti-roll bar bushings
