BMW Sway Bar (20mm) - H&R 71490

Product Information

A sway bar—also called an anti-roll bar or stabilizer bar—is a suspension component designed to reduce body roll during cornering. It essentially a metal rod that connects the left and right wheels (usually via short sway bar links) and twists slightly when the vehicle leans. This twisting action helps keep the car flatter in turns, improving stability and handling.

• Excessive Body Roll in Turns: The car leans more than usual when cornering, making it feel less stable.
• Clunking, Knocking, or Rattling Noises: Often heard when driving over bumps or during turns—usually from worn or broken sway bar links/bushings.
• Loose or Wandering Steering Feel: The steering may feel less precise or the car may “float” more, especially on curves.
• Uneven or Premature Tire Wear: Poor handling can lead to increased stress on certain tires.
• Reduced Cornering Grip: The car might feel like it’s losing traction sooner when turning.

About HR

In the late 1970’s Mr. Werner Heine (H) and Mr. Heinz Remmen (R) saw the need for an improved street suspension with a strong belief that vehicles could have more control and better handling. Today, every spring produced by H&R comes from the H&R ISO 9001 certified engineering and manufacturing facility in Germany. H&R Sport Springs offer the handling characteristics and aggressive appearance that you’ve been looking for, without the harsh ride characteristics of less-advanced spring systems. H&R Sport Springs feature more control and are engineered for the street, making them comfortable and fun to drive. Over the years, H&R has developed a diverse line of products and suspension applications including four different spring product lines, six different coil over product lines, two different Cup Kit product lines, a sway bar program, the largest wheel spacer and adapter program in the industry, camber adjustment bolts, a lightweight line of I.D. Race Springs, and the ever popular Quick-Safe Wheel Bolt Stud conversions. All of their products are vehicle specific and are produced to enhance handling potential, personal style, and retain vehicle ride comfort.
