The front E39 540i/M5 sway bar link connects the sway bar (anti roll bar) to the rest of the suspension. This link is for the front sway bar (left or right) but sold individually. As the suspension and the sway bar go through their motions the link rotates and twists. Stock links suffer from high-friction materials and a small surface area that wears quickly. On lowered cars the ball joints are often out of position, or at an extreme articulation, which puts greater strain on the ball joint and causes faster wear. If you hear clunking from the front suspension, especially over bumps and potholes, the sway bar links should be evaluated.
This is an OEM swaybar link manufactured by TRW - the original supplier to BMW for this part, as well as many other bushings and mounts. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
Links are sold individually and we recommend replacing them only in pairs.
