What is the main benefit of using polyurethane sway bar bushings?

Polyurethane bushings, like these from Energy Suspension, are more rigid than stock rubber ones. This allows your sway bar to control body roll more effectively, leading to improved handling and a more connected feel to the road.

How do these bushings improve handling?

By providing a firmer mounting point for the sway bar, these bushings reduce flex and allow the sway bar to do its job more efficiently. This results in less body lean during cornering and a more stable feel, especially when driving enthusiastically.

Are these bushings difficult to install?

Energy Suspension notes that their sway bar bushings are popular for their easy installation. Typically, this involves removing the old rubber bushings and installing the new polyurethane ones in their place, often with basic hand tools.
