TeraFlex Pneumatic Dual-Rate Sway Bar (Bronco 2021+)

The TeraFlex Bronco Pneumatic Dual-Rate Sway Bar delivers improved handling and articulation in one clean, simple system. Designed to replace either the factory hydraulic sway bar or the factory single-rate bar, this pneumatic unit provides reliable performance without the complexity of OE components.

If you’ve ever had to crawl under your Bronco and lay in the dirt to disconnect a sway bar, you already understand why a simple in-cab, push-button release matters. Trail capability shouldn’t require getting dirty before the trail even starts, and then again before hitting the road.

Using our proven dual-rate design, this sway bar delivers confident control on pavement and controlled articulation off-road. Built to fit all Bronco trims, it’s a straightforward upgrade for drivers who want durability, simplicity, and predictable performance.
