FOX Quick Switch Electric (QSE) Front Sway Bar Link Disconnect – Polaris RZR Pro R
The FOX Quick Switch Electric (QSE) Front Sway Bar Link Disconnect for Polaris RZR Pro R is a bolt-on suspension upgrade that allows drivers to connect or disconnect the front sway bar instantly from inside the cab. With the push of a switch, you can adapt your suspension setup on the fly—improving articulation in technical terrain while maintaining stability for high-speed driving.
The QSE system delivers a new level of control by allowing you to quickly disconnect the sway bar when tackling rocks, ruts, or uneven trails, then reconnect it for improved handling and stability when terrain smooths out. This helps reduce head toss, improve traction, and enhance overall ride comfort.
FOX’s digressive damping characteristics keep the vehicle stable even when the sway bar is disconnected, while the rugged aluminum construction ensures durability in harsh off-road environments.
⚠️ Important Note:
This front QSE kit does not include a power harness. A rear QSE kit must be purchased to obtain the wiring harness and dash switch required for operation.
