FOX Quick Switch Electric (QSE) Rear Sway Bar Link Disconnect – Polaris RZR Pro R
The FOX Quick Switch Electric (QSE) Rear Sway Bar Link Disconnect for Polaris RZR Pro R is a bolt-on suspension upgrade that allows drivers to connect or disconnect the rear sway bar instantly from inside the cab. With the flip of a switch, you can adapt your suspension to changing terrain—improving articulation on technical trails while maintaining stability for high-speed driving.
The QSE system includes rear sway bar links, a plug-and-play wiring harness, and an LED backlit dash switch, giving you full control of your suspension system without leaving the driver's seat. Disconnect the sway bar in less than one second to increase suspension travel and traction when navigating rocks, ruts, and uneven terrain. When reconnected, the system restores sway bar performance for improved handling and stability.
Even when disconnected, FOX’s digressive damping technology helps maintain vehicle stability and reduces body movement and head toss during aggressive off-road driving.
⚠️ Important Fitment Note:
The Rear Pro R QSE Links only work with factory (stock) springs. Using longer aftermarket springs may cause damage to both the sway bar links and springs.
