What Riders Are Saying
This frame stiffener made a huge difference in how my RZR handles. I can feel so much more stability when hitting trails hard, especially with the bigger tires I installed. It was a straightforward install and well worth the investment for the added confidence.
— Mark S., Colorado
If you're planning on adding portals or a lift, do yourself a favor and get this frame stiffener. It beefs up the RZR's stock frame considerably, preventing unwanted flex when you're really pushing the machine. SuperATV quality is top-notch as usual.
