Polaris RZR 4 900 1.5in. Forward Offset A-Arms

Your stock A-arms aren't built for serious riding. They'll flex, wear out, and limit what your RZR 4 900 can do. These 1.5" forward offset A-arms from SuperATV give you the strength and clearance to push harder on rough terrain, rocky climbs, mud, and whatever else you throw at them.

What You're Getting

Two complete A-arms with adjustable pivot blocks already set to factory specs. You'll also get a set of self-lubricating UHMW bushings—they're maintenance-free and only get smoother the more you ride. Ball joints are sold separately, but you can add them at checkout and have them installed free of charge (otherwise you'll reuse your existing stock joints).

Built Strong, Built to Last

These arms start with 1.25" tubing—that's a quarter bigger than what came on your machine. SuperATV uses heavy-duty steel and covers it with a powder coat that stops rust and keeps things looking fresh for years. The whole assembly backs up that durability with a lifetime warranty.

More Ground Clearance, Room for Bigger Tires

You get 2" of extra clearance from the arched design. The 1.5" forward offset opens up space so you can run 30" tires without hassle. Adjust the pivot blocks if you want to dial in your camber—or leave them as-is if stock feels right.

Ball Joint Options
