Polaris RZR S 900 2" Forward Offset Boxed A-Arms

Stock A-arms on your Polaris RZR S 900 won't cut it if you're serious about trail riding. They hang up on rocks and obstacles, limit your tire options, and leave you vulnerable to damage on rough terrain. These boxed A-arms are built to handle real abuse—they give you the clearance you need for 30-inch tires and the strength to keep running hard, year after year.

This is a complete A-arm kit made from 1/8-inch steel with internal gussets welded throughout for extra rigidity. The 2-inch forward offset and 1.5-inch ground clearance design work together so you can fit bigger tires and still navigate obstacles without bottoming out. They arrive with UHMW bushings already installed, and you choose your ball joint style at checkout—or go with just the arms and reuse your stock ball joints.

The steel is UV-resistant powder coated to fight corrosion, and these arms come with a lifetime warranty. The adjustable pivot blocks let you dial in your camber if you add a lift kit or load up with accessories, though you can skip that step if your machine stays stock. Everything's designed so you can keep these on the trail for years without worrying about failure.

You've got four choices here, depending on how hard you push your machine.

Super Duty 300M: Made from 300M grade steel with a steel-on-steel design, these joints are 2.25 times stronger than factory. They've got an easily-accessible grease zerk so you can service them in the field.

Keller: These use a two-piece design that threads on like a bolt—no snap ring to worry about. Chromoly stud and tool-steel body keep them locked in place. They're rebuildable and greaseable, so you can maintain them for the long haul.

Heavy Duty: Built from hardened 4340 VAR steel with zinc plating, these handle twice the load of OEM joints. They come with accessible grease zerks and adjustable geometry.

Standard Duty: Chromoly steel studs and housings with zinc plating give you factory strength at a lower price point.
