SuperATV 2in. Forward Offset Boxed A-Arms for Polaris RZR S 900

When you hit the trail, the trail hits back. And if you're using stock A-arms, that means getting hung up on obstacles and getting some ride-ending damage if you push too hard. Boxed Arms Are BetterThe UV-resistant powder coating protects from corrosion and they come with preinstalled UHMW bushings. With end-to-end durability, you can take them on hard rides for years. Adjustable Pivot BlocksWhen you add a lift or a bunch of heavy accessories, you need to adjust your camber to avoid premature tire wear. SuperATV adjustable pivot blocks make it easy to get perfect camber, but you don't have to adjust them at all if your machine is still stock.
