Polaris RZR XP Turbo S Sidewinder A-Arms—1.5" Forward Offset

Stock A-arms limit what your RZR can do. These boxed control arms give you 1.5 inches of extra ground clearance, which means you can run tires up to 38 inches without a lift kit. The 1.5-inch forward offset keeps your machine stable on steep terrain and lets you tackle obstacles that would catch other riders off guard. If you want to fit bigger rubber and clear rougher ground, this is how you do it.

Built to Last

Boxed construction means these arms won't bend or flex when you're pushing hard. They come with a UV-resistant powder coat that holds up after thousands of miles of abuse. SuperATV backs them with a lifetime warranty because they're confident they'll take whatever you throw at them. The tapered design also looks nothing like factory parts—this is the kind of upgrade people notice.

Adjustable Camber & Smart Geometry

Built-in adjustable pivot blocks let you dial in your camber to match your setup. That keeps tire wear even and makes sure your Turbo S handles right, whether you're running stock specs or planning bigger mods like lift kits. These come preadjusted for stock geometry, so you can install them and go.

Ball Joint Options

You've got three choices here. The Super Duty 300M joints use the strongest ball joint steel available and are 2.25 times tougher than stock—they come with accessible grease zerks and an adjustable steel-on-steel design. The Heavy Duty option uses hardened 4340 VAR steel with zinc plating and can handle double the load of an OEM joint. Standard Duty joints give you chromoly construction with zinc plating and match or beat stock strength at a lower price.

If you order ball joints with your A-arms, SuperATV will install them for free. Otherwise, you'll need to reuse your existing stock joints.
