Polaris RZR XP Turbo Radius Arms

Your RZR XP Turbo's rear suspension geometry matters when you're pushing hard through rough terrain. Stock radius arms can bind up and fight against your suspension's natural movement, especially once you start adding bigger tires or a lift. These radius arms swap in to let your machine move the way it's supposed to — without fighting itself.

How They Work

The key difference is the pivot point. Instead of a fixed connection like a typical heim joint, these arms use a design that lets the inner mount move both vertically and horizontally. That means when your suspension cycles through bumps and dips, the arm flexes with the motion instead of resisting it. You keep full control of your geometry adjustments too — want to run a lift kit, taller trailing arms, or oversized rubber? You can do that without losing ride quality.

Built Tough

They're made from extra-strength steel — the same thermo-mechanically rolled material used in truck frames and heavy equipment. That's roughly 4 times the strength of what Polaris put on your machine from the factory. SuperATV backs them with a lifetime warranty, so you know they're built to actually take a beating on the trail.

What You Get

• Rear radius arm kit (2016–2021 RZR XP Turbo or RZR XP 4 Turbo)
• High-strength steel construction
• Full vertical and horizontal articulation at inner pivot
• Lifetime warranty

Important Notes

Fitment: These fit 2016–2021 Polaris RZR XP Turbo and RZR XP 4 Turbo only. They will not fit vehicles running a Polaris rear bumper. If you're running one, you'll need to remove it first.

Color note: Voodoo Blue and Velocity Blue finishes are different from Sky Blue — make sure you're picking the right color for your build.
