Head-Turning Strength
Turn heads with SuperATV’s Polaris RZR Pro R Sidewinder A-Arms. They’re absolutely massive, super tough, and totally eye-catching with their boxed design. These A-arms aren’t just for show though—they give you a full 1.5” of extra ground clearance and 1.5” forward offset. You get room for 38” tires without a lift kit! Strength and style have never been better together.

Bold A-arms
If we only had one word to describe Sidewinder A-arms, it’d be “bold.” The tapered rectangular design looks aggressive and is super tough thanks to improved welds and gussets. If you want hardcore strength and style, SuperATV has you covered.

38” Tires With a 1.5” Offset
These A-arms give you room for 38” tires without a lift thanks to a 1.5” forward offset. You also get an additional 1.5” of clearance without adding a lift. Whether you love to tear up the mud or fly over the dunes, these A-arms can put up with more mistreatment than OEM could ever dream of.

1/8” Alloy Steel—TIG Welded!
Sidewinder boxed A-arms are built to be abused. We use 1/8” advanced alloy steel plating and each A-arm is welded by hand. They’re powder coated from head to toe to resist fading and corrosion. We lab and field test every A-arm design we’ve ever made, so we’re confident you’ll get superior performance compared to your Pro R’s stock A-arms.

We’re so confident in our Sidewinder A-arms that we back them up with a lifetime warranty!

Beefy 7/8” Heims
We use beefy 7/8” heims on the upper joints. Why? To give you full control over your camber. You’ll need to tweak your camber if you add goliath tires or a lift. Sand racers, mud boggers, and rock crawlers all love heim joints for their industry-leading adjustability and strength. If you want more from your Pro R, you can’t beat Sidewinder A-arms.

Let SuperATV Do the Work—Get Lower Ball Joints Preinstalled!
Want to spend more time on the trails and less time in the garage? Purchase a pair of SuperATV lower ball joints with your A-arms, and we’ll install them for free! We save you money and time so you can get back to doing what you love.

NOTE: You must re-use your stock ball joints if you don’t select a preinstalled ball joint at checkout.

Keller Ball Joints Pair Perfectly with Heims
Keller Ball Joints use a two-piece design that eliminates the need for a snap ring. They thread onto your A-arms like a nut and bolt, which makes these ball joints virtually impossible to pull out. The high-quality chromoly steel stud combined with an advanced tool-steel body makes them ideal for bigger machines, bigger tires, and bigger rides—the perfect complement to your upper heims. And since they’re greaseable and serviceable, you can keep them running perfectly.
