Polaris RZR Pro R Turbo R Sidewinder A-Arms

Ultra-Strong Polaris RZR Pro R  Turbo R Sidewinder A-Arms 
Make a bold statement with SuperATV’s Polaris RZR Turbo R Sidewinder A-Arms. With their aggressive boxed design, they’re built to stand out and built to last. These heavy-duty A-arms don’t just look tough—they deliver an extra 1.5” of ground clearance for better performance on rough terrain. It’s the perfect blend of rugged strength and head-turning style.

Head-Turning Design
If we had to pick one word for our Sidewinder A-Arms, it’d be bold. With a tapered rectangular design, they’ve got that aggressive look that stands out—and they’re built just as tough. The reinforced welds and gussets add serious strength, so you’re getting more than just style. If you’re after rugged performance with a head-turning edge, look no further.

1/8” Alloy Steel—TIG Welded!
Sidewinder boxed A-arms are made to take a beating. Built with 1/8” advanced alloy steel plating and hand-welded for next-level strength, they’re ready for anything you throw at them. The powder coat finish protects against rust and fading, keeping them looking sharp. Like all our A-arms, they’re lab and field tested to outperform your Turbo R’s stock setup—because we don’t just claim toughness, we prove it.

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

Strong 7/8” Heims
We run strong 7/8” heims on the upper joints and standard ball joints on the lowers. It gives you full camber adjustability, which comes in handy if you’re throwing on massive tires or adding a lift. Heims are perfect for sand, mud, and rock riders because they’re tough and adjustable. If you want to get more out of your Turbo R, Sidewinder A-arms are the upgrade you’ve been looking for.

Preassembly Available
We want you back on the trails as soon as possible. That’s why we give you the option to order our Sidewinder A-Arms with preinstalled ball joints. Don’t worry—we do it for free. This saves you time and money, so you’ll be back in your Turbo R in no time.

NOTE: You must reuse your stock ball joints if you don’t select a pre-installed ball joint at checkout.

Keller Ball Joints
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 perfect for bigger machines, bigger tires, and bigger rides. And since they’re greaseable and rebuildable, you can keep them running perfectly.

Super Duty 300M Ball Joints
We took 300M steel—the strongest stuff out there—and built ball joints that are super tough. They’re 2.25x stronger than stock and designed to handle whatever you throw at them. With an easy to reach grease zerk and an adjustable steel on steel setup, keeping it maintained is a breeze. If you want durability without the hassle, this is it.

Heavy Duty Ball Joints
Our Heavy Duty Ball Joints are made for riders who push limits. Engineered from hardened 4340 VAR steel and finished with zinc plating, they’re built to last. With easy to reach grease zerks and an adjustable design, maintenance is simple. They've been tested to take on 2x the pressure of OEM joints—so you can ride harder, longer, and with confidence.
