SuperATV Sidewinder A-Arms for Polaris RZR Pro R

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. Strength and style have never been better together.

Bold A-arms

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.

1/8 Alloy Steel - TIG Welded!

Sidewinder boxed A-arms are built to be abused. They're powder coated from head to toe to resist fading and corrosion.

Beefy 7/8 Heims

Why? To give you full control over your camber. You'll need to tweak your camber if you add goliath tires or a lift. If you want more from your Pro R, you can't beat Sidewinder A-arms.

Preassembly Available

If you want to hit the trails as soon as possible, ordering SuperATV A-arms with preinstalled ball joints is the way to go. This saves you money and gives you more time in your Polaris RZR Pro R.

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

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

SuperATV 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.
