Strength and Style
You don’t follow the crowd. Why should your UTV? Get Polaris RZR Turbo S Sidewinder A-Arms and leave the crowd behind. Our high clearance A-arms give you a full 1.5” of ground clearance over stock. That means trails that stop other machines in their tracks won’t phase your RZR Turbo. These A-arms have a 1.5” forward offset. So you’re able to clear up to 38” tires—no lift kit required. Think of Sidewinder A-arms as your ticket to monster tires.

Does the Job & Looks Good Doing It
When you’re good at something, you tend to look good doing it. Case-in-point: Sidewinder A-arms. Sure, there are good parts out there, but when was the last time that part stole the show from the machine itself? These control arms feature a tapered design that will never be mistaken for stock. They’re as at home competing in the Mint 400 as they are on a SEMA build. Sidewinder A-arms have looks that let the crowd know that stock ain’t your thing.

The Forward Offset Advantage
The bend design means that obstacles that tore your friends' side-by-sides apart won’t even touch these high clearance A-arms. The 1.5” offset delivers improved stability, especially when taking on on steep hills. A longer wheelbase helps your ride stay smooth even as the trail gets rougher. Plus, you’ll have room for bigger tires—talk about a win-win.

Boxed A-Arms=Tougher A-Arms
If you want tough A-arms, you want boxed A-arms. They are built to take on tough conditions and not let you down. We use a UV-resistant powder coating to keep them looking good even after 10,000 miles of hard riding. SuperATV doesn’t just make a great A-arm and call it a day. We put them to the test, in the lab and the field, so you know you’re getting the best.

The best control arms deserve the best warranty. That’s why we back them for a lifetime.

Adjustable Pivot Blocks
These RZR Turbo A-arms are equipped with adjustable pivot blocks. You’ll be able to fine-tune your camber and get it how you need it. When your camber is set correctly, it prevents premature tire wear. And if you plan on making big mods—stuff like lift kits or bigger tires— adjustability is crucial to your Turbo S performing right. And if your ride is still stock, we’ve got you covered. We preadjusted these A-arms for stock specs to get you out of the garage and on the path to adventure sooner.
