Boxed A-Arms for Serious Rides
If you’re still rolling on stock A-arms and expecting to push your RZR to its limits, you need to think twice. Upgrade to SuperATV’s Polaris RZR S 1000 2" Forward Offset Boxed A-Arms for the burly strength you need to get wild. They’re built with a 2” forward offset to extend your wheelbase and give you room for 30” tires without a lift. The 1.5” of extra ground clearance make every ride smoother and the boosted strength makes them virtually indestructible.

Fit up to 30” Tires
You can fit up to 30” tires thanks to the 2” offset. Plus with 1.5” of extra ground clearance, you can roll right over tons of obstacles that would’ve banged into your stock A-arms before. With our high-clearance control arms, rough trails feel smoother and extreme trails are easier.

Boxed Arms Are Better
What makes boxed arms the best you can get? They’re made with 1/8” steel plating and use internal gussets to boost their strength even further. The UV-resistant powder coating protects from corrosion and they come with preinstalled UHMW bushings. With end-to-end durability, you can take them on hard rides for years.

And thanks to their lifetime warranty, we’ve got you covered if you do manage to break them somehow.

Adjustable Pivot Blocks
When you add a lift or a bunch of weight to your RZR, you screw up your camber. With messed up camber comes poorer ride quality and shorter tire life. These A-arms come with adjustable pivot blocks set to factory specs so you can always have perfect camber.

Let SuperATV Do the Work—Preassembly Available!
Want to spend more time on the trails and less time in the garage? Purchase a set of SuperATV ball joints with your A-arms and we’ll install them for you 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 pre-installed ball joint at checkout.

Super Duty 300M Ball Joints
We took the strongest ball joint material on the market—300M grade steel—and combined it with our superior design engineering to make the strongest ball joint on the market. It comes with an easily-accessible grease zerk and an adjustable steel-on-steel design, making it easy to keep your ball joints maintained and flexible. At 2.25x stronger than stock, you won’t find a better ball joint.

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.

Heavy Duty Ball Joints
Our heavy-duty ball joints are designed with ultimate performance and convenience in mind. Whether you’re doing flips or chasing hills, our proprietary blend of hardened 4340 VAR steel and zinc plating means this ball joint can take it. Our heavy-duty ball joints also come with easily-accessible grease zerks and an adjustable design. Extensive lab and field testing shows that our heavy duty ball joints can withstand double the pressure of an OEM ball joint!

Standard Duty Ball Joints
SuperATV’s standard replacement ball joints give you OEM quality without the OEM price! They’re made with hardened chromoly steel studs and housings—all zinc plated—for superior strength and longevity. All of this delivers a ball joint that’s as strong as or stronger than stock.
