Big, Beefy Boxed A-Arms
When you hit the trail, the trail hits back. And if you’re using stock A-arms, that means getting hung up on obstacles and getting some ride-ending damage if you push too hard. Upgrade to something bigger and better—our Polaris RZR S 900 2" Forward Offset Boxed A-Arms give you more ground clearance and unbeatable strength. The offset gives you room for 30” too, so you can go big without a lift.
A 2” Offset for 30” Tires
The 2” offset boosts your stability and gives you room for 30” tires. Combined with the 1.5” high-clearance design on these boxed control arms, you can cruise through rough terrain without getting hung up or slowed down.
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 heavy accessories, you need to adjust your camber to avoid premature tire wear. Our adjustable pivot blocks make it easy to get perfect camber, but you don’t have to adjust them at all if your machine is still stock.
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.
