Tougher Boxed A-Arms
Your stock A-arms are built for stock rides. They’re perfect if you only want to ride on flat, easy trails and never let the pedal hit the floor. That’s not why you ride though. You need our Polaris RZR Trail S 1000 2" Forward Offset Boxed A-Arms if you want to take on tougher trails and have more fun. The offset makes it easy to fit up to 30” tires and boosts overall stability. Plus, they have the ground clearance and strength you need to cruise over obstacles and take a beating without buckling.

A 2” Offset for 30” Tires
When you need to get over a log or a rock, running bigger, 30” tires makes it easy. The 2” offset gives you plenty of room for bigger tires without a lift. And the 1.5” of extra ground clearance these boxed controls arms give you let you cruise over bigger obstacles. They make rough trails feel smooth and keep rolling forward without getting hung up.

Boxed for Extreme Strength
Our boxed design gives you the strength you need for unpredictable rides. Even with extra clearance, A-arm impacts happen. But thanks to their TIG-welded 1/8” heavy-duty steel plating and internal gusset system, these A-arms can handle just about anything. Their big, burly design gives them an aggressive look that’s undeniably cool. Plus, they come with UHMW bushings preinstalled for years of smooth riding.

They’re as tough as they come, but don’t worry if you manage to break them somehow—we back them with a lifetime warranty.

Adjustable Pivot Blocks
When you load up your RZR with the weight of a bunch of gear or upgrades, you can screw up your camber and ruin your ride quality. That’s why our A-arms are built with adjustable pivot blocks set to stock specs. You don’t have to touch them if you don’t need to, but they make it easy to fix your camber for a perfect ride.

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.
