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.

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

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!

Duty Ball Joints

SuperATV’s standard replacement ball joints
give you OEM quality without the OEM price! They’re made with hardened

than stock.
