The Boxed Strength You Need
Whether you’re cruising
through rocky desert terrain or bogging through peanut butter mud, your A-arms
take a beating. That’s why you need to get rid of stock and upgrade to
SuperATV’s Polaris RZR 4 900 2″ Forward Offset Boxed A-Arms. The offset gives
you room for 30” tires without a lift. Plus, they have the ground clearance
and strength you need to cruise over obstacles and take a beating without

Room for up to 30” Tires
When you
need to get over a log or a rock nothing beats bigger tires. The 2” offset
gives you room for 30” tires without a lift. Plus the 1.5” of extra ground
clearance these boxed controls arms give you makes it even easier to get over
the crap on the trail. They make rough trails feel smooth and keep you rolling
forward without getting hung up.

Boxed Arms Are

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.

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

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.
