A-Arms That Are Built for Battle
If you’re still running
stock arms, you don’t know what you’re missing out on. Stock arms bang on
every low-lying obstacle and the weak construction can buckle if you push them
too hard. Upgrade to SuperATV’s Polaris RZR Trail S 900 2″ Forward Offset
Boxed A-Arms to get smoother, more reliable rides. The 2” forward offset
boosts stability and gives you room to fit up to 30” tires. Combine that with
the high-clearance bends and you can cruise right over obstacles and take
massive hits without breaking.

Room to Fit up to 30”

These boxed control arms are designed to get over stuff
thanks to the 2” forward offset and high-clearance bend design. You get room
for up 30” tires without a lift and 1.5” of extra ground clearance. That makes
it harder to get hung up on branches and rocks and makes the whole ride feel

Boxed Strength for Hard Rides
boxed design maximizes strength from end to end. We make it with TIG-welded
1/8” heavy-duty steel plating and beefy internal gussets. They’re finished
with a UV-resistant powder coating to protect from corrosion. Altogether,
they’re super strong and have the bold, burly look to match. Plus, they come
with UHMW bushings preinstalled for years of smooth riding.

And if
you somehow manage to break them, we’ve got you covered with a lifetime

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

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

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.
