Head-Turning Strength
Turn heads with SuperATV’s Polaris
RZR Pro R Sidewinder A-Arms. They’re absolutely massive, super tough, and
totally eye-catching with their boxed design. These A-arms aren’t just for
show though—they give you a full 1.5” of extra ground clearance and 1.5”
forward offset. You get room for 38” tires without a lift kit! Strength and
style have never been better together.

Bold A-arms

If we only had one word to describe Sidewinder A-arms, it’d be “bold.”
The tapered rectangular design looks aggressive and is super tough thanks to
improved welds and gussets. If you want hardcore strength and style, SuperATV
has you covered.

38” Tires With a 1.5” Offset
These A-arms give you room for 38” tires without a lift thanks to a 1.5”
forward offset. You also get an additional 1.5” of clearance without adding a
lift. Whether you love to tear up the mud or fly over the dunes, these A-arms
can put up with more mistreatment than OEM could ever dream of.

1/8” Alloy Steel—TIG Welded!
Sidewinder boxed A-arms are
built to be abused. We use 1/8” advanced alloy steel plating and each A-arm is
welded by hand. They’re powder coated from head to toe to resist fading and
corrosion. We lab and field test every A-arm design we’ve ever made, so we’re
confident you’ll get superior performance compared to your Pro R’s stock

We’re so confident in our Sidewinder A-arms that we back
them up with a lifetime warranty!

Beefy 7/8” Heims

We use beefy 7/8” heims on the upper joints. Why? To give you full
control over your camber. You’ll need to tweak your camber if you add goliath
tires or a lift. Sand racers, mud boggers, and rock crawlers all love heim
joints for their industry-leading adjustability and strength. If you want more
from your Pro R, you can’t beat Sidewinder A-arms.

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

Ball Joints Pair Perfectly with Heims

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 ideal for bigger machines, bigger tires,
and bigger rides—the perfect complement to your upper heims. And since they’re
greaseable and serviceable, you can keep them running perfectly.
