The rest of the Sparks Racing test RZR was outfitted with a cage and doors from
TMW, 3-inch Fox Shox, Sand Tires Unlimited paddles and a Cognito sway bar link.
The twin-can aluminum, stainless steel exhaust system mounts cleanly in place of
the bulky stocker. It sounds racy and helps the engine flow better. It’s not annoyingly loud.

That part alone is $35.
Sparks’ test RZR had a few more
items installed on it to finish it off. Some
are items they sell in-house, others are
not. The list of parts you can get direct
through Sparks Racing includes a complete Fox Shox package. These are
3-inch-bodied shocks with stock travel
numbers but include more oil, bigger shafts and rebound adjustments.
Of course, high- and low-speed compression as well as preload adjustments can be made. The set of four
shocks sells for $3995. This suspension
setup was developed with the help
of Cognito Motorsports. The company also supplied adjustable sway bar
links that not only secure the stock
sway bar better than the stock fasteners, they make it slightly adjustable.
The pair of links cost $189.
Out on the corners, the four wheels
built by Method are also available
at Sparks. They cost $193 each and
come with a 4+ 4 or 5+ 5 offset. Wrapped
around the Method wheels for our day
in the dunes were four lightweight
Sand Tires Unlimited Sand Blasters.
For now, the only UTV Sparks is developing and selling products for is the
Polaris RZR line. The rest of the car was
outfitted with a TMW cage, doors and
roof. The stock plastic was covered by
a custom wrap from Finish Line Signs
right in Bakersfield, California.
When we turned the key and started
the modified RZR, we were pleasantly
surprised the machine was not overly
loud. The twin Sparks mufflers do a
good job sending a racy tone rocketing
out the back instead of spewing an
annoying scream. In fact, we think it’s
much quieter than a single uncorked
muffler on a sport quad engine. The
sound does feel fast and sporty, building revs quickly and dropping off just
as fast when you chop the throttle
pedal. For comparison, a stock XP 1000
feels a little lazy when cruising around
the dunes. Its 1500 pounds in soft sand
is not exactly tail-happy. Driving the
Sparks RZR was different. The motor
was peppy, squirting the machine forward with every tap of the throttle. It felt
more like driving on tacky dirt than in
Drop the pedal to the metal (or the
plastic pedal to the plastic floorboard)
and the Sparks RZR came to life. It was
peppy and strong, putting you back
into the bolstered stock seat. There is
zero lag, and the engine feels crisp and
