Rath moved his radiator from the front
to the rear of his RZR XP 900. When it
was mounted up front, mud would clog
the holes and the motor would start to
overheat. Daryl Rath drove to his first podium GNCC race in a UTV. He took advantage of his
big motor on the start and down the straights to stay ahead of a pack of Can-Am
mounted to the inside of each trailing
arm, had to be remounted on the outside of each arm.
The radius rods were also
equipped with stronger chromoly rod
ends, and the weak stock CV axle
shafts were tossed out for beefier,
The Fox rear shocks had the same
shortening modifications made as the
fronts did. The dual-speed compression and rebound adjusters were
installed back there as well. DWT
Sector rear wheels found a new
home on the narrow rear end, offering 11 inches of wheel travel.
Rath’s narrow conversion kit is
available to all Polaris RZR XP 900
owners—if you have the money. This
kit runs for $4395. Depending on your
one. The back of the cage was
extended over the rear of the chassis,
and a large rear bumper was integrated into the back of the cage. Rath
also welded two crossbars into the
top of the roll cage and bolted on a
lightweight plastic roof.
Twisted Stitch provided Rath with
cushioned seats, and Simpson five-point harnesses were installed for
safety. Individual Polaris windshields
deflect debris over the driver and
tire choice, the overall width will be
between 57. 5 and 59 inches. Rath
achieved a 58-inch width by using
25x8x12-front and 25x10x12-rear
Maxxis 4 Speed treads with TireBalls.
Fox charges just under a grand to
make the shock modifications to all
four corners without dual-speed compression and rebound adjustments.
It’s $600 more to add the adjusters.
A Rath-designed, beefed-up and
modified roll cage replaced the stock
lock into place using a cool billet-alu-
minum handle. Rath used full-nylon
nets to deflect tree branches from
entering the cockpit. These nets bolt
to the upper section of the door and
connect on the roll cage using a pin
and a similar billet handle.
The stock radiator position is not
great for nonstop muddy conditions
like at the GNCC events. The radiator
was moved to the rear of the cockpit
using integrated mounts on the roll
cage. Honeycomb was zip-tied on the
front of the radiator as well.
The flip side of the RZR XP 900 was
beefed up using Rath’s belly skids,
and Rath’s huge front bumper could
knock anything out of the way. All of

BRAD HOWE DESCRIBES WHAT
IT’S LIKE TO BE A PASSENGER
WITH DARYL RATH
Rath’s mechanic had fired up the
Baldwin-modified RZR XP 900, and
the DASA exhaust system provided
Rath’s ride with a built-in alarm
clock. The explosive sound let me
know it was time to suit up.
Daryl’s wife Jennifer graciously let
me borrow her Simpson fire suit.
Luckily, I was able to squeeze into it,
because the GNCC will not let a UTV
driver or passenger race without one.
A neck brace is not required, but
Jennifer wouldn’t let Daryl or myself
race without one under our Fly hel-
mets either. I happily obliged, and
along with the beefed-up roll cage
and five-point harness, I was feeling
much more comfortable about the
row, and we were in the fifth row back.
The green flag dropped, and we
exploded onto the first corner. This
RZR XP is as fast as it sounds, and it
got us the holeshot we needed. Two
corners later, we were in the woods,
and Daryl had to lay off the throttle.
Driving smooth is key to staying out of
trouble and finishing the race.
Rath’s RZR XP was stable around
off-cambered corners, and 10 inches
of ground clearance was good in the
mud. There were a few deep sections
that ate up many competitors. We
powered through them, though, without a problem
The Fox shocks were dialed in perfectly for the rough Aonia Pass
course. The Twisted seats conformed
comfortably to my back, and the
Simpson five-point harness
remained tight the entire race. It felt
like I was a passenger in a Cadillac.
Although, there was that one 70-mph
square edge that almost cost me my
lunch. Even during that scary
moment, Daryl was completely in
control. He even looked over to
chuckle at my girly screams, without
skipping a beat.
Being a passenger in a UTV race
is not on everyone’s to-do list, and if
I didn’t draw that short stick back at
the office, it wouldn’t have been on
mine either. But, Daryl Rath made it
worthwhile. He drove methodically,
picking the best lines and staying
out of the deep mud. Thanks to the
excess power, we were able to make
many passes on the straights. The
RZR XP has some of the best UTV
brakes on the market. We would
slow quickly, from 80-mph top
speeds, to brake-slide into 90-
After 50 minutes, we took the
checkered flag for third place, and I
was able to embarrass myself on my
first GNCC podium. I didn’t get to
drive, but even as a passenger, that
was the most fun I’ve had in a UTV.
Rath’s RZR XP has some of the best
aftermarket doors we have tested.
They open and close smoothly and
UTV racing has exploded the last
couple of years, and the turnout at this
event was no different. The starting
line was full of race machines and
spectators. There were five UTVs per
