The stock Maxxis Bighorns that
come on the XP 1000 are super lightweight for increased performance, but
they are also very prone to flats. A
solid set of eight-ply tires from GBC,
ITP, Maxxis or any other company
will increase durability. We have had
great luck with 30-inch ITP Ultracross
R Specs and the GBC Kanati Mongrel
in the desert. For WORCS or more
MX-type terrain, a 28-inch tire will
provide better turning stability and be
quicker out of the hole.

ARP HEAVY-DUTY WHEEL STUDS
The 10mm stock wheel studs
were prone to breakage on the XP 900.
The size was carried over from ATVs
to the RZR 800 and then onto the bigger and heavier XP 900 model before
it became a weak link. As the XP 1000
got bigger and heavier, Polaris bumped
the wheel-stud size to 12mm. By
design, the new XP 1000 studs press
through the brake rotors and into the
The problem is that they have a tendency to back out or loosen, especially
with any aftermarket wheels that flex or
give a little at the mounting holes. The
stock studs only use about 3/8th of an
inch of spline, counting what is wasted
on the rotor. ARP, in partnership with
Maxwell Industries, has developed
a much stronger press-in stud that
uses more than an inch of the press-in spline. ARP has also developed a
thread-in type “Race” wheel stud that
requires tapping of the OEM hub prior
These 35-percent-larger ARP studs
are heat-treated 8740 chromoly that’s
hardened to 180,000 psi and CAD-plated for resistance to the elements.
We have used these for miles upon
miles of trouble-free desert and off-road
racing with many different brands of

FOUR- OR FIVE-POINT HARNESSES
Safety is the number one concern when off-roading, and a proper harness is
the key to keeping you locked down and safe within your cage. Pro Armor offers
both 2-inch and 3-inch harnesses in both five-point and four-point designs. The
Pro Armor harnesses feature sewn-in pads, a water-resistant cell-phone pocket
and an LED cab light.
With a newer RZR, you will have to bypass the stock seatbelt indicator by
splicing the two wires together or by purchasing a $12 bypass plug. If you don’t
complete this circuit, you will be restricted to under 20 mph.
Pro Armor offers both 2- and
3-inch harnesses in both four-point and five-point designs.

beadlock wheels, TireBalls, and 30-inch Maxxis
Coronado eight-ply tires to win the UTV King of the
Hammers. He also armed his XP1K with aftermarket wheel lugs.
