Polaris RZR S 1000 8" Portal Gear Lift

Description

Gear Down and Go Big
You can do almost anything in
your Polaris RZR S 1000. But if you want to do everything, you need an 8” GDP
Portal Gear Lift. With 8 inches of extra ground clearance and a 45% or 60%
gear reduction, nothing will stop you. Take on the mud, rocks, trails,
mountains, creeks, and dunes that nobody else can get through.

GDP—the Most Trusted Name in Portals
More riders roll
on GDP portals than any other portal system. That’s because we know how to
make them right with high quality parts and a superior design. With thousands
of rider hours put on them every weekend, you can bet they’re built to take on
any terrain.

Perfect for Mud
What makes
GDP so great for mud? The deeper you go, the more torque you’ll feel. That 45%
gear reduction paired with 8 inches of extra ground clearance means you can go
deeper and plow through more with massive tires. Or you can go even bigger and
ride even harder with our 60% gear reduction that can turn the biggest tires
like they’re stock.

A Gear Reduction That Protects Your
Drivetrain
Portals put the gear reduction at the hub instead
of in the transmission. That means your axles, differential, prop shaft, and
transmission are stressed less than stock so you can ride more.

more about how tire size and gear reduction can unleash your machine’s
potential.

Unmatched Gear Material
Our
top-of-the-line gears are made from precision-ground 9310 alloy steel so they
mate perfectly each and every time. These premium, smooth-meshing gears give
you quiet portals that won’t break.

Stronger Housings by
Design
You can’t get better housings than GDP housings because
nobody has the expertise that SuperATV has. We are the brains behind GDP after
all. We know how to engineer and manufacture them to be as strong as possible.
Choose from cast aluminum or USA-made billet aluminum housings. Either way,
you get the best boxes around.

• Our housings are reinforced in all the
  right places
• They’re built with better oil flow and gearing forces in
  mind
• There are no gimmicks and no vents because vents do more harm
  than good—we know because we tested them

The
Strongest Portal Backing Plates You Can Get
We make our
backing plates the strongest by using 5/16” thick advanced steel plating. This
steel alloy is stronger than chromoly so you can count on them lasting for
thousands of miles without bending or breaking.

Advanced
Gaskets and Seals
Whether you go with cast or billet, both
housings use:

• Advanced gaskets with excellent oil resistance and a
  lower deterioration rate than Kevlar gaskets
• Rubber O-rings that
  completely seal the housings
• A sealed input gear and double-lipped
  output seal
• 100% sealing coverage throughout so you can forget about
  oil leaks

Bearings That Rock
A bad
bearing can mean your weekend is cut short with a busted portal. That’s why we
use a double-angular contact bearing for our output shaft. It’s designed to
handle huge forces from jumps, rocks, and whatever else you run into without
failing or wearing prematurely. Every inch of GDP is built to last.

Universal Hubs and Slotted Rotors
Our precision-
ground, stainless steel slotted rotors stay cool to give you the braking power
you need when you need it. They come with 4/156, 4/137, 4/115, and 4/110 bolt
patterns and lugs. That makes your life easier because you can use wheels from
just about any side-by-side. We invented the tapered output shaft that our
hubs attach to, which provides a more secure lock that won’t wobble or wear
over time.

Reinforce Your UTV with a Frame
Stiffener
Your RZR S 1000 is built tough, but 8” GDP Portals
take things to another level. That’s why we we highly recommend using a frame
stiffener with your 8” portals. Trust us, we know from experience. Get a frame
stiffener to save your frame and forget your worries.

Patent # 11,299,042 <!– SuperATV’s GDP 8” Portal Gear Lift for the Polaris
RZR S 1000 is geared down so you can go big. It gives you a lift and a 45%
gear reduction in one box. Get the clearance to run bigger tires and the
torque you need to turn them. The lift and gear reduction are in the hub, so
they maintain suspension geometry and reduce drivetrain stress. With huge
clearance, huge torque, and optional billet aluminum housings, you can install
monster tires to take your torqued-out machine through anything.

Perfect for Mud
With 8” portals and a 45% gear
reduction, you get clearance for huge tires and a massive boost in torque.
It’ll turn monster tires like they’re stock. Your S 1000 will be the most
powerful mud flinging machine in the park. Now the challenge is finding bounty
hole tough enough for you.

Perfect for Rocks

Get tons of torque to crawl over any rock or boulder you can find by
installing an 8” portal box with a 45% gear reduction. With that much power,
there’s no boulder too big or crawl too technical. With 8” of clearance, you
can run monster tires and clear the biggest boulders easily.

potential.

Better Gears
Our gears
are precision ground and made with 9310 billet steel alloy. They’re designed
to take all the torque and abuse you can give them without chipping teeth or
blowing up. Our precise design and manufacturing mean they’re cool and quiet
even when you’re hammering down the throttle in the mud hole.

Micro Polished Gears
If you want maximum performance,
choose our precision ground Micro Polished Gears. Micro Polishing is a process
that gently smooths out any imperfections in the surface of the metal during a
two-stage, non-abrasive, burnishing process that produces a chrome-like
finish. The result is unbelievably smooth gears that have almost zero friction
or resistance. This means better oil retention and a longer lifetime than
other gears. They will stay cool and quiet, while giving you a little more
power to the ground.

Billet Housings
Choose billet or cast aluminum housings to finish your portals. Our billet
housings are CNC machined right here in Madison, Indiana and give you
increased strength and consistency over cast. Plus, they look good painted
with mud.

Reinforce Your UTV with a Frame
Stiffener
We highly recommend running a SuperATV Frame Stiffener
with your 8″ Portal Gear Lift. The stock frame just doesn’t have what it
takes. Bump too hard and the OEM frame will bend. Trust us — we’ve done it. A
frame stiffener reinforces your frame enough to let you ride your 8″ portals
with monster tires and no worries.
