Gen 3 Portals Are Geared for All
We know better than to
assume that all riders want the same thing. So we kept that in mind when
designing our Gen 3 GDP Portals. When you get a 4” Portal Gear Lift for your
Kawasaki Teryx S, you get to be part of the design process. Do you want a 15%
or 30% gear reduction? And how about those housings—will it be cast or billet
aluminum? Whatever you choose, you’re getting a badass set of portals that’s
custom fit for your ride style.

GDP—The Most Trusted Name in

You may have noticed that more riders come to SuperATV
than anyone else for portal gear lifts. There’s a reason for that: people want
the best for their machine. We’ve invested more time and money than anyone
else all in the name of manufacturing the best portal gear lift on the market.
Thanks to our industry-leading technology and countless hours of field and lab
testing, we’ve succeeded. GDP Portals are proof.

Perfect for

Portals and mud are a match made in heaven. Everyone knows
you can’t truly enjoy mud pits if you’re not rolling on GDP. The extra 4” of
lift keep you from getting swamped in deep bogs and also give you room for
bigger tires. And don’t even get us started on the torque boost! Our gear
reduction—either 15% or 30%—will have you cutting through muck like it’s

A Gear Reduction That Protects Your

Our portals place the gear reduction directly in the
hub, as opposed to in the drivetrain. This greatly reduces the amount of
stress placed on your side-by-side’s most important parts. Your portals won’t
have your axles, prop shaft, and transmission working overtime, meaning your
driveshaft will last longer. That saves you time and money in the long run.

Top-Notch Gear Material
You can’t
have a solid portal gear lift without the best dang gears on the market.
That’s why we use top-of-the-line 9310 alloy steel gears. They’re precision
ground for perfect mating and quiet operation, and they’ll keep your portals
running flawlessly. Don’t hold back behind the wheel—our premium gears will
deliver a smooth ride no matter what.

Stronger Housing by

The portal housings are arguably one of the most
important components of a portal gear lift. After all, they’re what keeps
everything safe and protected. So we spared no expense in designing the
strongest and most reliable housings imaginable. After years of testing and
research, we’re able to present you with two unbeatable options: rock-solid
cast or USA-made billet aluminum with a CNC-machined finish. Either way, if it
says GDP, you know you’re getting the best portal box on the market.

  • 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

Unbeatable Portal Backing Plates
Like every other part of GDP Portals, our backing plates shatter the standard.
They’re made with an advanced steel alloy that’s specialized for use in
hardcore, high-force applications. At 5/16” thick, our backing plates are even
stronger than chromoly steel. You can trust they won’t fail, no matter how
much abuse you put them through.

Advanced Gaskets and

Whether you go with cast or billet, both housings use:

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

Nothing But the Best

Every piece of our Teryx S 4” portals is built for
battle, right down to the bearings. Our premium bearings are designed to keep
your portal gear lift running smoothly in all conditions. The incredibly
strong roller bearing holds the idler gear in place, absorbing all of the
internal pressure in the process. We also use a double-angular contact bearing
for the output—we knew it had to be strong because it takes the brunt of the
force while you’re riding. Overall, our portal bearings will keep you rolling
for miles without fail.

Universal Hubs and Slotted

All of our portals utilize precision-ground, stainless
steel slotted rotors. We designed them to stay cool and deliver braking power
right when you need it. To make your life even easier, we include universal
hubs that have 4/156, 4/137, 4/115, and 4/110 bolt patterns and lugs—that
means you can run pretty much any UTV wheel under the sun. We also invented
the tapered output shaft that our hubs attach to. It gives you a safe, secure
lock that won’t wobble over time.
