Gen 3 Portals are Geared for All
SuperATV’s GDP 4”
Portal Gear Lift for the Yamaha YXZ is Geared for All. Choose from 15% or 30%
gear reductions and cast or billet aluminum housings so you can optimize to
fit your needs.

Perfect for Mud
If you
move up to a 30% gear reduction, you’ll be ready to take on bigger, sloppier
mud holes. That boost in torque means you can dominate monster bounty holes
without getting stuck. The lift gives you room for bigger tires so you can
take your YXZ mud monster over-the-top. When you’re done with the mud, a 30%
gear reduction can get you through trails, roads, and rocks just as easily.

Perfect for Rocks
Put 4” portals and a
30% gear reduction on your machine and get the torque you need crawl over
rocks like they’re not even there. You’ll have the clearance to get over
anything without scratching up your skid plate, and you’ll have room to run
bigger tires. These portals are built for boulders.

Perfect for Trails
Get 4” portals and a 15% gear
reduction on your YXZ and take on the trail less traveled. You’ll cruise
through the trail and fly past those technical hills or washouts easily thanks
to that extra torque. It’ll show you what your machine is really capable of.

machine’s potential.

Better Gears
gears are precision ground and made with 9310 billet steel alloy for high
strength and high speed. That means they’re cool and quiet even when you’re
hammering down the throttle on the road, and they have strength to withstand
every ride.

Stronger Housings by Design
We dare you to find housings stronger than what we make for our GDP portals.
Just like everything else that goes into this product, our housings are well
researched and long tested. And you get a choice—go with cast or USA-made,
CNC-machined 6061 billet aluminum. Regardless of what you pick, you’re getting
portal housings with strength and reliability that is unmatched.

  • 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

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
  • A sealed input gear and double-lipped output seal
  • 100% sealing coverage throughout so you can forget about oil leaks
