Portals Reinvent Your Ranger
Your Polaris Ranger XP 570 is full of untapped potential. Unleash the beast with SuperATV’s GDP 4” Portal Gear Lift. Choose a 15% or 30% gear reduction to get the boosted torque you want. If you never slow down, upgrade to dual idler gears to get the strongest portals on the planet. Our portals are built on the back of unmatched dedication and experience. We weren't the first to put a portal on a Ranger—just the first to do it with a kit anybody gave a damn about. Get GDP Portals and reinvent your Ranger.

What Is a Dual Idler®?
Perfection takes time. After years of research and development, we’ve made our dual idler gear portals unlike any other. By placing a second idler gear in the portal box, the load gets spread over twice as much surface area for more reliable torque transfer and the strongest gear set you can get. Two idler gears don’t do a thing if they’re not mated perfectly, though. Precision CNC grinding ensures ours do. Our gears are made from the industry’s toughest 9310 steel alloy. Didn’t think dual idlers mattered? With GDP’s quality and experience, they finally do.

Ride Them Anywhere
Portals dominate mud, but they’re not just for mud. They destroy rock gardens, but they’re not just for rocks. Ride them anywhere you want any way you want, and you’ll have power and performance like you never thought possible. Get a 15% gear reduction for faster rides with enough torque to get wild. If you want the ultimate geared-down, torqued-up ride for monster tires, go with a 30% gear reduction. Grab dual idlers on either if you need portals that can survive the apocalypse. You know who you are.

A Gear Reduction That Protects Your Drivetrain
Portal gear lifts put the gear reduction right in the hub, meaning your drivetrain isn’t put under a bunch of unnecessary stress. This means your axles, differential, prop shaft, and transmission are safe from early wear and tear. You’ll be able to ride harder and longer, and your machine’s most vital parts will thank us.

Every Part Is Built for Strength
Strength is in the DNA of GDP Portals. Our cast and billet aluminum housings are the thickest and strongest you can get. Combine that with 5/16” backing plates made from an advanced steel alloy, and our portals are unstoppable.
  • Our housings are reinforced for gear retention and optimized for oil flow
  • Advanced steel alloy backing plates are stronger than chromoly
  • Enhance with Portal Blood—gear oil formulated for GDP Portals
  • There are no gimmicks and no vents because vents do more harm than good—we know because we tested them

Advanced Gaskets, Seals, and Bearings
Our portals use:
  • Advanced gaskets and O-rings with excellent oil resistance and low deterioration rates
  • A sealed input gear and double-lipped output seal
  • 100% sealing coverage throughout so you can forget about oil leaks
  • Double-angular contact output bearings to prevent premature wear
  • Roller idler and drive bearings to maintain perfect gear meshing

Protect Your Ranger with a Frame Stiffener
A Polaris Ranger 570 portal lift combined with big tires and another suspension lift can bend your side-by-side’s frame if you push it too hard. Beef it up with a frame stiffener to give you confidence and peace of mind when you put the pedal down.
