Gear Down and Go Big
You didn’t get a Ranger just to haul fence posts around your property, you got a Ranger because you wanted to have the ultimate party wagon. With an 8” GDP Portal Gear Lift installed, you’ll tear up mud holes, destroy rock gardens, and definitely start a party everywhere you go. All that ground clearance gives you room for up to 34” tires, and you can upgrade with extreme strength with dual idler gears. With your choice of a 45%, 60%, or 70% gear reduction, you’ll have torque to be a mud monster.
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.
Mud Can’t Stop a 45%, 60%, or 70% Gear Reduction
You know what 8 inches of lift can do. It gives you room for huge tires and lets you cruise over the mud instead of plowing through it. What really makes GDP rock is the 45%, 60%, and 70% gear reduction options. That gives you a whole lot of torque and a whole lot of power to the ground. It gives you punchy acceleration that makes turning those big mud tires easy. Mud and portals are a match made in heaven.
A Gear Reduction Protects Your Drivetrain
Portals put the gear reduction in the hub which means your drivetrain benefits from the gear reduction just as much as the rest of your machine does. Your axles, differential, prop shafts, and transmission are under less stress with portals installed. That means less wear and more riding.

Housings and Backing Plates Built Stronger
GDP Portals are the strongest you can get because we know how to make them tough. We’ve been using them and refining them for years. Whether you go with cast or USA-made, 6061 billet aluminum housings (which look awesome), you’ll get unmatched strength through superior design. Combine that with 5/16” backing plates made with an advanced steel alloy, and you’ve got the brawniest portals on the market.
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
- A Frame Stiffener Is Required
An 8” portal kit is a heavy-duty piece of hardware for heavy-duty machines, and as awesome as the Ranger XP 1000 is, it’s not quite up to snuff. That’s why a frame stiffener is required. Trust us—we’ve hit enough bumps to know that bending a stock frame can happen. Don’t do it. Get a frame stiffener.
