Maximize Your Honda Foreman’s Performance with GDP Portals
Your Honda Foreman has always been good to you. Take its performance over the top with SuperATV’s 4” Portal Gear Lift. Choose between a 15% or 30% gear reduction to boost torque. With our portals, you get more ground clearance and the ability to run larger tires. They’re the ultimate upgrade for the ultimate rider.
Get the Torque You Need
You get to customize your torque and acceleration with a choice between a 15% or 30% gear reduction. For maximum torque and larger tires, you’ll want to go with a 30% reduction. It’ll give you the power to take off from a dead stop or haul large loads. Choose 15% to maintain a high top speed while still getting that bump in torque.
Protect Your Drivetrain
When you’re throwing all that extra weight around, you can cause damage to your drivetrain. GDP Portals put the gear reduction in the hub, so your drivetrain gets protected from extra wear. Plus, our Honda Foreman portal gear lift keeps your factory suspension to give you cooler-running axles.
The Toughest Portals You Can Get
When you’re hitting the trails with your buddies, the last thing you need is to break down. That’s why our cast and 6061 billet aluminum housings are designed for rough terrain and hard rides. They’re backed by our advanced steel backing plates that give them unmatched strength.
- 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
