Maximize Performance with GDP Portals
Take your Honda Foreman’s performance over the top with SuperATV’s 6” Portal Gear Lift. You get a choice of a 30% or 45% gear reduction to boost torque. Plus, you’ll get more ground clearance and the ability to run larger tires. For the ultimate lift, you need SuperATV's portals.
Get the Torque You Need
Get ultimate torque and acceleration with a choice between a 30% or 45% gear reduction. For maximum torque and larger tires, you’ll want to go with a 45% reduction. You’ll have the power to take off from a dead stop, haul large loads, and trudge through muddy and rocky terrain. Choose 30% to maintain top speed while still getting that boost in torque.
Keep Your Drivetrain Protected
With that extra weight being thrown 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, SuperATV's Honda Foreman portal gear lift keeps your factory suspension so you have cooler-running axles.
The Toughest Portals on the Market
When you’re dominating the trails with your buddies, the last thing you need is a portal getting damaged and stopping your ride. That’s why SuperATV designed its cast and 6061 billet aluminum housings. They’re perfect for rough terrain and hard rides. They’re backed by SuperATV's advanced steel backing plates that give them unmatched strength.
The 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—SuperATV knows because it tested them
Advanced Gaskets, Seals, and Bearings
The 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
