GDP Portals Are Game-Changing

Get a GDP Portal Gear Lift to get power and performance that you can't find anywhere else. With a 4" Portal Gear Lift for your Honda Pioneer 1000, you have options. Choose 15% or 30% gear reductions and cast or billet aluminum housings—you can optimize for the riding you love most. If you like to break parts like it's going out of style, upgrade to dual idlers. They give you maximum strength for wild rides.

What Is a Dual Idler?

After years of research and development, GDP has created 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. Precision CNC grinding ensures perfect mating. Gears are made from the industry's toughest 9310 steel alloy.

Perfect No Matter How You Ride

GDP Portal Gear Lifts are made to conquer any terrain you face. 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're the kind of rider that can break anything.

This Gear Reduction Protects Your Drivetrain

GDP Portals have a gear reduction built into the hub. Because it's at the end of your drivetrain instead of in the transmission, the whole system benefits. Your axles, differential, prop shafts, and transmission will work less and wear less thanks to these portals.

Max Tire Size Recommendations for 4" Portal Gear Lift

Max tire sizes are measured at full compression and full turn. The given tire sizes are the largest that fit without rubbing. With minor trimming or a small amount of rub, larger tire sizes can be used.
