Honda Pioneer 1000 6" Portal Gear Lift

More Clearance. More Torque. More Pioneer.
Put your Honda Pioneer 1000 on GDP Portals and find out what it’s really capable of. SuperATV’s 6” Portal Gear Lift gives you room for monster tires and the torque to put them to work. Choose a 30%, 45%, or 60% gear reduction, cast or billet aluminum housings, and single or dual idler gears. We’ve done the hard work so you can take on the hard trails.

Which Gear Reduction Should You Choose?

• 30% gear reduction: Get extra torque while retaining more speed for faster trail rides.
• 45% gear reduction: Step up the torque to help turn bigger tires.
• 60% gear reduction: Get our deepest reduction for big tires and deep mud.

Should You Upgrade to Dual Idlers?
Adding a second idler gear is easy. Getting both gears to share the load takes precision—and that’s where GDP earns its name. Our CNC-ground 9310 steel alloy gears mesh perfectly to spread the load over twice as much surface area. You get more reliable torque transfer and our strongest gear set. If you plan to push your Pioneer hard, this is the upgrade you want.

Cast or Billet Aluminum?
Choose cast or billet aluminum housings for your Pioneer. Both options have reinforcement for gear retention and an interior optimized for oil flow. Each kit also includes 5/16” backing plates made from an advanced steel alloy that’s stronger than chromoly.

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

Before you order, check the Fitment tab for your model and year, wheel requirements, and compatibility restrictions.

Do You Need a Frame Stiffener?
We strongly recommend a SuperATV Frame Stiffener with your 6” portals. Portals and oversized tires can put extra strain on your machine, and a frame stiffener adds reinforcement where you need it.

How Do Portals Affect Your Drivetrain?
GDP Portals put the gear reduction at the wheel hubs. That helps reduce stress on your axles, differential, prop shaft, and transmission compared to oversized tires without gear reduction.
