Upgrade Your Honda Pioneer 520 with Huge 8” Portals
Your Pioneer could use a boost—literally. SuperATV’s 8” Portals for the Honda Pioneer 520 take your machine from a minor player to a major problem. A problem for the terrain, that is. These muscular portals give you a gigantic 8-inch lift and a gear reduction all in one. Trails, creeks, mud—wherever you ride, GDP Portals for SuperATV can help you dominate.

• Gives you an 8” lift and a gear reduction in one package
• 45% or 60% gear reduction
• Maintains OEM suspension angles
• REQUIRES aftermarket suspension to clear 22” wheels and matching tires

45% or 60% Gear Reduction
A 45% or 60% gear reduction transforms your Pioneer’s torque. It gives you back the power that your gigantic tires could steal. If you’re taking on tricky trails or deep mud, you’ll love the power your portals deliver.

GDP Portals Save Your Drivetrain
GDP Portals put the gear reduction directly in the hub. This protects your entire drivetrain from unnecessary stress. Your axles, diff, prop shaft, and transmission will be protected instead of torn to bits.

Honda Portals That Are Built Tough
GDP Portals are built to be the toughest. They use 5/16” advanced steel alloy backing plates and precision-engineered aluminum housings so you can ride the way you want.

• 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
