Honda Pioneer 520 Portals Let You Ride the Way You Want
GDP Portals give you tons of choice. Choose a 45% gear reduction for maximum torque for big tires—perfect for mud and rocks. Choose a 30% gear reduction for a smaller torque but a higher top speed—great for trail riding while still being perfectly capable of taking on tougher terrain.

GDP Portals Save Your Drivetrain
These Honda Pioneer 520 portals put the gear reduction in the hub, so your whole drivetrain benefits. That means your axles, differential, prop shaft, and transmission avoid extra wear thanks to GDP. Portals also keep your stock suspension geometry so you don’t overextend your axles.

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
