Maximize Performance with GDP Portals
Take your Honda Rubicon beyond its limits with SuperATV’s 6” Portal Gear Lift. It gives you a lift and gear reduction in one package. And with your choice of a 30% or 45% gear reduction, you get the torque you need to conquer mud, rocks, and hills. You’ll also get more ground clearance and the ability to run bigger tires. If you want to dominate every ride, GDP Portals give you the power and performance to do it all.
Unmatched Torque and Power
A 30% or 45% gear reduction gives your Rubicon serious power. If you want to tackle deep mud, haul heavy loads, or run massive tires, go with the 45% reduction. If you want to maintain your top speed while boosting torque, the 30% reduction is your best bet.
Protect Your Drivetrain for the Long Haul
Extra power means extra strain—but these Honda Rubicon GDP Portals protect your drivetrain. The gear reduction is built into the hub, keeping your axles, differential, and transmission protected from excess wear. And since SuperATV's Honda Rubicon portals maintain your stock suspension, your axles stay cooler and last longer.
