Dominate Any Trail with Honda Rubicon GDP Portals
Your Honda Rubicon is a beast, but why not make it unstoppable? SuperATV’s 4” GDP Portal Gear Lift gives you the power, clearance, and durability to conquer any terrain. You get power and performance thanks to the lift and gear reduction built into the hub. And with your choice of a 15% or 30% gear reduction, you get the perfect balance of torque and speed. With GDP Portals, you’ll be ready for anything.
Get the Power You Need
With two gear reduction options, you’re in control. A 30% reduction delivers max torque for hauling heavy loads and powering through deep mud. Stick with 15% if you want a speed-friendly setup while still getting that extra boost in torque.
Drivetrain Protection Built In
More power doesn’t have to mean more wear. GDP Portals put the gear reduction in the hub, which means your drivetrain stays protected. Plus, the suspension maintains factory geometry, so your axles run cooler. Plus, the gear reduction goes in the hub, so your axles, differential, and transmission all benefit from it and wear less.
Stronger, Smarter, Tougher
SuperATV doesn’t cut corners—its portals are built to last. Your choice of cast or 6061 billet aluminum housings, combined with Advanced steel backing plates, make them tough enough for anything the trail throws at you.
The 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—SuperATV knows because it tested them
Advanced Gaskets, Seals, and Bearings
The 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
