Unlock Power and Performance with GDP Portals

SuperATV's GDP 4" Portal Gear Lift for the Honda Pioneer 500 delivers unparalleled power and performance that can't be found elsewhere. Choose between a 15% or 30% gear reduction to attain the high-torque capabilities you desire, and customize it with your preferred housing option to create the ideal portal for your needs. Opt for the unbeatable strength of our dual-idler configuration and discover how you can make work more manageable and weekends more enjoyable.

Ideal for All Types of Adventures

Opt for the 30% gear reduction and conquer muddy terrain with ease, benefiting from a substantial torque boost. Navigate rocky landscapes effortlessly, as you gain the torque necessary to surmount boulders as if they were mere pebbles. If your focus is on everyday chores and trail riding, select the 15% gear reduction for the clearance and power required to breeze through ruts and ditches while towing a trailer full of supplies. Plus, you'll retain enough speed to comfortably cruise down the road or tackle trails.

Drivetrain-Friendly Gear Reduction

Portal lifts relocate the gear reduction from the transmission to the hub, easing the workload on your drivetrain components. This translates to increased longevity for essential elements such as axles, differentials, prop shafts, and transmissions. Among the numerous advantages of a portal gear lift, reduced stress on your drivetrain ranks at the top.

Unrivaled Portal Strength

We've invested years in research and rigorous testing to bring you portals that can withstand the most demanding off-road adventures. With reinforced cast or billet aluminum housings and advanced alloy backing plates, nothing will impede your journey.

  • Our housings boast reinforced construction for gear retention and optimized oil flow.
  • Advanced steel alloy backing plates surpass chromoly in strength.
  • Elevate performance with Portal Blood, a specially formulated gear oil for GDP Portals.
  • We avoid gimmicks like vents, having discovered through testing that they do more harm than good.
