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.

Introducing the Dual Idler®

Perfection is a journey, not a destination. After years of meticulous research and development, our dual-idler gear portals stand out as unique and innovative. By incorporating a second idler gear within the portal box, the load is distributed over twice as much surface area, ensuring a more reliable torque transfer and the most robust gear set available. However, having two idler gears is meaningless without perfect mating, and that's precisely what our precision CNC grinding accomplishes. Our gears are crafted from the industry's toughest 9310 steel alloy. If you ever doubted the significance of dual idlers, GDP's quality and expertise will make you reconsider.

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.
