Gear Down and Conquer the Trails

Elevate your off-road experience with the SuperATV 4” GDP Portal Gear Lift for your Honda Pioneer 520. This innovative upgrade not only provides a 4” lift but also empowers you with a 15% or 30% gear reduction, unlocking performance capabilities you never thought possible. Whether you prefer cast or billet aluminum housing and the added strength of dual idler bearings, the GDP Portal Gear Lift ensures that no trail is too challenging when you're riding on it.

What Is a Dual Idler®?

Achieving perfection requires dedication. After extensive research and development, our dual idler gear portals stand out from the rest. By incorporating a second idler gear within the portal box, we distribute the load across a larger surface area, resulting in more dependable torque transfer and the toughest gear set available. However, the precision CNC grinding process ensures that these gears work seamlessly together. Crafted from the industry's most durable 9310 steel alloy, our gears prove that dual idlers make a significant difference, thanks to GDP's commitment to quality and expertise.

Ideal for All Types of Riders

If you're a fan of off-roading, you'll be amazed by the mud-slinging capabilities of a 30% gear reduction offered by Honda Pioneer 520 portals. With larger tires and enhanced torque, you can effortlessly conquer even the thickest mud that used to slow you down. Our 30% gear reduction excels in various terrains, but if you prefer maintaining a higher top speed, the 15% option provides robust power without sacrificing your UTV's maximum velocity.

Drivetrain-Friendly Gear Reduction

Unlike traditional transmission-based gear reductions, our portal lifts relocate the gear reduction to the hub, thereby reducing the strain on your Pioneer's vital components. This results in extended durability for your axles, differential, prop shaft, and transmission, making reduced stress one of the primary benefits of a portal gear lift.
