Elevate your Can-Am Defender's performance with SuperATV’s GDP 4” Portal Gear Lift. While GDP may not have been the first to introduce a side-by-side portal kit, they made the first one that truly mattered. With the option of a 15% or 30% gear reduction and the addition of a unique, dual idler gear, this kit is unmatched in strength. Experience the game-changing power and discover why GDP has become the most respected name in the portal game.
What is a Dual Idler®?
Experience the epitome of perfection with our unique dual idler gear portals. They have been intricately designed and meticulously developed over years of research. By innovatively implementing a second idler gear in the portal box, we ensure an extended surface area for load distribution. This facilitates a more reliable torque transfer and provides you with the strongest gear set available in the market. Furthermore, our two idler gears have been precision CNC ground to guarantee perfect mating. We use only the exceptionally tough 9310 steel alloy to manufacture our gears, ensuring unparalleled durability. Thought dual idlers didn't make a difference? With GDP's unrivalled quality and expertise, we've redefined their significance.
Engage in exhilarating off-road adventures with our GDP Portal Gear Lifts, meticulously engineered for every terrain, time, and riding style. Whether you are navigating trails, mud bogs or vast dunes, our portals elevate every ride, offering you unmatched control and power. Choose a 15% gear reduction for fast-paced rides coupled with a substantial torque increase, or select a 30% gear reduction for the sheer power to drive those huge tires. For maximum strength, add a dual idler gear to your system. Our Can-Am Defender dual idler portals are the go-to choice for riders who won't let anything slow them down. Experience unparalleled performance with GDP Portal Gear Lifts.
A Gear Reduction That Protects Your Drivetrain
Experience an upgraded driving performance with our specialized Portals. These unique devices ingeniously position the gear reduction directly in the hub, post your transmission, prop shaft, differential, and axles. The strategic placement ensures a drastic reduction of stress on your entire drivetrain.

Choose our Portals for a comprehensive win-win - bolstered power and prolonged component lifespan.
