Super ATV’s GDP 4” Portal Gear Lift for the Yamaha Viking delivers unmatched power, durability, and customization.

Choose between a 15% or 30% gear reduction to suit your riding style - 30% for torque-heavy mud and rock crawling or 15% for faster trail performance. You can also upgrade to a dual idler setup for even greater strength and smoother torque transfer, thanks to precision-ground 9310 steel gears.

These portals reduce drivetrain strain by placing the gear reduction in the hub, protecting your axles, differential, and transmission. Housing options include durable cast aluminum or CNC-machined 6061 billet, paired with advanced steel alloy backing plates. Additional features include high-quality gaskets, double-sealed bearings, and a no-vent design for maximum reliability.

For heavy-duty builds, Super ATV recommends adding a frame stiffener to support the extra stress from portals and big tires. With top-rated customer support and decades of refinement behind them, GDP portals are the strongest, most refined option for your Yamaha Viking.
