Unleash Ultimate Performance with the Yamaha Viking 4" Portal Gear Lift
Transform your Yamaha Viking into a trail-conquering machine with SuperATV’s GDP 4" Portal Gear Lift. Designed for riders who demand power, precision, and reliability, this portal lift system delivers unmatched torque, clearance, and drivetrain protection. Whether you’re tackling rocks, mud, or aggressive off-road terrain, our dual idler portals provide the strength and performance your Viking deserves.
Dual Idler Technology for Maximum Strength
Our Dual Idler® configuration sets the industry standard. By using two precision-ground idler gears made from premium 9310 alloy steel, torque is distributed across twice the surface area for superior load handling. Combined with cast or CNC-machined billet aluminum housings, these portals provide rock-solid reliability, even under extreme conditions.
Choose Your Gear Reduction
Optimize performance for your ride style with 15% or 30% gear reduction options. Select 30% for massive tires and heavy-duty terrain, or 15% for a balance of torque and top-end speed. Because the reduction occurs at the hub, your entire drivetrain—including axles, differential, and transmission—experiences less stress and wear, extending the life of your machine.
Built to Withstand Anything
GDP portals feature reinforced housings, advanced steel alloy backing plates, and Thermo-Tork® gaskets for leak-proof operation. Double-angular contact bearings, sealed input gears, and roller idler bearings ensure smooth performance, while precision engineering keeps gears perfectly meshed for quiet, efficient operation.
Complete Package for Serious Riders
The 4" Portal Gear Lift includes assembled hub boxes, universal hubs, steel caliper mounts, brake lines, and all necessary hardware. Add the optional SuperATV Frame Stiffener to handle the increased stress from larger tires and extreme trail conditions. Designed and tested in the USA, this portal lift system is lighter than the competition and built for long-lasting performance.
Compatibility: Yamaha Viking 2014+ (including EPS, SE, VI, Ranch Editions). Requires 14" or larger wheels with ≤5" backspacing.
