Unleash Extreme Performance with a 4" Portal Lift
Transform your Yamaha Wolverine X2 850 or X4 850 into the ultimate off-road machine with SuperATV’s GDP 4" Portal Gear Lift. Designed for riders who demand torque, clearance, and drivetrain protection, this portal lift lets you conquer mud, rocks, and trails with confidence. Whether you’re upgrading for bigger tires or tougher terrain, GDP portals give your Wolverine unmatched performance.
Dual Idler® Technology – Patented Strength
Our exclusive Dual Idler® design spreads the load across two idler gears, delivering superior torque transfer and bulletproof reliability. Precision CNC grinding ensures the 9310 steel alloy gears mesh perfectly, maximizing strength while minimizing wear. Dual idlers also provide a 3/4" front and rear offset, resulting in a total of 1.5" extension for improved stability and handling.
Gear Reduction for Torque & Drivetrain Protection
Choose from 15% or 30% gear reductions to match your riding style. The 30% reduction delivers massive torque to turn big tires through mud and over rocks, while 15% keeps your Wolverine responsive on trails and tracks. Because the gear reduction occurs in the portal hub, your axles, differential, driveshaft, and transmission all experience less stress—extending drivetrain life while enhancing off-road capability.
Housing Options Built for Strength
GDP portals come in cast or USA-made billet aluminum housings. Both are reinforced for gear retention, optimized for oil flow, and paired with advanced steel alloy backing plates stronger than chromoly. With no vents and Thermo-Tork® gaskets or O-rings, these portals prevent leaks and keep your drivetrain protected in all conditions.
Complete, Trail-Proven Kit
The kit includes assembled portal hub boxes, universal hubs, slotted rotors, backing plates, caliper mounts, steering arms, extended brake lines, and all hardware needed for a seamless installation. Dual idler portals are tested to handle up to 28" tires on stock suspension and provide maximum torque for extreme terrain.
