Gen 3 Portals Are Geared for All
SuperATV’s GDP 6" Portal Gear Lift for the Can-Am Defender HD5 is built for riders who want taller machines, bigger tires, and more power to the ground. Choose a 30%, 45%, or 60% gear reduction, and upgrade to dual idler gears for even greater strength and torque transfer.
GDP portals use the gear reduction in the hub instead of the transmission, helping protect your drivetrain components while keeping factory steering geometry untouched. They’re designed for all riding styles, from trails and dunes to mud and rocks.
Dual idler gear benefits: a second idler gear spreads the load over more surface area for stronger torque transfer. Precision CNC grinding and 9310 steel gears help ensure smooth, reliable operation.
Built for strength and durability
Advanced sealing and bearing design
