Super ATV's GDP 6" Portal Gear Lift gives your RZR Trail 900 a major performance boost with added ground clearance, room for bigger tires, and customizable 30%, 45%, or 60% gear reductions.
For unmatched strength, opt for dual idler gears - precision CNC-ground 9310 steel that evenly distributes load for optimal torque transfer and durability.
With the gear reduction placed in the hub, GDP portals reduce wear on drivetrain components like axles and transmissions. Built to handle anything, they feature cast or billet aluminum housings, thick 5/16" steel alloy backing plates, and no vents (proven ineffective in testing). Advanced gaskets and bearings ensure a tight seal and long-lasting performance.
Whether you're riding dunes, trails, or mud, GDP portals give your Trail 900 the torque, clearance, and toughness it needs. Backed by a dedicated support team, they're built to perform and made to last.
