Gen 3 Portals Are Geared for All
When it comes to side-by-sides, one size does not fit all riders. Your machine should be as unique as you are, and this GDP 4" Portal Gear Lift was designed with that in mind. It adds both a lift and a gear reduction to your Polaris RZR Trail 900, with your choice of 15% or 30% reduction and cast or billet aluminum housings.
More riders turn to SuperATV for portal needs than anyone else in the industry thanks to extensive design, field, and lab testing. This portal gear lift is built to help take your ride to the next level.
Perfect for mud, the 4" lift helps keep you from getting swamped and gives you room for bigger tires, while the gear reduction adds torque to help you cut through thick conditions.
Portal gear lifts place the gear reduction directly in the hub, which helps reduce stress on your axles, differential, prop shaft, and transmission for improved drivetrain protection.
The portals use premium 9310 alloy steel gears that are precision ground for proper mating and quiet operation. Housing options include cast or USA-made 6061 billet aluminum with CNC-machined finish, reinforced design, and no vents. Both housing styles use advanced oil-resistant gaskets, a sealed input gear, and a double-lipped output seal. They also use strong roller bearings and a double-angular contact output bearing for durability.
All GDP portals utilize precision-ground stainless steel slotted rotors and universal hubs with 4/156, 4/137, 4/115, and 4/110 bolt patterns. The tapered output shaft provides a more secure lock to help prevent wobble over time.
