Our parts are refined through endless blood; sweat; and hard rides. GDP portals will redefine your RZR 900.

What is a Dual Idler®?
Perfection takes time. After years of research and development; weve made our dual idler gear portals unlike any other. By placing a second idler gear in the portal box; the load gets spread over twice as much surface area for more reliable torque transfer and the strongest gear set you can get. Two idler gears dont do a thing if theyre not mated perfectly; though. Precision CNC grinding ensures ours do. Our gears are made from the industrys toughest 9310 steel alloy. Didnt think dual idlers mattered? With GDPs quality and experience; they finally do.

A Gear Reduction for Any Kind of Ride
Install 6 portals with a 30%; 45%; or 60% gear reduction to get clearance for huge tires and a massive boost in torque. Itll turn your monster tires like theyre stock and take your RZR 900 through the thickest mud holes; over the tallest hills; and down treacherous trails. These portals are all about torque—and they can make the rooster tails that prove it.

Less Drivetrain Wear than Stock
We love that portal gear lifts put the gear reduction directly in the hub. This leads to less stress on your machines most vital parts; even through rough riding. Your axles; differential; prop shaft; and transmission will thank you—and theyll last longer; too.
