GDP Portals Turn Your Ridge into a Powerhouse

Your Kawasaki Ridge hasn’t reached its full potential—until you’ve installed GDP Portals. SuperATV’s 6" Portal Gear Lift gives you a lift and gear reduction in one package. Available with a cast or billet aluminum housing and a choice of 30% or 45% gear reduction, it lets you fit up to 33" tires while conquering tough terrain.

GDP Portals give your Kawasaki Ridge the power it needs to tackle mud, rock crawling, and larger tires. Choose a 45% gear reduction for maximum torque, or go with 30% if you want to keep your top speed while still boosting torque.

Adding more power is great—until it puts stress on your drivetrain. This 6" Portal Gear Lift places the gear reduction in the wheel hub instead of the transmission, helping protect your axles, prop shaft, differential, and transmission by reducing strain on them.

Built to take a beating, GDP Portals feature billet aluminum housings and heavy-duty 5/16" steel alloy backing plates. The housings are reinforced for gear retention and optimized for oil flow, and the advanced steel alloy backing plates are stronger than chromoly. You can also enhance performance with Portal Blood gear oil formulated for GDP Portals. There are no gimmicks and no vents because vents do more harm than good.

The portals use advanced gaskets and O-rings with excellent oil resistance and low deterioration rates, a sealed input gear and double-lipped output seal, 100% sealing coverage throughout, double-angular contact output bearings to prevent premature wear, and roller idler and drive bearings to maintain perfect gear meshing.

If you need help figuring out which gear reduction is right for you, check out our portal gear reduction calculator.
