Polaris Sportsman XP 8" Portal Gear Lift

Maximize Performance with GDP Portals
You want your machine to perform at its best. With our Polaris Sportsman XP GDP Portals, that's possible. SuperATV is the only company that offers portals for your Sportsman. With an all-in-one 45% reduction and 8" lift, you're getting the ability to run bigger tires and take on any terrain. Upgrade from cast to billet aluminum for optimal strength.

Dominate Any Terrain
Conquer any terrain confidently with GDP Portals for your Polaris Sportsman XP. They give you the clearance to run massive tires. With a 45% gear reduction, you're getting ultimate torque you'll be able to turn the biggest tires as if they were stock size.

Keep the Strain on Your Drivetrain to a Minimum
GDP Portals put the gear reduction in the wheel hub instead of in the transmission. Having it in the wheel hub gives your axles, prop shaft, differential, and transmission better protection. You're getting more power without wearing down your drivetrain.

Optimal Durability
You need portals that are built to withstand anything so you can ride rough with confidence. Our GDP Portals come in a cast or billet aluminum housing. That and our 5/16" backing plates made of advanced steel alloy make our portals the best in the game!

• Our housings are reinforced for gear retention and optimized for oil flow
• Advanced steel alloy backing plates are stronger than chromoly
• Enhance with Portal Blood gear oil formulated for GDP Portals
• There are no gimmicks and no vents because vents do more harm than good we know because we tested them

Advanced Gaskets, Seals, and Bearings
Our 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 so you can forget about oil leaks
• Double-angular contact output bearings to prevent premature wear
• Roller idler and drive bearings to maintain perfect gear meshing
