Bigger Tires and Better Performance
SuperATV's GDP Portals for your Polaris Scrambler give your machine the power to perform at its best. You get an all-in-one gear reduction and 8” lift, giving you the ability to run large tires and master any terrain. The portals come with 45% gear reduction. Upgrade from cast to billet aluminum housing for ultimate strength.
Conquer Every Terrain
Dominate any terrain with confidence when you install GDP Portals on your Polaris Scrambler. More ground clearance allows for bigger tires. With a 45% gear reduction, you’re getting maximum torque. This makes it so you can turn large tires as if they were stock size.
Minimize the Strain on Your Drivetrain
With GDP Portals, you’re putting the gear reduction in the wheel hub instead of the transmission, giving your drivetrain extra protection. It’ll put less stress on your axles, prop shaft, differential, and transmission. This could save you from costly repairs.
Maximum Strength and Durability
You want portals that you can count on. SuperATV’s GDP Portals are offered with cast or billet aluminum housing. Combine that with SuperATV's 5/16” backing plates made of advanced steel alloy and you’re getting the best portals in the industry.
The 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—SuperATV knows because it tested them
Advanced Gaskets, Seals, and Bearings
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 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
