SUPERATV Polaris Ranger Full Size XP 570 Crew 8" Portal Gear Lift

Polaris Ranger Full Size XP 570 Crew 8” Portal Gear Lift 

The Portal Advantage 
Ready to go big? With SuperATV’s 8” Portal Gear Lift installed on your Polaris Ranger 570 Crew Full Size, you can go bigger than you thought possible—bigger tires, bigger mud bogs. Thanks to a 45% gear reduction, your machine will have enough torque to feel like it’s running stock tires on flat ground. It maintains your axle geometry so your drivetrain lasts longer. Gear Driven Performance gives you so much torque back, you’ll think we switched out your engine. 

NEW to 8” Portals 
Our 8” portals for the Ranger feature a 1.5” forward and rear offset. This gives you room for bigger tires—up to 34” without any other modifications. 

The drive gear now seals internally against the housing, not the axle. Even if your axle is dirty, dinged up, or otherwise well-used, the drive gear still seals perfectly and keeps all contaminates out of your portal box. 

To ensure the rest of the box is sealed, we utilize a new O-ring gasket in a machined groove that keeps oil in and mud out, no matter how deep you go. 

45% Gear Reduction? 
Sure, Gear Driven Performance means you get a 45% gear reduction (1.82:1 gear ratio) — AKA a whole ton of torque. What that means is you can put monster tires on your Ranger without destroying your drivetrain. These portal gear lifts maintain your stock axle geometry so they last longer while giving you a massive 8” lift at the same time. When you see GDP stamped on your hub, you know it means you’re in for a good time.

What Are Micro Polished Gears? 
If you want maximum performance, choose our precision ground Micro Polished Gears. Micro Polishing is a process that gently smooths out any imperfections in the surface of the metal during a two-stage, non-abrasive, burnishing process that produces a chrome-like finish. The result is unbelievably smooth gears that have almost zero friction or resistance. This means better oil retention and a longer lifetime than other gears. They will stay cool and quiet, while giving you a little more power to the ground.

Do I need a Frame Stiffener? 
Yes, we highly recommend running a SuperATV Frame Stiffener with your 8" Portal Gear Lift. Why? When you push the limits and go big with your Ranger 570 Crew, the stock frame just doesn't have what it takes. Drive too fast or bump too hard and the OEM frame will bend. Trust us — we've done it. A frame stiffener reinforces your frame enough to let you ride your 8" portals with monster tires and no worries.
