SUPERATV Polaris RZR RS1 8" Portal Gear Lift

Polaris RZR RS1 8” Portal Gear Lift 

The Portal Advantage 
The ultimate UTV lift technology just got bigger with SuperATV’s 8” Portal Gear Lift for the Polaris RZR RS1. It doesn’t get any better than a massive 8-inch lift that maintains your axle geometry. The 45 percent gear reduction gives you all the torque you need to push 40” tires through thick mud and over massive boulders. It’s Gear Driven Performance at its finest. 

NEW to 8” Portals 
Our 8” portals for the RZR RS1 feature a 1.5” forward and rear offset. This gives you room for bigger tires—up to 40” 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? 
The 45 percent gear reduction (1.82:1 gear ratio) you get with a GDP Portal Gear lift lets you install the nastiest tires you can find all without worrying about whether your RZR’s axles and driveline can handle it. Tons of clearance, tons of power, and absolute lifted freedom — that’s what Gear Driven Performance is all about. 

 

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 RZR RS1, 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.
