Make Your RZR a Mud MonsterIf you want to take on the nastiest, sloppiest mud, you need SuperATV's Polaris RZR Pro R 8" Portal Gear Lift. It gives you the clearance you need to take on even the thickest muck with confidence. You can customize your GDP with a 45%, 60%, or 70% gear reduction and a billet or cast aluminum housing to transform your RZR into the mud monster of your dreams.
What's a Dual Idler?
We spent years testing and refining our dual idler gear portals to reach perfection. The two idler gears are CNC-ground for a flawless fit that gives you more reliable torque transfer and better overall performance. They're made with durable 9210 steel alloy for longevity too. With GDP's quality and experience, you know you're getting a hardcore portal that can carry your RZR over every obstacle in its path.
Pick What You Want with 45%, 60%, and 70% Gear Reductions
We all know that big tires = badass riding. But they're not just for looks—big tires help you make giant mud pits look like mud puddles. These 8†GDP Portals give you the room and the gear reduction you need to get HUGE tires on your Pro R. But big tires take a lot of power to get them rolling. You have your choice of a 45%, 60%, or 70% gear reduction to help with that. Gear reductions help redistribute power once you've added those massive tires, so your machine's performance doesn't have to suffer.
Protect Your Drive Train
With portals, the gear reduction happens right in the hub. That means you're putting less stress on your drivetrain trying to move those big ol' tires. Your axles, differential, prop shafts, and transmission will thank you for adding GDP Portals.
Learn more about how tire size and gear reduction can unleash your machine's potential.
Housings and Backing Plates Built Tough
We make GDP Portals to put up with the worst abuse UTV owners can dream up. Whether you go with cast or 6061 billet aluminum housings, you'll get incredible strength thanks to our trail-tested design. Pair that with 5/16†backing plates made with advanced steel alloy and you've got the roughest, toughest portals on the market. Does your RZR deserve anything less?
- 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

Worth it.
Size: Small, Color: Black (001)/White
Living in North Dakota, staying warm is invaluable. UnderArmour Cold Gear is the only base layer the provides warmth, KEEPS warmth, and protects from the unforgiving wind. Every winter I go on the hunt for thermals, layering options and I always find others to be saggy or incredibly tight, either way, once I begin shoveling or snowblowering, and sweating, other products become soaked, sticking to skin, unbreathable and quickly your sweat stuck to your body under layers in now creating a cold,chill, freeze to your body, and on a -10F day, it can become a dangerous situation.
I honestly was hesitant to purchase UnderArmour, I felt it was too hyped up or paying for a name. BUT IT IS NOT. UnderArmour isn't a name, it is a company that has made the highest quality base layer, warmth, breathable and it really wicks sweat away; I may not know how it does it, but it works!
For sizing, I ordered a small in the women's longsleeve/turtleneck black coldgear. I'm 5ft and roughly 110lbs. I like the fit, it is meant to fit your body. I probably could wear an extra small, but I like the sleeve length in the small and it fits very well.
Stay warm folks!

Great cold gear
Size: Large, Color: White (100)/Black
Warm, very comfortable. I wear these all winter. The neck can be a little tight and the cut is definitely fitting. Its got thin like fleece on the inside that keeps you warm.

Tight but stays in place, comfy and keeps you warm
Size: Medium, Color: Charcoal Light Heather (019)/Black
I liked this shirt because it keeps me warm when I'm outside even at negative temperatures, I can work out comfortably in it and the sweat dries out soon; also, the interior of the shirt is made of a very comfortable material.
I don't like that this is very tight, cool if you want to use it under your usual sports clothes but if you want to use it as is I would suggest going up a size.
I use this shirt almost every day to work out during winter time, I've washed them several times and they still feel as comfortable as the first day.

Perfect for running!
Size: Small, Color: Black (001)/White
None of my running clothes make me feel as sexy as this underarmor does. It is so soft on the inside, which is an upgrade from their old version because I found one at the thrift store that is really scratchy. It has been through a cold wash and the dryer multiple times at this point and it is still holding up. The size is true. The material thickness is perfect for me between 45-35° F. And again with layers between 15-10° F. But I look forward more to my runs that I get to wear my underarmor. Nothing makes me feel more confident on the trail. And I love love love the turtleneck. I got all black because that is my favorite color to wear when I run and it looks perfect. It is a true black.
