Why Do You Need a Gear Reduction?
You need a gear reduction because you either want more torque, to turn bigger tires or to get more power while using the tires you already have. Either way, with a gear reduction, you get the right torque for the right tire size and the right riding style for you.
- More Torque
Boosting your torque means you can accelerate quicker and your tires can roll over tough terrain without your engine hitting higher RPMs. You can take your machine through deep mud and over crazy boulders without your tires getting stuck. A lift with a gear reduction can give you tons of power to the ground. - Bigger Tires
Running bigger tires robs your torque. They make your machine feel sluggish and crawling over obstacles can tax many UTV engines beyond their capabilities and destroy your drivetrain. Portals put the gear reduction right in the hub, meaning you get more power without putting as much stress on your drivetrain.

15% Gear Reduction
Who can’t use a little extra torque to get over hills and rocks. The difference in top speed is almost imperceptible, but the extra oomph you get is anything but. Hitting the gas from a dead stop will feel better, and your machine will be more capable over every bump, rock, and hill. A little bigger tire and a small gear reduction make driving over ditches and debris easy.
Hauling a trailer will be easier with more torque, and the smaller 4” lift gives you ground clearance without making it difficult to load the dump bed. Not to mention, your UTV can still hit those high speeds you need to when you’re riding on the roads between fields. It just lets your machine do more.

30% Gear Reduction
Big tires and a 30% gear reduction let the average rider get wild. You’ll be able to enjoy crazy rock gardens, mud holes, and hills. With this setup, you will still be able to ride it through other types of terrain and hit high speeds. It’s great for just about everything.
They also let you run larger tires easily. A 30% gear reduction is perfect for 32” to 40” tires depending on what machine you have. With bigger tires, you can go deeper and crawl harder. Your extra clearance means you’ll keep your machine from getting stuck in the rocks and keep your head above the mud.

- Ideal for tire sizes up to 38” or more

There’s a good reason the biggest reduction comes on the biggest lifts — if you’re going for a reduction this big, you want the biggest tires you can fit on your machine. You’re aiming to tackle the most insane terrain you can find.
That means rolling right over monster rock gardens and plowing through Olympic sized mud holes. The sky’s the limit when it comes to tire size.
