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.

Gen 3 is Geared for All

Just about any kind of rider can benefit from a gear reduction. Our Gen 3 GDP Portal Gear Lifts are available with different gear reductions because getting the right torque isn’t a one-size fits all solution. Which one you need depends on how you use your UTV, but don’t worry, we make choosing the right gear reduction and lift easy.  

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.  

  • Great for rough trail riders, desert riders, and utility vehicles
  • Available with 4” portals
  • Ideal for tire sizes up to 32”

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.

This setup is ultra-focused on being the best at big rocks and deep mud. And it looks awesome. If you want to win the bounty hole, you need a 45% gear reduction.
