The Portal Advantage?
Put a 6" Portal Gear Lift from SuperATV on your Can-Am Defender and you’ll never ride the same way again. With Portal Gear Lifts you get a massive 6” lift and a 45% gear reduction in one package. The gear reduction saves your axles and gives you more torque. You can turn massive tires easily! All that alongside six extra inches of clearance. Sounds great doesn’t it? That’s what Gear Driven Performance by SuperATV is all about.
45% Gear Reduction?
With a 45 percent gear reduction (1.82:1 ratio), you can do anything you want. That means freedom to run huge tires that still feel like stock. With Gear Driven Performance, you’re getting more than a gear ratio — you get freedom. Push your UTV harder than you ever have before without breaking an axle or a prop shaft. Ride higher over any obstacle. Gear Driven Performance means freedom and fun.?
Note: SuperATV strongly recommends installing a SuperATV 6” Defender Lift Kit or other big lift kit in order to fit up to 39" tires. Without the addition of a 6" lift kit, only 29" tires on 18" wheels will fit without rubbing.
