Gen 3 Portals are Geared for All A 6” GDP Portal Gear Lift doesn’t make your ride one particular way. It lets you ride however you want. Whether you want a 45% gear reduction or a 30% gear reduction, you can take your Can-Am Commander wherever you want. The gear reduction gives you tons of torque to turn big tires or push through tougher obstacles, and that huge amount of ground clearance means you’ll get over anything.
GDP—the Most Trusted Name in Portals Pay attention to the lifts people are running out at the parks and you’ll quickly realize that more riders roll on GDP Portals than any other portal system. There are thousands getting put to work every weekend on the trails, in the mud, and on everything in between. There’s no kit more trail proven.
Perfect for Mud Portals and mud are a perfect pair. That ground clearance gives you room for those big mud tires you’ve been eyeing, and the gear reduction gives you the torque to turn them and push through the thickest peanut butter mud. There’s a reason why you see so many GDP portals at every mud park in America.
A Gear Reduction That Protects Your Drivetrain Portals reduce the stress on your axles, differential, prop shaft, and transmission by having the gear reduction right in the hub instead of the transmission. That means you get to have more fun than stock while doing less damage than stock. It’s a win-win.
Unmatched Gear Material The most important part of a portal gear lift is, of course, the gears. Our top-of-the-line gears are made with precision-ground 9310 alloy steel that’s built to take on extreme forces. They mate perfectly each and every time to give you super quiet portals that run smooth even when you’re pinning the needle.
Stronger Housings by Design Our cast aluminum and USA-made billet aluminum housings are both made to have extreme strength. We know how to make them strong because we’ve made tens of thousands of them. We have the experience. We’re not just taking a shot in the dark and neither should you.
- Our housings are reinforced in all the right places
- They’re built with better oil flow and gearing forces in mind
- There are no gimmicks and no vents because vents do more harm than good—we know because we tested them
The Strongest Portal Backing Plates You Can Get The portal backing plates hold your suspension and your hub together—they’re pretty important. That’s why we use an advanced alloy steel that’s stronger than chromoly and we make them 5/16” thick to make them virtually bulletproof. They’ll outlast your machine’s lifetime because that’s how strong they have to be.
Advanced Gaskets and Seals Whether you go with cast or billet, both housings use:
- Advanced Thermo-Tork® gaskets with excellent oil resistance and a lower deterioration rate than Kevlar gaskets
- A sealed input gear and double-lipped output seal
- 100% sealing coverage throughout so you can forget about oil leaks
Bearings That Rock The smallest details can make the difference between a portal kit that rocks and a portal kit that sucks. That’s why even our bearings are the best. We use a double-angular contact bearing to stabilize our output shaft because it can take hit after hit without wearing prematurely. Our idler bearings see huge internal torque loads so we make them beefier with roller bearings. Altogether your getting a box that has uncompromising strength inside and out.
Universal Hubs and Slotted Rotors Our precision-ground, stainless steel rotors are slotted to stay cool so you get the braking power you need when you need it. Our universal hubs are made with convenience in mind. With 4/156, 4/137, 4/115, and 4/110 bolt patterns and lugs, you can fit almost any side-by-side wheel on them. We invented the tapered output shaft that our hubs attach to. It provides a more secure lock that won’t wobble or wear over time.
Extended Trailing Arms Designed for Rhino Axles These portals utilize 4” extended rear trailing arms that give you stability and room for larger rear tires. They require Rhino or Rhino 2.0 axles because they give give you the articulation you need to get wild with that 4” longer wheelbase. Plus, they give you chromoly strength that can’t be beat.
