A Quiet Ride
SuperATV GDP Portals are quiet because we precision grind all of our gears to fit so snugly that you couldn’t get a fingernail between them. That combined with the fact that they’re made with 9310 billet steel alloy means less vibration, less friction, and better performance. Each precision-ground gear makes for a quieter ride with no “clicking.” With thousands of riders logging hundreds of thousands of ride hours on their portals, you can trust GDP to be the most proven portal gear lift you can get. That's not something you'll find anywhere else.
