1000s of Riders, 1000s of Miles

With hundreds of thousands of ride hours, there’s no portal lift in the industry that’s more used and more trusted. More riders roll on GDP than any other portal system. If you want trail-proven fortitude, you want GDP.

Better by Design

Our engineers have been refining GDP housings for years—we know what makes them break and how to make them strong enough to last. Whether you go with cast or 6061 billet aluminum, you’ll get strength built with experience. Our housings are reinforced in all the right areas and are built with better oil flow and gearing forces in mind.
