A Gear Reduction That Protects Your Drivetrain
Portal gear lifts place the gear reduction in your hub, which greatly reduces the amount of stress placed on your vehicles most critical components. This means you can relax and go hard knowing that your axles, differential, prop shaft, and transmission aren't being abused.

Bearings That Rock
The performance of a portal gear lift depends on the quality of the bearings inside.

With bearings this good, you know your GDP portals are built to last.
