If you’re serious about performance, this is where things change.
The 4” Portal Gear Lift isn’t just about lift height, it completely transforms how your KRX puts power to the ground. By moving gear reduction to the hubs, you get more torque, less drivetrain stress, and the ability to run bigger tires without killing your machine.
This is the difference between getting through terrain and dominating it.
