SuperATV GDP 4" Cast Aluminum 30% Gear Reduction Portal Gear Lift For Big Lift Kit

Ride when, where, and how you want with SuperATV’s GDP 4 Portal Gear Lift. GDP Portals are built to go everywhere you do portals thrive in dunes, desert, trails, and mud they’re built for versatility. If you want the ultimate geared down, torqued up ride for monster tires, go with a 30% gear reduction. Portals put the gear reduction in the hub, which greatly reduces the amount of stress put on your vehicle’s most crucial components. Knowing that your axles, differential, prop shaft, and transmission are in good hands lets you ride harder without worry. Every part starts with strength at its core, and these portals are no exception. These cast aluminum housings are the thickest and strongest you can get. Combine that with 5/16" backing plates made from an advanced steel alloy, and these portals are unstoppable. Extra ground clearance and bigger tires lead to more action packed rides. To stay confident while you put pedal to the metal, consider adding a SuperATV Frame Stiffener when installing your new portals.
