Whether you prefer cast or billet aluminum housing and the added strength of dual idler bearings, the GDP Portal Gear Lift ensures that no trail is too challenging when you're riding on it.

Ideal for All Types of Riders

If you're a fan of off-roading, you'll be amazed by the mud-slinging capabilities of a 30% gear reduction offered by Honda Pioneer 520 portals. With larger tires and enhanced torque, you can effortlessly conquer even the thickest mud that used to slow you down. Our 30% gear reduction excels in various terrains, but if you prefer maintaining a higher top speed, the 15% option provides robust power without sacrificing your UTV's maximum velocity.
