Perfect for Mud Mud and portals go hand in hand”they™re a match made in heaven, if you will. You™ll need the extra 6 of lift to cut through those deep, swampy mud pits without getting stuck. And without a gear reduction, you may not have the torque you need to keep your wheels spinning. If you thought mud was fun before, just wait until you try it with these Teryx S 6 portals. A Gear Reduction That Protects Your Drivetrain Some modifications place the gear reduction in your drivetrain which places unnecessary stress on your axles, prop shaft, and transmission. Luckily, GDP Portals don™t fall into that category. We place the gear reduction directly in the hub to greatly reduce the amount of strain placed on your Teryx™s most vital parts. You™ll get more life out of your drivetrain, and you™ll save money and hassle in the long run. Learn more about how tire size and gear reduction can unleash your machine™s potential.
