The axle, large (rear wheel only) is a replacement part that is made by Polaris. It is also made from the same high-grade material used to make the original factory part. Making this a genuine OEM part you can trust.
This axle assembly was designed to house the external parts that help aid in the maneuverability of the cleaner. Such parts as the wheels, tires (max trax), ball bearings, and wheel washers. When these parts are combined, they give the cleaner the ability to cover the entire surface of your pool while it sucks and pulls up dirt and debris.
This part is bolted to the bottom of the frame and is white which can be easy to find and replace near the wheel assemblies. It is attached by two pan head screws w/ lock washers. This ensures no movement or impediment during the operating process.
