5 Lug Galvanized Spare Tire Mount for I-Beam Boat Trailers with #84 Spindle

This Spare Tire mount for 3500 pound hubs is a secure and convenient way to mount a spare hub and wheel assembly to your I-beam boat trailer. The 4 hole mounting plate allows you to easily drill and bolt the mount directly into your trailer's I-beam and safely hold your spare 3500 pound hub and tire assembly securely and away from the road and any hazards. This spare tire mount has a galvanized coating, which protects against corrosion and the elements, making it perfect for boat trailers that see heavy freshwater or saltwater marine use.  The #84 spindle is the standard spindle size for 5 bolt trailer hubs, so select a 3500 lb Galvanized Idler Hub if you need a spare hub to complete your project.
