Boat Trailer Axles

Boat Trailer Axles are available in both Square Galvanized and Round Painted Steel Tubing. Each style of axle is more ideal for different boat trailer environments. In addition, Each type of boat trailer axle is available in many lengths and capacities. Typically the 2 x 2 Galvanized Axles are used with Boat Trailers spending most of their useful life in Saltwater environments, while the Painted Steel 2 3/8" Round Axles would be used in mostly Freshwater Environments. The Two Main differences between these axles would be the Shape and the Construction. The Square Shape of the Galvanized Axle requires using 2" Square U-Bolts to Mount it to your trailers leaf springs, while the Round Painted Steel axle requires 2 3/8" Round U-Bolts for mounting to your leaf springs. 

Boat Trailer Trailer Axles are not necessarily Brand Name Specific. For instance, you don't have to replace your current Galvanized Trailer Axle on your Magic Tilt, Continental, Ez Loader, or any other brand named trailer, with their brand galvanized trailer axle. Essentially, the most important factors to replace your current axle are carrying capacity and length. Boat Trailer Axles are mounted to your leaf springs using U-Bolts that are specific for the axle dimension and leaf spring size you are using. When purchasing a new axle, it would be ideal to also purchase the correct U-Bolt Kit for that axle. For Questions of How to Measure your trailer axle, refer to the "How To Measure Your Axle" Tab on the top of your screen, this will guide you through all the correct measurements needed to get a proper replacement axle for your trailer.
