  • Description

Replace the Axle, Leaf Springs, U Bolts, and hubs on your trailer all at the same time with this Full Trailer Axle Suspension Assembly.  The 73 inch Hub Face Trailer Axle has a standard 4 hole brake flange and comes with 25 ¼ inch Double Eye Leaf Springs pre-installed with zinc plated U Bolts and U Bolt Plates.  This Painted Steel Axle Kit also features 5 lug (4 ½ inch bolt pattern) Standard Hubs and a 4 Hole Brake Flange so you can install Trailer Disc Brakes to it if needed.  This assembly includes everything except the Leaf Spring Shackles and Leaf Spring Mounting Bolts.  You may also need New Trailer Lug Nuts to complete the project.

 Typically, replacing all the parts on your trailer together like this is difficult to do, and many measurements need to be taken in order to order the correct parts, which need to be sourced individually.  There are some common measurements in the trailer industry though, and these Axle Kits are made with the most common sized parts in mind.  This doesn't mean the Complete Trailer Axle Kit will fit your trailer though, you would need to take measurements from your trailer and compare them to the specifications below in order to guarantee that the parts in this assembly will fit your trailer frame.  If you plan to replace your leaf spring mounting brackets as well, our Single Axle Leaf Spring Slider and Tandem Axle Leaf Spring Slider could make the whole project a lot easier.  Please check all measurements and call or email us with any questions before placing your order.
