Product Description

3.5k Boat Trailer Axle Assembly 73 in Hub Face 58 in Spring Center 5 on 4.5 Idler Hubs and 25 1/4 inch Leaf Springs

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.

SELECTING THE PROPER TRAILER AXLE
When selecting an axle for your application remember to consider the following important specifications:

• LOAD CAPACITY:  the load rating of the axle must support the maximum gross vehicle weight rating. For multiple axle trailers divide the GVWR by the number of axles to determine the minimum load capacity of each axle.

• TRACK LENGTH:  measure your axle track length by determining the distance between the center of one tire to the center of the other tire. A more precise measurement can be made by measuring the distance from one 'HUB FACE' to the other. The hub face is also known as the mounting surface where the wheel studs are located.

• SPRING CENTERS:  measure the distance from the center of one spring to the center of the other.
  NOTE: not required for replacement torsion axles

• OVERALL LENGTH:  measure the distance from the very end of an axle's spindle to the very end of the opposite spindle.

• AXLE STYLE:  important when reusing old mounting hardware and also for proper tire clearance. Includes straight axles (round or square), drop axles with offset spindles, and torsion axles. Also consider spindle size when reusing existing hubs or drums.

• AXLE CAMBER:  Most trailer axles are designed with a bend in the tube that will deflect when the load (weight of the trailer) is applied. This will theoretically bring the trailer wheel camber toward a 0 value that is the best setting for most trailer applications. This will allow the tires to wear evenly and allow the longest tread life. Camber can be affected by damage to the axle. For example, if the axle spindle is bent, this will usually cause a negative camber on that side which will cause excess tread wear on the inside of that tire.
