We carry this U-Bolt mostly for the purposes of using on 2 inch Square Galvanized Axles when you are using Single Leaf and (2) Leaf Slipper Springs. Sometimes you can also use this kit with 3 Leaf 24" Slipper springs. The most common U Bolt Kit would be the one using 4 13/16" U Bolts. However, with a smaller capacity leaf spring, using this listing with the 4 5/16" U Bolt is more ideal. Do not select this kit if you are using Double Eye Springs, as more than likely the U Bolt length will not be long enough.
Many times you will select this kit if you are purchasing a 2" Square 2200lb Axle from us to replace your old one, where the old one used the Diagonal Style U Bolts, your new axle will require this style of U-Bolt Mounting Kit.
