U Bolts & Kits
To complete the total spring kit selection, you need to identify the U bolt kit that is appropriate.
U bolt kits contain the U bolts, nuts & washers, axle pads and fish plates.
Each U BOLT KIT contains components for ONE axle only. When ordering for a multi axle application, order the number of kits to correspond with the number of axles.
To select your U bolt kit:
- Identify what width of spring you are using: 45mm or 60mm
- Identify the number of spring leaves, i.e. 2,3,7,etc.
- Identify the section of the axle, i.e. 39mm round, 50mm square etc.
Simply read across the tables to find the appropriate part number for the U bolt kit you require.
