About U-Bolts
U-Bolts on many suspensions provide the force necessary to create what is called the center clamp. This provides the permanent tie between
not only the spring leaves, but between the spring and spring seat as well. The clamp performs the following functions:
- Attach the spring firmly to the axle seat
- Prevent leaf breakage through the center bolt section
- Prevent center bolt breakage due to shear
