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

U-Bolt Q&A

Q.  If I'm replacing a spring, can I re-use the old u-bolts?

A.  No, you should never re-use u-bolts. A properly installed U-Bolt stretches a little bit under torque. The results of this small amount of stretching and its effects on the U-Bolt threads and deep nut, lower a used U-Bolt's ability to sustain the required clamping torque.

Q.  Is torque important when I tighten u-bolts?

A.  You bet it is. The following are a list of common problems resulting from improperly torqued u-bolts:
  • looseness in seat area
  • excessive wear on chassis components
  • possible spring breakage
  • possible axle slippage and misalignment
