This is a universal joint U-bolt kit for heavy-duty truck and equipment drivelines.
It secures the bearing caps of a universal joint to the driveshaft yoke, locking the joint in place so it can transfer torque at an angle. You typically replace these U-bolts whenever you install a new universal joint, because reusing old, stretched hardware can lead to loose caps, vibration, and premature failure of the driveshaft. This specific kit fits 1480 and 1550 series U-joints (Neapco 3-0188 / 3-0155 or equivalent) and includes two U-bolts, four lock washers, and four nuts.
Only fits 1480/1550 series U-joints with 1.375-inch bearing cap diameter. Always verify your U-joint series and cap size before ordering. If your exact vehicle model is uncertain, cross-reference the U-joint part number (e.g., Neapco 3-0188, 3-0155, or Spicer 3-94-28X) rather than the truck make/model.
