The Importance of U-Bolts

• Seized or Broken U-Bolts: Old U-bolts often seize or break, requiring cutting for removal.
• Damaged Threads: Removing old U-bolts can damage threads, leading to loose U-bolts and voided warranties.
• Incorrect Length: Stronger leaf springs may need longer U-bolts.

• Shape: Square, round, or semi-round.
• Material Size: Measure the rod's diameter at the thread.
• Inside Measurement: Ensure it fits over the differential or spring pack.
• Leg Length: Measure from the underside of the top to the leg end.
• Thread Length: Ensure enough thread for secure fastening.
• Material Grade: Use high-grade materials for durability.

• Re-tension: Re-tighten U-bolts 7-10 days after installation to secure the springs.
• Correct Fit: Ensure U-bolts match your vehicle's specifications.
