SuperPro Leaf Spring U-Bolt 12x72x170 Square

The Importance of U-Bolts

The humble U-bolt is crucial for your vehicle's suspension, especially if you have leaf spring suspension. It secures the leaf springs to the differential, which houses the axles and keeps your wheels and tires on the road.

Why Replace 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.

Essential Questions About 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.

Tips for U-Bolt Replacement

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