The Carli Suspension CS-FUBK-11 Add-A-Pack U-Bolt Kit is designed specifically for 2011-2016 Ford F250 and F350 4x4 trucks when adding supplemental leaf springs to the rear suspension. This kit provides the necessary hardware to secure add-a-pack leaf springs to the factory rear axle assembly.

Key Features:

• 3-inch semi-square internal diameter design to match 2011-2016 Ford Super Duty rear axle geometry
• 5/8-inch diameter threaded u-bolts for secure clamping force
• Includes all necessary nuts and washers for complete installation
• Manufactured to Carli Suspension's quality standards for durability and reliability
• Designed for use with add-a-pack leaf spring configurations

These u-bolts are essential components when upgrading your Super Duty's payload capacity with additional leaf springs. The semi-square profile ensures proper fitment around the rear axle tube, while the heavy-duty construction provides the clamping strength needed to keep springs securely mounted under load. Compatible with both factory and aftermarket add-a-pack leaf spring kits for 2011-2016 Ford F250/F350 4WD models.
