The Skyjacker BUK4560 Block and U-Bolt Kit provides a reliable solution for adding rear lift to your truck or SUV. This complete kit includes precision-engineered lift blocks and corrosion-resistant U-bolts designed to work together for optimal suspension performance.

Key Features:

• Ductile iron lift blocks with fixed center pins for strength and stability
• Tapered block design corrects pinion angle and prevents driveline vibrations
• E-coated U-bolts provide superior corrosion resistance for long-lasting durability
• Available in multiple lift heights ranging from 1.25 to 5 inches

Skyjacker's block and U-bolt kits are engineered to maintain proper driveline geometry while providing the lift you need. The tapered block design is critical for correcting pinion angle, which helps eliminate vibrations and premature wear on drivetrain components. The fixed center pins ensure the blocks stay properly positioned during installation and use.
