Product Details

The Skyjacker BUK4573 is a 4.5-inch rear lift block and U-bolt kit designed to provide additional ground clearance and lift for pickup trucks. This kit includes precision-machined lift blocks and heavy-duty U-bolts engineered to safely raise the rear suspension while maintaining proper axle alignment and load distribution.

Key Features:

  • 4.5-inch rear lift height for aggressive stance and clearance
  • Includes lift blocks and matching U-bolts for complete installation
  • Heavy-duty construction for durability and long-term performance
  • Designed to work with aftermarket wheels with proper backspacing
  • Professional installation recommended

Important Installation Notes:

  • Requires aftermarket wheels with 4-inch backspacing (OEM wheels cannot be reused)
  • Minor modifications may be required on Duramax diesel models
  • For applications requiring add-a-leaf rear lift instead, order Skyjacker part number R3820
  • Compatible with Skyjacker's complete suspension lift systems

Skyjacker Suspension has been manufacturing quality lift kits and suspension components since 1974, delivering reliable performance for trucks and SUVs. This lift block kit provides an economical solution for achieving additional rear lift height when used as part of a complete suspension system.
