4.5" 2007-2013 GMC Sierra 1500 4WD Lift Kit (w/Loaded Front Struts & Rear Shocks) by Zone

ZONC8LN 4.5" Lift Kit improves ground clearance, stance, and off-road capability on 2007–2013 GMC Sierra 1500 trucks while maintaining factory ride quality and handling characteristics. Designed as a complete suspension system, this kit allows for up to 33" tire fitment while properly correcting suspension and steering geometry for reliable performance at increased ride height.

This configuration includes full-length Zone Nitro loaded front struts paired with Zone Nitro Series rear shocks, providing a complete and balanced suspension setup with consistent damping and straightforward bolt-on installation. High-clearance, heavy-duty crossmembers and multipoint differential relocation brackets improve strength while maintaining proper CV angles. A full skid plate system adds protection and rigidity to the front suspension assembly for demanding off-road use.

Steering geometry is corrected with CNC-machined ductile-iron steering knuckles that maintain proper angles and compatibility with factory components. Additional components, including sway bar relocation brackets, bump stop extensions, brake line brackets, and CV spacers, ensure proper operation and durability across the full range of suspension travel.

In the rear, a replacement lift block and extended U-bolts level the stance while retaining factory ride quality and load capacity. Engineered for durability and backed by Factory Protection Plus, this lift kit provides a dependable upgrade for drivers looking to enhance both performance and appearance without sacrificing everyday usability.
