Fabtech 6in Performance Suspension System

2003–2008 Hummer H2 SUV/SUT 4WD

Part #: K5000DL

Overview

The Fabtech 6-inch Performance Suspension System is designed specifically for Hummer H2 owners who demand exceptional off-road capability combined with improved on-road comfort. Built with durability and performance in mind, this system elevates your vehicle by six inches, providing increased ground clearance and the ability to tackle challenging terrains with confidence. Whether you're an avid off-roader, a weekend adventurer, or someone looking to enhance your H2's appearance and capability, this suspension kit offers a comprehensive upgrade.

Engineered to address the unique needs of the H2's full-time transfer case and heavy-duty build, this system ensures your vehicle maintains smooth driveline operation and reliable performance. The kit is ideal for those seeking a significant lift for larger tires, improved approach and departure angles, and enhanced off-road prowess without sacrificing daily drivability.

Key Features

The Fabtech H2 suspension system incorporates several innovative features that set it apart from standard lift kits:

• Extended steering knuckles and high-clearance crossmembers designed to maximize ground clearance and approach angles, allowing your H2 to navigate rough terrain more effectively.
• A CV style front driveshaft included to properly address the full-time transfer case, ensuring smooth and reliable driveline operation even under demanding off-road conditions.
• Two 1/4'' thick skid plates—one for the front differential and one for the transfer case—providing robust protection against rocks, debris, and rough terrain, thereby safeguarding vital drivetrain components.
• Heavy-duty leaf springs and coil springs engineered to support the increased ride height and load capacity, maintaining ride quality and vehicle stability.
• High-quality materials and TIG-welded construction for durability and long-lasting performance in extreme conditions.
• Designed to work seamlessly with factory air bag systems, with rear lift achieved through stout bag spacers that maintain ride comfort and load support.
• Optimized geometry to preserve factory handling characteristics while delivering a commanding stance and improved off-road capability.

Construction & Design

The Fabtech suspension system features a meticulously engineered design that combines strength, functionality, and ease of installation. The extended steering knuckles and high-clearance crossmembers are crafted from high-strength steel, ensuring durability and resistance to bending or cracking during aggressive off-road use. The skid plates are made from thick steel to withstand impacts from rocks and debris, providing essential protection for the differential and transfer case.

The system's components are TIG-welded for precision and strength, and the use of high-quality materials ensures longevity even in harsh environments. The inclusion of a CV style front driveshaft addresses the unique drivetrain layout of the H2, ensuring smooth power transfer and reducing driveline vibrations. Overall, the design maintains factory-like handling and ride quality while significantly enhancing off-road performance and ground clearance.

Performance & Sound

With this suspension upgrade, your Hummer H2 will experience improved off-road capability, including increased ground clearance, better approach and departure angles, and enhanced articulation. The system supports larger tires, which further boosts traction and capability. While specific horsepower or torque gains are not claimed, the increased clearance and improved suspension geometry contribute to better overall vehicle performance and handling in challenging conditions.

The ride remains comfortable on paved roads, with no excessive noise or harshness introduced by the lift components. The system is designed to provide a balanced blend of off-road prowess and on-road comfort, making it suitable for daily driving and weekend adventures alike.
