Construction & Design

The Fabtech RTS suspension system features a robust steel construction with precision-engineered brackets and mounting points. The patent-pending bracket system is a standout design that raises the torsion bars to their original location, preserving factory handling characteristics and minimizing wear on suspension components. The system's components are TIG-welded and CNC-machined for exact fitment and durability.

The shocks included are high-performance units designed to provide excellent damping characteristics, ensuring a smooth ride both on and off-road. The lift kit's design emphasizes strength, reliability, and ease of installation, making it a popular choice among off-road enthusiasts and daily drivers alike.

Performance & Sound

With this lift system installed, your GM 2500HD will experience improved ground clearance, allowing you to navigate rough terrains with confidence. The increased height enhances approach and departure angles, making off-road obstacles less daunting. The shocks provide better control and stability, reducing body roll and improving overall handling.

The system does not significantly alter the vehicle's factory sound profile but may produce a more aggressive exhaust note due to increased ground clearance and larger tires. Overall, expect a more commanding presence and improved off-road performance without sacrificing ride comfort on paved roads.

Installation & Fitment

The Fabtech RTS 6" Suspension System is designed as a bolt-on upgrade that can be installed with standard tools and moderate mechanical skill. The system retains the factory torsion bars in their stock location, simplifying the installation process. No cutting, drilling, or extensive modifications are required, although professional installation is recommended to ensure proper alignment and safety.

Once installed, you'll enjoy a significant lift that enhances both the appearance and capability of your GM 2500HD. Proper alignment is essential after installation to maximize handling and tire wear.
