Construction & Design

The Fabtech suspension system is built with high-quality materials to withstand the rigors of off-road driving and heavy-duty use. The Dirt Logic shocks feature stainless steel construction, providing excellent corrosion resistance and long-lasting performance. The system's components are engineered with precision, utilizing CAD-designed brackets and heavy-duty steel for the lift blocks and U-bolts. This ensures a secure fit and reliable operation over time.

The use of drop brackets and relocation hardware maintains proper suspension geometry, which is crucial for safety, handling, and tire wear. The design emphasizes ease of installation, with many components designed for bolt-on installation, allowing for a straightforward upgrade process without extensive modifications.

Performance & Sound

This suspension kit significantly improves your truck's off-road capability by increasing ground clearance and wheel travel, allowing you to navigate rough terrains more confidently. The Dirt Logic shocks provide excellent damping, reducing body roll and improving stability during spirited driving or heavy loads. While primarily focused on off-road performance, the system also enhances on-road ride quality by absorbing bumps and vibrations more effectively than stock components.

Installation & Fitment

The Fabtech K2155DL suspension system is designed as a bolt-on upgrade that utilizes existing factory mounting points, making installation straightforward for experienced DIY enthusiasts or professional installers. No cutting, drilling, or extensive modifications are required, and the system is engineered to restore proper suspension geometry after lift installation. Basic mechanical skills and standard tools are sufficient to complete the installation, which typically takes several hours.
