Construction & Design

The Fabtech 4" Basic Suspension System features high-quality materials and meticulous engineering to ensure durability and performance. The main components, including the control arms and crossmembers, are constructed from 1/4-inch thick steel, providing exceptional strength and resistance to bending or breaking under stress. The high arched design of the lower control arms not only enhances strength but also improves suspension travel and articulation, which is crucial for off-road performance.

The ductile iron steering knuckles are engineered to retain the stock track width, maintaining proper steering geometry and minimizing wear. The rear lift blocks are made from durable steel and are paired with heavy-duty u-bolts to ensure secure axle positioning. The system's design emphasizes ease of installation, with bolt-on components that do not require cutting or extensive modifications. The included performance shocks are engineered for optimal damping, providing a smooth ride and responsive handling across various terrains.

Performance & Sound

This suspension system enhances your truck's off-road capability by increasing ground clearance and improving suspension articulation. The upgraded shocks help absorb bumps and impacts, resulting in a more comfortable ride both on and off the pavement. While specific horsepower or torque gains are not claimed, the system supports larger tires and improved suspension geometry, which can contribute to better overall vehicle performance and handling. The design also helps maintain a factory-like ride quality, ensuring your truck remains comfortable during daily driving.
