Construction & Design

The Fabtech 4.5-inch Performance System is built with durability and performance in mind. The front coil springs are made from high-strength steel to withstand heavy loads and off-road impacts, providing consistent ride height and improved handling. The control links are constructed from robust materials with precise engineering to maintain proper suspension geometry, ensuring optimal caster and camber angles for safe and predictable steering.

The Pitman Arm and trac bar bracket are designed with precision CNC machining, guaranteeing a perfect fit and long-term reliability. The stainless steel Dirt Logic shocks feature a mono-tube design with a large 2.25-inch diameter body, offering excellent heat dissipation and damping control. These shocks are built to endure the rigors of off-road driving while providing a smooth, controlled ride on the street.

Performance & Sound

This suspension system significantly improves your truck's off-road capability by increasing ground clearance and providing superior shock absorption. The Dirt Logic shocks deliver enhanced damping performance, reducing body roll and improving stability during spirited driving or challenging terrain. While this kit does not explicitly claim horsepower gains, the upgraded suspension components help support your vehicle's overall performance and load handling, making it more responsive and capable in demanding conditions.
