Construction & Design

The Fabtech 6" Performance System is constructed with high-quality materials to withstand the demands of off-road driving and heavy-duty use. The control arm crossmembers are fabricated from 1/4-inch thick steel, providing a robust foundation that resists bending and damage. The integrated skid plate is engineered from durable steel to shield vital components from impacts and debris, ensuring longevity and peace of mind during off-road excursions.

The extended-length ductile iron steering knuckles are designed for maximum strength and corrosion resistance, supporting larger wheels and tires while maintaining precise steering response. The coilover reservoirs are engineered for optimal heat dissipation and durability, enhancing damping performance over extended use. Overall, the system's components are meticulously designed and tested to deliver a reliable, long-lasting upgrade that maintains factory-like fitment and handling characteristics.

Performance & Sound

This suspension system significantly improves your Ford F150's off-road capability and on-road ride quality. The upgraded coilovers and shocks provide better damping control, reducing body roll and improving stability during spirited driving or challenging terrain. The larger tires supported by the extended-length knuckles enhance ground clearance and traction, allowing you to conquer obstacles with confidence. While this kit does not specifically alter the vehicle's sound profile, the improved suspension response results in a more composed and controlled driving experience both on and off-road.

Installation & Fitment

The Fabtech 6" Performance System is designed for a bolt-on installation that requires no welding or extensive modifications. The kit features zero holes to drill, and only some cutting is necessary to ensure proper fitment and clearance. The process typically takes around 5 hours for a skilled installer or an experienced DIY enthusiast. The system uses factory mounting points and OEM-style hardware, ensuring a secure and precise fit. No additional tuning or alignment adjustments are usually required, but a professional alignment is recommended after installation to optimize handling and tire wear.
