Construction & Design:

Fabtech’s coil springs are manufactured from premium-grade steel, engineered to withstand the rigors of off-road driving while maintaining a smooth on-road ride. The dual rate design means the springs have two distinct compression rates: a softer initial rate for absorbing minor road imperfections and a firmer secondary rate to handle heavier loads and larger impacts. This progressive spring rate ensures optimal performance across a wide range of driving conditions.

Each spring is precision wound and heat-treated to enhance strength and durability. The corner-specific design accounts for weight distribution differences on each side of the vehicle, resulting in a level stance and improved handling characteristics. Fabtech’s commitment to quality craftsmanship guarantees springs that resist sagging and maintain their lift height over time.

The kit lifts the vehicle evenly by 3 inches front and rear, improving ground clearance and off-road capability while preserving factory ride quality.
