3-Inch Suspension Lift | Factory Bilstein Compatible | Uniball Upper Control Arms | SKU: K2383

Upgrade your Bronco’s suspension performance and off-road capability with the Fabtech 3-Inch Uniball UCA Lift Kit with Front & Rear Shock Spacers (K2383), engineered specifically for 2021–2026 Ford Bronco 4-Door 4WD models equipped with factory Bilstein suspension. This suspension system improves ground clearance, increases wheel travel, and allows for larger tires while maintaining excellent ride quality and factory-style drivability.

The K2383 system provides approximately 3 inches of lift, giving the Bronco a more aggressive stance while allowing clearance for up to 35-inch tires. Fabtech includes heavy-duty 4130 chromoly Uniball upper control arms designed to improve caster geometry, increase articulation, and eliminate the limitations of the factory upper ball joint during aggressive off-road use.

This kit utilizes front and rear shock spacers to retain the factory Bilstein shocks while increasing ride height and suspension capability. Fabtech also includes adjustable rear lower link arms for improved rear axle geometry, articulation, and suspension durability during demanding trail conditions.
