Fabtech's 4 inch F150 system utilizes their proven heavy duty construction and design features found in their 6 inch systems but with less lift and at a much lower price. This 4 inch system allows use of 35 inch tall tires and features high arched lower control arm crossmembers constructed of 1/4 inch thick steel for maximum strength. The Fabtech ductile iron steering knuckles retain the stock track width keeping tires under the fender for a clean appearance. Rear lift is accomplished with a block and u-bolt configuration.

The Performance System features Dirt Logic 2.5 Coilover front shocks and Dirt Logic 2.25 rear shocks for aggressive offroad capabilities with a smooth highway ride.

The 4 inch system allows use of 33 inch or 35 inch tires and is ESC (Electronic Stability Control) and Traction Control Compliant.
