Fabtech's 4'' F150 system utilizes their proven heavy duty construction and design features found in their 6'' systems but with less lift and at a much lower price. This 4'' System allows use of 35'' tall tires and features high arched lower control arm crossmembers constructed of 1/4 '' 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'' System allows use of 33'' or 35'' tires and is ESC (Electronic Stability Control) and Traction Control compliant.
