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 33" 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 front Dirt Logic 2.5 Resi Coilovers and Dirt Logic 2.25 rear shocks for aggressive offroad capabilities with a smooth highway ride. The 4" System allows use of 33" tires and is ESC (Electronic Stability Control) and Traction Control compliant.
