4-inch performance exhaust system featuring dual mufflers, resonator, and rear muffler assembly—designed specifically for 2009–2013 Ford F-150 4WD models

Description

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.
