Fabtech 4? Performance System w/ Front Dirt Logic 2.5 Coilovaer & Rear Dirt
Fabtech's 4? Performance systems utilize their proven heavy duty construction and design features found in their 6? systems but with less lift for use with 33? tall tires. These 4? systems feature 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 Stainless Steel 2.5 Coilover front shocks and Dirt Logic Stainless Steel 2.25 rear shocks for aggressive offroad capabilities with a smooth highway ride.
