Fabtech's new 4" crossmember systems utilize their proven heavy duty construction and design features for a robust suspension upgrade.

The Fabtech ductile iron steering knuckles retain the near stock track width keeping tires under the fender for a clean appearance. Rear lift is accomplished with a block and u bolt configuration.
