More info

The 4” Ultimate System is available with our Uniball Upper Control Arms that feature .120” wall 4130 Chromoly tubing with a 1.50” OD 1” FK Stainless PTFE Uniballs for 9” of front wheel travel. The system also includes heavy duty ductile iron steering knuckles and forged adjusting torsion bar keys to provide the proper amount of lift without CV bind.

 

The system will level the stance of the vehicle compared to the factory nose down rake with no change to the rear suspension. For those customers that require a factory nose down appearance an optional 1” rear block kit is available.

 

Uniball Upper Control Arms are available separately as an upgrade to stock, previously installed Fabtech suspensions or other aftermarket suspension systems.
