A short fall of the modern day IFS 4wd is the adjustment range provided for successful wheel alignments, this becomes even more of an issue when the vehicle is lifted by more than 1 inch. Not only does the vehicle run into camber and caster issues, but ball joint articulation and clearance issues to the coil over strut at ride and droop height. The new Whiteline adjustable UCA (Upper Control Arm) is an all-in-one solution for any vehicle that has been lifted between 30mm and 70mm. Providing an increase between +0.5 to +3.5 degrees of caster and -1.5 to +1.5 degrees of camber increase (figures quoted are based off an approximate 50mm/ 2 inch) along with greater clearance to the coil over strut and more articulation of the arm by virtue of new maintenance free GIIRO bushing technology.
