    SKU: KTA416 Benefit Note:Complete replacement control arms featuring offset bushings that are primarily designed to improve traction and cornering grip under power. Increasing static caster to both front wheels. The special low compliance bushings reduce caster wind-back and maintain tighter tolerances between static and dynamic alignment settings. The additional caster coupled with the firmer bushings serve to dramatically sharpen initial turn-in response - forcing more consistent alignment angles through the corner due to the reduced bush compliance.

    With performance permanently ingrained in mind, these Whiteline high performance, vertical links are designed from high performance 6061-T6 forged aviation grade aluminium. The design is built with a sturdy and robust I beam design, which completely eliminates all the undesirable effects caused by the high compliant rubber bushings and OEM, low cost, pressed steel design linkage. Utilizing a CNC precision machined forging, gives you the peace of mind that the vertical link mounting length has been maintained and the suspension geometry remains consistent and true the way it was intended. Installed with minimal flex polymer, grease free bushings, removes the nasty undesirable effects of rubber bushing oscillations under high loading, maintaining consistent alignment angles during cornering and eliminating wheel hop. The Whiteline vertical link is a must have item for the Mustang if suspension performance is paramount.
