Whiteline adjustable rear upper control arm for 2005-2010 Ford Mustang (S197) replaces the ultra-compliant stock arm with a 4130 Chromalloy construction and a synthetic elastomer bushing to increase rear stability and reduce brake hop. The longer arm length mirrors Ford's later revision to reduce axle tramp; an eccentric crush tube allows pinion angle and instant center adjustment without weakening the arm. Protective plating and powder coating resist corrosion, and an install guide is included.
