Steeda Mustang Billet Aluminium Vertical Links
Billet-aluminium vertical links reduce rear-suspension deflection under load. CNC-machined bushes work with billet-steel sleeves and spacers for a more controlled connection than the original rubber-bushed links. Steeda reports no additional NVH.
Delrin version 555-4121 targets drag racing, high-power builds and wheel-hop control. Polyurethane version 555-4129 suits street, circuit and autocross use. Installation requires basic hand tools, the necessary hardware is included, and the bushes must be lubricated thoroughly. Made in the USA, with European ECE approval stated by Steeda.
