Description

The Steeda S550/S650 Mustang Billet Aluminum Vertical Links are engineered to provide superior handling characteristics for performance driving, including street use, road racing, and autocross. Utilizing polyurethane bushings, these links significantly reduce deflection compared to stock rubber bushings, ensuring improved control through jounce and rebound without introducing any additional NVH. Crafted from a single piece of 6061 aircraft-grade aluminum, the one-piece billet design is manufactured to an accuracy of 0.001 inches. This precision is critical for maintaining the correct geometry of the S550/S650 Mustang's suspension, as slight variations in length from a welded design could severely compromise handling and stability. The combination of larger polyurethane bushings with billet steel sleeves and spacers offers enhanced control while preventing suspension bind or artificial spring rate additions. These vertical links are particularly beneficial for road racers, providing greater stability during hard braking at high speeds. They are proudly made in the USA and come with a limited lifetime warranty. This product is recommended for handling applications. Note: These vertical links fit Non-Brembo Package (single piston rear caliper) 2024+ Mustang models. For Performance Pack or Brembo Package 2024+ Mustangs, part number 555-4130 is required.
