Upgrade your 1964–1966 Mustang with the Street Kit, engineered for big block 429–460 BBF builds that demand a firm, performance-focused ride with sharper handling and improved cornering. This kit combines classic Mustang style with modern suspension technology to deliver a planted, responsive driving experience that’s perfect for spirited street driving.
The Street Kit includes a Universal Mount K-Member, 429–460 BBF engine mounts, bushing A-arms, spindle struts with a 200 lb spring rate, and a manual Fox steering rack. The stiffer 200 lb springs reduce body roll, improve front-end control, and provide a more aggressive, planted stance. The manual Fox rack ensures direct, responsive steering for a true driver-focused feel and precise handling around every corner.
This kit provides a solid suspension foundation for big block swaps while keeping your Mustang street-ready and performance-capable.
