Upgrade your 1964–1966 Mustang with the Street Kit, engineered for big block 429–460 BBF builds that demand a firmer, 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.

The Street Kit includes a Universal Mount K-Member, 429–460 BBF engine mounts, bushing A-arms, spindle struts with a 175 lb spring rate, and a manual Fox steering rack. The stiffer 175 lb springs reduce body roll and enhance front-end control, giving your Mustang a more aggressive, planted stance. The manual Fox rack provides direct, precise steering for a true driver-focused experience and excellent feedback on every turn.

This kit provides a solid suspension foundation for big block swaps while keeping your Mustang street-ready and fun to drive.
