OE-Style Fit for Classic Ford and Mercury

Common Problems It Can Address

• Clunking or rattling from the front suspension
• Excessive stabilizer bar movement at the frame mount
• Worn, cracked, or compressed original bushings
• Loose-feeling front-end handling caused by degraded sway bar support
• Noise during cornering or over uneven pavement

Installation Notes and Tips

Verify bar diameter and mounting location before installation. This kit does not include mounting hardware, so reuse or source the required fasteners as needed. Clean the mounting surfaces and inspect the stabilizer bar and brackets for wear before installing the new bushings. Confirm fitment against the vehicle’s suspension configuration for 1964-1973 Ford Mustang or 1967-1973 Mercury Cougar front-to-frame applications.
