Description
The Heidts 4-Link Rear Suspension Kit for the 1964–1970 Ford Mustang is a premier bolt-on upgrade designed to replace the factory leaf springs. This system provides modern axle control, significantly improved traction, and the adjustability required for high-performance street and Pro-Touring builds.
Performance and Adjustability
Complete Bolt-On Design: Engineered specifically for the Mustang chassis, this kit requires no cutting or floor modifications. It allows for a total suspension transformation while preserving the car's original unibody structure.
Precision Tuning: The kit features adjustable 4-link mounts, giving you the ability to fine-tune the "instant center" and anti-squat settings. This is crucial for optimizing tire "hook" during acceleration and stability through corners.
Lateral Control: To ensure the rear axle remains perfectly centered, the system includes a panhard bar with dedicated chassis and axle brackets, eliminating the lateral "walk" common with leaf spring setups.
Modern Dampening: Equipped with adjustable billet coil-over shocks, providing full control over ride height and stiffness to achieve the perfect stance and feel.
Structural Integrity and Aesthetics
Coil-Over Crossmember: The kit includes a full upper coil-over crossmember that reinforces the rear frame section, providing a rigid mounting point for the suspension and improving overall chassis stiffness.
Link Customization: The 4-bar links are available in plain for a clean, factory-plus look or polished for show-quality builds.
Shock Finishes: Billet aluminum shocks come in Black, Plain, or Polished finishes to match your project's aesthetic goals.
Kit Includes:
Four Link Bars: Adjustable 4-bar links (Plain or Polished).
Crossmember: Full upper bolt-in coil-over mounting crossmember.
Brackets: Complete set of chassis and axle mounting brackets.
Panhard Bar: Lateral stabilization bar with all necessary hardware.
Suspension: Adjustable billet coil-over shocks and 10-inch performance springs.
Full Rear End Package: Optional rear axle housings with pre-installed brackets, high-strength axles, and Positraction gear sets.
Chassis Strengthening: Optional Subframe Connectors and Chassis Stiffeners are highly recommended to minimize unibody flex in high-horsepower Mustangs.
Stabilization: A rear sway bar to further reduce body roll.
Technical Notes
Compatibility: This kit is designed to work as a standalone rear upgrade or in perfect synergy with a Heidts front IFS system for a complete chassis modernization.
Axle Housing: While the kit can be used with an original housing (requires bracket welding), the optional pre-bracketed housing offers a true bolt-in experience.
