Scott Drake Leaf Spring

Scott Drake Leaf Springs: Restoration Accuracy Meets Real-World Performance

When the rear suspension of a classic Ford Mustang sags after decades of use, not just any replacement will do. Scott Drake has built its reputation on exactly this kind of challenge — producing parts that honor the original factory design while delivering the durability and, when desired, the performance improvements that today's enthusiasts demand. Their leaf spring lineup for the 1964½–1973 Mustang is a prime example of that philosophy in action.

A Range Built for Every Build Goal

One of the defining strengths of the Scott Drake leaf spring catalog is the breadth of options available for a single application. Rather than offering a one-size-fits-all replacement, Scott Drake provides multiple configurations to match the builder's intent:

• 4-Leaf Light Duty (Stock Height): For restorers who want the factory ride height and a close match to original appearance, this is the go-to option. It mirrors the original spring design and keeps the car sitting exactly where Ford intended.
• 4.5-Leaf Mid-Eye: A step up in spring rate that lowers the rear approximately 1 inch for a subtly aggressive stance without sacrificing ride quality.
• 5-Leaf Heavy Duty (Standard Eye): Engineered for added load capacity and a stiffer spring rate, this variant is well-suited to cars that see more spirited driving or carry additional weight.
• 5-Leaf Mid-Eye (High Performance): A performance-oriented spring that lowers the rear roughly 1 inch compared to the standard-eye heavy-duty version, while offering superior road handling over stock 4-leaf designs. This spring also helps prevent wheel hop and spring wrap-up under hard acceleration.
• 5-Leaf Reverse Eye: The most aggressive stance option in the lineup, the reverse-eye configuration lowers the rear ride height by approximately 2 inches while increasing the rear spring rate for less body roll and more responsive cornering.

The Detail That Sets Scott Drake Apart

Beyond the range of configurations, Scott Drake leaf springs stand out for a detail that might seem minor but matters greatly to restoration purists: the finish. Scott Drake springs are painted steel-gray — a deliberate choice to closely replicate the OEM appearance of the original springs rather than defaulting to the flat black that most replacement leaf springs use. For a restorer paying close attention to every undercarriage detail, this distinction is meaningful.

Spring eye bushings are included with the performance variants, allowing for a more complete installation straight out of the box. Scott Drake also offers matching leaf spring shackle kits — available in standard and dual-exhaust configurations with 9/16" rubber bushings and a coordinating steel-gray painted finish — so the entire rear suspension assembly can be refreshed with cohesive, correctly finished hardware.

Fitment You Can Count On

Scott Drake's leaf springs are engineered as direct-fit replacements for 1964½ through 1973 Ford Mustangs, covering both 6-cylinder and V8 applications across the full first-generation run. This wide fitment coverage reflects the same engineering discipline that has made Scott Drake one of the most trusted names in classic Mustang restoration. Whether you're returning a numbers-matching car to stock form or building a weekend driver with a more planted, aggressive rear end, the right spring configuration is here.
