64-73 Mustang Rr Spring Bushings Black

The 64-73 Mustang Rr Spring Bushings Black from Energy Suspension are engineered polyurethane leaf spring bushing replacements designed for the rear suspension of first and second-generation Ford Mustangs (1964–1973). These bushings address a common wear point in classic Mustang suspension systems where original rubber deteriorates, causing excessive movement, clunking noises, and compromised handling. Whether you're restoring a vintage muscle car or tightening up an aging street machine, upgrading to polyurethane rear spring bushings is one of the most effective ways to restore suspension rigidity and improve steering response without a full frame-off rebuild.

Energy Suspension's Hyper-Flex polyurethane formulation offers superior durability compared to stock rubber components, resisting ozone, UV, and thermal degradation for decades of service life. The black polyurethane material bonds to cadmium-plated steel sleeves, creating a solid bushing assembly that maintains consistent spring preload and ride height under cornering and braking loads. Unlike brittle rubber bushings that compress and crack with age, polyurethane stays firm across temperature swings while allowing controlled articulation—this translates to less axle wrap, reduced body roll, and more predictable suspension geometry during acceleration and hard cornering. The kit includes all bushings needed for complete rear leaf spring replacement, simplifying the installation process for both restoration shops and home mechanics.

Bolt-in installation on your 1964–1973 Ford Mustang requires no cutting, welding, or frame modifications—simply remove the old rubber bushings and press or install the new polyurethane units onto existing spring eyes and frame mounts. Mechanics and restoration specialists frequently specify Energy Suspension bushings for Mustangs being prepped for show, autocross, or spirited street duty because they preserve original suspension geometry while eliminating the slop and noise that plagues aged vehicles. The compact dimensions (6.4 x 3.2 x 6.8 inches) and lightweight construction (2.15 lbs) ensure straightforward handling and fitment on any first or second-generation Mustang platform without additional bracing or reinforcement.
