Eliminate harsh metal-on-metal spring clunks and maintain proper chassis balance with Prothane Red Polyurethane Coil Spring Isolators (Part #6-1703). Engineered specifically for 1983-1999 Ford Mustang and 1983-1986 Mercury Capri models, this pair of high-performance isolators serves as a durable replacement for weak OEM rubber pads that split, rot, and flatten under constant load. The dense, high-durometer red polyurethane formulation resists heavy compression, road contaminants, and environmental decay, ensuring your coil springs remain properly seated and quiet during everyday driving or hard launches.
