The ST Muscle Car rear springs are heavy-duty, stock-height replacement coils for the Mustang and Capri, matched to the factory dampers to restore proper ride height while firming up body control. They are cold-wound from high-strength chrome silicon steel, multi-tempered, and finished with an epoxy coating for corrosion resistance. The high-strength steel keeps the springs block resistant so they resist sag and hold their height over time.
