Description
The 1955–1956 Mercury Car Rear SuperSlide Multi-Leaf Springs (Pair) by Posies provides a targeted rear suspension solution for mid-fifties Mercury passenger cars (Sedan, Coupe, Hardtop, Convertible). Engineered as direct bolt-in replacements for fatigued factory leaf packs, these springs install directly into original frame hangers and shackle mounts without cutting or chassis modification.
Constructed from high-tensile tempered spring steel, each spring features Posies' signature SuperSlide moly-nylon inter-leaf buttons to eliminate metal-to-metal friction, squeaks, and binding.
