The Supertech dual valve spring kit for Toyota 4A-GE 16-valve engines supplies matched dual springs made to fit the 4A-GE head. Intended as a direct replacement during head rebuilds or valve-train refreshes, the kit restores correct spring rates and valve return behavior to help maintain consistent valve seating across all cylinders in routine service or upgraded assemblies.
