Compatible With 1969-1994 Ford and Mercury V8 applications, it appears across multiple body styles and platforms, including Ford Bronco, Ford E-Series vans, Ford F-Series trucks, Ford Mustang, Mercury Cougar, and Lincoln Continental. The fitment data repeatedly notes that machining may be required, so cylinder head and valvetrain preparation should be verified before installation. This part number 466174 is also associated with performance applications across the Ford and Mercury lineup.\u003c\/p\u003e\u003cp\u003eThis part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat this part helps address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eValve float control in performance engine builds.\u003c\/li\u003e\n\u003cli\u003eInconsistent spring pressure during higher-rpm operation.\u003c\/li\u003e\n\u003cli\u003eValvetrain instability with hydraulic roller camshaft setups.\u003c\/li\u003e\n\u003cli\u003eSpring fitment issues when a specific installed height is required.\u003c\/li\u003e\n\u003cli\u003eReplacement needs for performance-oriented Ford and Mercury engines.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation notes and tips\u003c\/h2\u003e\u003cp\u003eVerify installed height, coil bind clearance, and spring pressure before assembly.
