Important Installation Information

Always verify installed height, valve lift, spring pressure, coil bind clearance, retainer compatibility, base locator compatibility and all other dimensions against the specific engine and cylinder head configuration before installation.

Performance Valve Springs states that it is the installer's responsibility to check and recheck all dimensions, pressures, applications and specifications before, during and after installation. The supplier also states that valve spring pressure specifications have an approximate ±8% tolerance.

Titanium Retainer Note: The supplier manufactures its titanium retainers in-house and advises that delays may occur. The supplier also notes that the majority of its titanium retainers do not fit the OEM spring, so compatibility should be confirmed before installation.
