Important Installation Information:

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

Performance Valve Springs states that the installer is responsible for checking and rechecking all dimensions, pressures, applications and specifications before, during and after installation. The supplier also specifies an approximate ±8% tolerance on valve spring pressure specifications.

The titanium retainers are manufactured in-house by Performance Valve Springs and availability can be subject to delays. The supplier currently notes a 2–3 week delay on titanium retainers, so availability should be confirmed if the parts are required urgently.
