Important Installation Information:

Although the PS 3506122 is the same Performance Springs part number for both applications, the installed height and pressure specifications are application-specific.

For the Mitsubishi 6G72 24V DOHC, use the Mitsubishi specifications listed above.

For the Nissan RB26DETT, use the Nissan specifications listed above.

Always verify valve lift, installed height, 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 spring pressure specifications have an approximate ±8% tolerance and that the installer is responsible for checking and rechecking all dimensions, pressures, applications and specifications before, during and after installation.
