PRESSURE REGULATOR SPRING 4L60
# 37769

PRESSURE REGULATOR SPRING 4L60

Symptoms:

  • Low base line pressure

Cause:
Low spring rates, incorrect spring heights and inappropriate replacements from previous rebuilds.

Correction:
This replacement spring provides a resultant idle base line pressure of 72psi, consistent when compared to the OEM orange spring.


Low spring rates, incorrect spring heights and inappropriate replacements from previous rebuilds can lead to low base line pressure. The Sonnax replacement spring provides a resultant idle base line pressure of 72 psi, and 82-85 psi cracking pressure, which is consistent with the OE orange spring

  • The Sonnax replacement spring is stronger than many alternatives, and allows increased pressures throughout the stroking action of the pressure regulator valve.

Note:
Low line pressure resulting from worn boost valves, a worn pump bore at the pressure regulator valve or pump pocket wear will not be corrected by this spring.
