Description
This soft-rate replacement spring is engineered to work with GFB T9354 and T9360 assemblies, providing a lower spring rate option for fine-tuning valve actuation and boost control characteristics. Offered as a direct-fit GFB part, the soft spring lets tuners and technicians swap spring rates quickly to adjust response without modifying the primary actuator or housing, making it a simple upgrade or service item for compatible boost-control hardware.
