Description Overview
One of the most overlooked engine parts when upgrading a turbo in your 7.3L Powerstroke is the valve springs. The added cylinder pressure from upgraded turbos can cause valve float under higher RPM conditions. This can cause a loss of power and overall efficiency issues. The CNC Fabrication Stage 2 Valve Springs are designed for trucks over 500 horsepower and feature a 370lb spring rate and are a great performance upgrade over the stage 1 valve springs. This kit includes new spring retainers and keepers.
