CNC Fabrication Stage 1 Ovate Valve Spring Kit 03-10 Ford 6.0L/6.4L Powerstroke

If you're pushing your Powerstroke beyond stock power levels, factory valve springs can quickly become a weak link. The CNC Fabrication Stage 1 Ovate Valve Spring Kit is designed to provide the additional valve control needed for higher boost, increased RPM, and performance camshaft applications. By keeping the valvetrain stable under demanding conditions, these springs help reduce valve float, improve engine reliability, and give you the confidence to make the most of your build, whether it's a hard-working tow rig or a high-performance street truck. Manufactured from premium ovate wire, these valve springs are engineered to deliver increased spring pressure while minimizing stress concentrations, improving fatigue resistance, and extending service life. The precision-engineered design delivers consistent seat and open pressures to maintain accurate valve control at high cylinder pressures, making them an excellent match for upgraded turbochargers and moderate-performance camshafts. Sold as a complete set for 2003-2010 6.0L and 6.4L Powerstroke engines, this Stage 1 kit is built to provide the durability and reliability serious diesel enthusiasts demand.
