CNC Fabrication Stage 1 Valve Spring Set 94-03 Ford 7.3L Powerstroke
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 1 Valve Springs are designed for trucks up to 500 horsepower and feature a 119lb seat load and are a great mild upgrade over the stock valve springs.

How it works

Your privacy
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.
