CNC Fabrication Stage 1 Valve Spring Set 94-03 Ford 7.3L Powerstroke
Description
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.

About WrenchConnected
WrenchConnected is an independent installation marketplace operating in partnership with Diesel Power Products.
How it works
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
Pricing
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
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.
