FULL DESCRIPTION

ProX Steel Intake Valve and Spring Kit

Upgrade your engine's performance and durability with the ProX Steel Intake Valve and Spring Kit. This kit offers a robust alternative to standard titanium valves, providing significantly extended lifespan. ProX steel valves are designed to last up to three times longer than OEM titanium valves.

Each kit includes a set of high-quality steel intake valves and specially engineered, stronger valve springs. These heavier springs are necessary to accommodate the increased weight of the steel valves, ensuring optimal performance and reliability.

This ProX kit is designed for a direct replacement of your original equipment (OEM) valves and valve springs. You can utilize your existing OEM retainers, bases, and valve seats during installation.

Key Features:

  • Extended lifespan compared to OEM titanium valves
  • Constructed with durable steel for longevity
  • Includes stronger valve springs to match valve weight
  • Direct replacement for OEM valves and springs
  • Compatible with OEM retainers, bases, and valve seats
