FULL DESCRIPTION
ProX Steel Intake Valve and Spring Kit
This ProX Steel Intake Valve and Spring Kit is designed to replace your original equipment (OEM) titanium valves and springs. ProX offers a comprehensive selection of titanium-to-steel conversion kits that provide significantly extended longevity compared to standard OEM titanium valves, often lasting up to three times longer.
Each ProX kit includes a set of high-quality steel intake valves along with specially engineered, stronger valve springs. The increased weight of steel valves necessitates the use of a heavier valve spring for optimal performance and durability. This kit is designed for a direct replacement of your OEM valves and springs, allowing you to utilize your existing OEM retainers, bases, and valve seats during installation.
Key Features:
- Includes steel intake valves and stronger valve springs.
- Offers up to three times the lifespan of OEM titanium valves.
- Direct replacement for OEM valves and springs.
- Utilizes existing OEM retainers, bases, and valve seats.
- Engineered for enhanced durability and performance.
