About this product
About this product
Upgrade your engine's performance and durability with the Prox Steel Valve and Spring Kit. This kit provides a complete solution for replacing your OEM valves and valve springs, ensuring optimal performance under even the most demanding conditions.
Description
The Prox Valve and Spring Kit features steel, nitrided valves that offer superior durability and reduced wear compared to OEM components. The nitriding process hardens the valve surface, making them exceptionally resistant to wear and tear. Stronger valve springs are included to effectively manage the increased weight of the steel valves, preventing valve float and maintaining precise valve control at high RPMs. These springs are constructed from premium chrome vanadium steel, ensuring exceptional performance and long-lasting durability. The kit is designed for easy installation, utilizing OEM retainers, bases, and valve seals for a seamless fit.
