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.\n\nEach ProX kit includes a set of high-quality steel intake valves along with specially engineered, stronger valve springs.
