Valves - One piece forged from a racing grade stainless steel alloy. Our liquid nitriding process creates a valve that is runs cooler, smoother and stronger than traditional O.E.M. or replacement valves. The stems are centerless grinded to a micro finish for a longer life.
Guides - Manganese bronze alloy allows the valve for be fit at a tighter clearance for better heat dissipation, longer life and quieter engine. Special Hi-temp. Viton O'ring to prevent oil infiltration between guide & head. Tapered & radiused nose for better air flow. Unique Super Grip valve seal section. CNC machined
Springs - Manufactured from ultra clean high silicon/vanadium Kobe alloy wire. 1.375" Top retainers for better clearance inside rocker covers. Titanium retainers. All this makes the spring lighter and stronger than anything else out there. By reducing weight in the valvetrain, you can make an engine rev much quicker and make more power.
