KIBBLEWHITE - 30-30753 - Black Diamond™ Engine Valve - '04-'05 Honda Sportrax, TRX450R
Replacing worn valves on '04-'05 Honda? The Kibblewhite Black Diamond (30-30753) is CNC machined from a single EV8 stainless steel forging, engineered in FEA software and flow-bench tested for airflow that keeps power on tap. A German-process hardening treatment and black nitride-coated stem give it wear and corrosion resistance that outperforms standard plating methods, so the new valve isn't the first thing to wear out again. Made in the USA.
Features
- Black Diamond™ valves are CNC machined from one-piece forgings of EV8 Stainless Steel
- Lightweight, strong, one piece forging with profiles that provide excellent flow characteristics
- Valve is infused by a special German process to a depth of .002, with a surface build up of .0002 which improves wear properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and nickel electrolysis plating
- Each valve is designed using Finite Element Analysis (F.E.A) software, and profiles are tested on a computerized flow bench
- Stems are coated with black nitroneg
- Made in the USA
