Product Details

These valves feature a +1mm oversize design with a 36mm head diameter to improve airflow and engine breathing for increased power output.

Key Features:

  • One-piece forged stainless steel 21-4N construction for maximum strength and durability
  • Black nitrided finish with 800HV minimum microhardness for superior wear resistance
  • +1mm oversized 36mm dished valve head for improved flow characteristics
  • 5.48mm stem diameter with single groove design
  • 108.85mm overall valve length
  • Smoother surface finish than chrome-plated valves for reduced friction
  • Special heat treatment process optimized for performance applications

Supertech valves are engineered in Silicon Valley with over 30 years of experience in motorsport valve train technology. The black nitriding process creates a hard surface layer while maintaining ductility underneath, making these valves ideal for high-RPM racing applications including drag racing, road racing, and rally competition.

Great price

Great in stock items and very fast delivery. Wish website had little more description of item while doing research and price was not cheapest, but cheapest warehouse was out.

Great customer service however the merchandise I ordered was damaged which was a great inconvenience ☹️.

Other variations of the control arms were not shown to me on the website.
