SBI diesel performance valves are a bimetallic design utilizing special processes which improve their overall durability and performance over stock valves.

Each valve is constructed using a premium-grade austenitic stainless steel head material on both the intake ( EV8 ) and exhaust ( EV16 ) with a mid-stem weld using a high-grade chromium steel stem material ( HNV3 ). Each valve is fully machined and nitrided all over, then polished. Each valve tip is hardened to a minimum of 50 HRc for added durability.

  • Premium-grade austenitic stainless steel head material on both intake and exhaust.
