Product Details

Manley 11427TB-8 titanium valves feature forged one-piece construction with grain flow, providing superior strength and durability for high-performance and racing applications. These titanium exhaust valves weigh just 76 grams each and are designed to reduce overall valvetrain mass for improved throttle response and higher RPM potential.

Key Specifications:

  • 1.600-inch head diameter with .3415-inch stem diameter
  • .200 inches longer than stock height
  • Inserted hard tips for extended durability
  • Bead Loc single radius keeper groove
  • Micro-polished jewel-like surface finish

Features and Benefits:

  • Premium titanium alloys provide the best balance of mechanical properties, hardness, ductility, and fatigue strength
  • Micro-polish process eliminates potential stress risers and increases fatigue strength
  • Machined in state-of-the-art CNC turning centers and valve stem grinders to exacting tolerances
  • Reduced valvetrain mass allows for quicker valve action and increased throttle response
  • High temperature material with higher hardness for extreme racing conditions

Designed for use with All Pro, Brodix ASCS and GB Heads, and M&M Revolution cylinder heads. These valves are ideal for drag racing, road racing, and high-performance applications where reduced weight and maximum durability are essential.
