Product Details

The Supertech Performance GDE-NSR6-ET is a precision-machined valve guide crafted from high-quality Magnesium Bronze — a material chosen for its superior thermal conductivity, wear resistance, and dimensional stability under high-heat, high-RPM conditions. Designed to work seamlessly with Supertech's line of nitrated performance valves, these guides help reduce friction and extend the service life of the valvetrain.

Key Features:

  • Precision-machined from high-quality Magnesium Bronze for superior durability and heat dissipation
  • Optimized for use with low-friction nitrated valves for maximum performance synergy
  • Tight dimensional tolerances support consistent valve seating and reduced side-loading
  • Ideal for performance, racing, and high-mileage rebuild applications
  • Sold individually — order the exact quantity needed for your application (e.g., order 16 for a 16-valve engine)

Supertech Performance is a trusted name in high-performance valvetrain components, supplying professional engine builders and motorsport teams worldwide. The GDE-NSR6-ET valve guide is an excellent choice for engine builders seeking OEM-quality fit with aftermarket performance characteristics.
