Supertech Performance GDE-NSR7-ET Magnesium Bronze Valve Guide

The Supertech Performance GDE-NSR7-ET valve guide is precision-machined from high-quality Magnesium Bronze, a material prized for its superior thermal conductivity, wear resistance, and self-lubricating properties. Designed for performance and high-mileage durability, these valve guides are an ideal upgrade or direct replacement for worn OEM guides in demanding engine applications.

When paired with low-friction nitrated valves, Supertech valve guides deliver an optimized sealing surface that reduces friction, minimizes valve stem wear, and promotes consistent valve-to-seat alignment — all critical factors in maximizing engine efficiency and longevity.

Key Features:

• Material: Precision-machined Magnesium Bronze for superior wear resistance and thermal performance
• Excellent compatibility with low-friction nitrated valve stems
• Precision tolerances ensure proper valve alignment and sealing
• Ideal for performance builds, engine rebuilds, and high-RPM applications
• Sold individually (per valve guide) — order the quantity matching your engine's valve count (e.g., order 16 for a 16-valve engine)

Supertech Performance is a trusted name in engine component manufacturing, offering race-proven valve train components engineered to meet and exceed OEM standards.
