Supertech Performance GDE-SUEJ6-E Magnesium Bronze Valve Guide Sold Individually

The Supertech Performance GDE-SUEJ6-E is a precision-machined valve guide engineered for high-performance and competition engine applications. Manufactured from high-quality Magnesium Bronze alloy, these guides offer superior thermal conductivity, wear resistance, and dimensional stability compared to standard cast iron or sintered iron OEM guides.

When paired with Supertech's low-friction nitrated valves, the GDE-SUEJ6-E delivers an optimized valve train system that reduces wear, improves heat dissipation, and extends the service life of both the guide and valve stem — making it an ideal upgrade for naturally aspirated, turbocharged, and forced-induction builds.

Key Features:

• Precision-machined from high-quality Magnesium Bronze for superior wear and thermal performance
• Excellent thermal conductivity helps dissipate heat away from the valve stem
• Tight dimensional tolerances ensure proper valve stem clearance and sealing
• Designed to complement Supertech low-friction nitrated valves for a complete valve train solution
• Ideal for performance street, track, and competition engine builds
• Sold individually (per valve guide) — order the exact quantity needed for your application

Supertech Performance valve guides are trusted by professional engine builders worldwide for their consistent quality and performance. Order the correct quantity for your engine — for example, a 16-valve engine will require a quantity of 16.
