Supertech Performance GDE-HB55-E Magnesium Bronze Valve Guide

The Supertech Performance GDE-HB55-E Valve Guide is precision-machined from high-quality Magnesium Bronze — a material renowned for its superior thermal conductivity, wear resistance, and self-lubricating properties compared to standard cast iron guides. Designed for high-performance and racing applications, these guides deliver consistent valve alignment and extended service life under extreme heat and RPM conditions.

When paired with low-friction nitrated valves, Supertech valve guides provide an optimized interface that reduces heat buildup and wear at the valve stem, making them an excellent upgrade for both naturally aspirated and forced-induction performance engines.

Key Features:

• Precision-machined from high-quality Magnesium Bronze for superior wear resistance and heat dissipation
• Compatible with low-friction nitrated valves for maximum performance and durability
• Tight manufacturing tolerances ensure proper valve alignment and sealing
• Ideal for street performance, track, and racing engine builds
• Sold individually — per valve guide; order the quantity matching your engine's total valve count

These guides are sold one (1) per order quantity. For example, if your engine requires 16 valve guides, add a quantity of 16 to your cart.
