Product Details

The Supertech Performance GDE-SUEJ6-I is a precision-machined valve guide manufactured from high-quality Magnesium Bronze, a material prized in performance engine building for its superior thermal conductivity, wear resistance, and compatibility with both standard and performance valve stem coatings.

Designed to work in combination with low-friction nitrated valves, these guides deliver an optimized fit that reduces side-loading wear and promotes consistent valve seating — critical for maintaining compression, power output, and long-term engine durability in high-performance and racing applications.

Key Features:

  • Precision-machined from high-quality Magnesium Bronze for superior wear resistance and thermal dissipation
  • Optimized for use with Supertech low-friction nitrated valves for best performance pairing
  • Tight manufacturing tolerances ensure proper valve stem clearance and alignment
  • Suitable for high-performance, forced induction, and motorsport engine builds
  • Direct replacement or performance upgrade over OEM valve guides

Sold individually — per valve guide. Please order the quantity equal to the number of valve guides required for your engine build (e.g., order 16 for a 16-valve engine).

Very easy ordering

Great product, and delivery was on time with no issues. I do recommend.

Some of the parts that I ordered did not match the picture shown. Customer service was helpful and provided return postage. I have returned the parts and order the correct ones.

Great doing business with

Order 12486. Item was simple to find and the website made it very easy to navigate. I appreciated the ability to pay with paypal and email notifications gave me confidence that everything was taken care of properly.

shipment came on time, and was nicely wrapped.

called to ask about fitment. first operator hung up on me after waiting 10 min on hold. called back and hector was able to help me with my order.

Just received my order! I placed the order Sunday night and received it on Tuesday, super fast shipping! The SS vent caps look great and arrived in perfect condition. Thanks!

Autoplicty had the best price by far for a transmission. Fast shipping too!<br>UNFORTUNATELY...FED-EX beat the hell out of it! It was hanging out of the box when it arrived but was not damaged other than a few scrapes. Fed-Ex is not the best way to ship 140lbs...they can't lift it! Oh, and they can't comprehend "this side up" either!

Return customer with a few more future purchases in mind...best price plus quick shipping means these guys are just that good!

Very smooth ordering and processing. Great communications.
