Key Features:

  • Military-grade titanium alloy construction for maximum strength-to-weight ratio
  • CNC machined to exacting tolerances for a precise, secure fit
  • Designed for triple groove valve stems with 5.0mm diameter
  • Standard installation height for OEM-style spring seat compatibility
  • Compatible for use with OEM-style S-ring or Supertech SPR-MC56BE valve spring
  • Reduces reciprocating valvetrain mass for improved high-RPM performance and durability
  • Manufactured by Supertech Performance — a trusted name in racing valvetrain components

Seems ok

The best prices on the net.

Order arrived 1 day sooner than expected with correct components. Did get multiple duplicate e-mails confirming order but when I e-mailed customer service to make sure my order was correct and charged appropriately they replied within a few hours. Overall I was pleased with price and service.

Great price on a head gasket. Love the Amazon integration.

Excellent service - thank you!

they had the lowest price around for my car's k&n air filter. A great product at wholesale prices!
