  • For high-performance street/track cars or turbo/supercharges engines we recommend Steel Alloy retainers for increased longevity.
  • For Full-Race Engines that require a lighter weight valvetrain we recommend Titanium retainers.
  • As with all titanium retainers we strongly recommend the valvetrain is regularly inspected.
