About Xceldyne Spring Retainer

Xceldyne Spring Retainer

  • Lightweight CNC-machined titanium retainers greatly reduce valvetrain mass and increase engine RPM
  • Increases valve spring life over heavier, stock steel retainers
  • Use in conjunction with most stock springs and all of CV4s racing valve springs
  • When used with Xceldyne machined valve locks, you have a perfect retainer/lock/stem fit for unprecedented high-rpm valvetrain control.
