Spring Retainers

All Del West valve guides are manufactured with the necessary tolerances and high quality level so that they can be installed directly into the cylinder head guide bore without additional work.

We manufacture spring retainers for all types of racing engines in the following materials:

  • Aerospace quality titanium
  • 7000 Series Aluminum
  • Aluminum Metal Matrix Composite
  • Maraging steel- C300

Each material is matched with an appropriate heat treatment and/or surface treatment to maximize the wear resistance and life of the retainer. All Del West retainers undergo 100% quality control for all critical characteristics. Since the fit of a retainer to the appropriate keeper (lock) is critical, we strongly recommend that they be mated to a Del West manufactured keeper.

Please speak with a Del West engineer to understand what is right for your application.

Del West. Precisely.
