Del West 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 Aluminium
- Aluminium 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.
