KMS manufactures most of their products in house. Retainers (titanium & aluminum), bronze valve guides, aluminum block guards, and block girdles are just a few of the performance parts KMS manufactures in house and can be custom created or modified to work with almost any application.
Looking to reduce the weight of your Honda or Acura's internals? If so, then our aluminum retainers will help put that engine on a diet to achieve maximum horse power and performance.
