Freeze Plugs

Our D&J Precision Machine Cummins Billet Freeze Plugs are newly designed and they do not leak. This freeze plug design does not require drilling or tapping of the block. It uses an o-ring sealed center bolt and a steel tie-bar to hold the freeze plug in the block. We offer a diverse selection of our freeze plugs with a natural finish or anodized black. You have the option of getting them by the part or in kits that come with 3 side plugs and one front freeze plug. View our wide selection and find the product that’s best for you!
