D&J Precision | Cummins Billet Freeze Plug Kit

Introducing our newly designed Cummins Freeze Plugs that do not leak! The newest design of our Billet Freeze Plugs kit do not require drilling and tapping of the block. To hold the freeze plug within the block, we developed a design that uses two bolts that are o-ring sealed while utilizing a steel tie bar. Here is what’s included within our Cummins Billet Freeze Plugs kit includes:

• 3 Side Billet Freeze Plugs
• 1 Front Billet Freeze Plug
• HD O-Rings
• Stainless Hardware
