1989-2002 Cummins Rear Freeze Plug Retaining Plate w/o O-Ring (PDM-08208)

Solid billet retaining plate for the rear block freeze plug on 5.9L Cummins engines. Designed for trucks where the factory freeze plug has already started backing out under crankcase pressure — this plate bolts across the back of the block and physically prevents the stock plug from blowing out the rest of the way.

Unlike the O-ring version (PDM-08200), this plate doesn't seal against the bore — it relies on the existing factory freeze plug to retain coolant. The job of this plate is mechanical: keep the stock plug captured. Compatible with all Cummins B-series and 4BT industrial blocks. Use as a quick fix when pulling the engine to replace the plug isn't an option.

• Solid Billet Rear Block Freeze Plug Retainer
• Mechanical Retainer — Retains Existing Stock Plug
• Fits 5.9L 12V, 5.9L 24V, and 4BT Cummins
• Repair Fix When Pulling the Engine Isn't an Option
• Part Number: PDM-08208

• This plate does not seal the freeze plug opening on its own — it captures the existing OE freeze plug behind it. If the stock plug is gone or damaged, replace the plug before bolting this on, or use the O-ring sealing version (PDM-08200) as a complete sealing plug replacement.
• Best used as a preventative fix when the OE plug shows signs of backing out but hasn't blown.
