Product Type Freeze Plug

Hard acceleration, increased engine RPM, and temperature differences in your cooling system can cause the rear freeze plug to blow out. Not only can a blown out freeze plug leave you stranded, it also causes large coolant losses that lead to overheating conditions.

The XD339 Bolt-On Rear Freeze Plug fastens securely to your cylinder head using existing bolt holes. Each freeze plug is machined from 6061 aluminum and features a built-in o-ring for a leak-free seal.

This freeze plug does not require transmission removal for installation and is pre-drilled and tapped to 3/4" NPT to work with most coolant bypass kits (3/4" NPT plug not included).


  • Eliminates Risk Of Blown Freeze Plugs
  • O-Ring Gasket Seal
  • CNC-Machined 6061 Aluminum Construction
