XDP HD Bolt-On Freeze Plug (Rear) XD339

Don't let a blown freeze plug cause your 2003-2018 Dodge Ram 5.9L/6.7L Diesel to overheat, fix the issue before it happens with the  HD Bolt-On Freeze Plug (Rear) XD339. 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 HD Bolt-On Freeze Plug (Rear) XD339 fastens securely to your engine block 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 1/2" NPT to work with most coolant bypass kits (1/2" NPT plug not included).
