04.5-10 6.6L & 07.5-16 6.7L Common Rail Stainless Race Valve

This is a stainless steel plug to replace the factory pressure relief valve on 2004.5 to 2012 LLY, LBZ, & LMM Duramax engines and 2007.5-2016 Dodge Ram Cummins 6.7L engines.  This is for race applications only!  There is no safety factor in the event of a spike of fuel pressure happening in the common rail.

A new o-ring is recommended.
