This is the valve for the 2006 - 2010 Duramax LBZ / LMM engines.  It also works great on the 04-05 LLY engines due to the slightly higher opening PSI.  These valves are known to go bad and open prematurely causing a "fuel rail PSI low" problem.  Once a valve is weakened it tends to get worse.  Replacing the valve with a new one is much safer than shimming it and taking your chances with the high (25,000+ PSI) pressures that this valve was designed to protect from.
