Hello,
STD QSB480 piston #4955622. $165.70 total $994.20
Piston ring set #4955625 $ 48.25 $289.50
I sent my injectors threw TRE Diesel, Tim Barber
The spray pattern will need to be changed for piston.
Tim also did all my engine work. Great guy. He is in Norfolk VA.
Tim is also a cummins dealer, for all your parts.
I live in upstate NY, there is no one here I would trust to do
my work. I have a set of stock injectors That I would sell
if you want a spare set. I also have 2 sets for my truck.
