The XDP LB7 Injector Cup & O-Ring Set XD410 helps hold the fuel injector in the cylinder head of your 2001-2004 GM 6.6L Duramax LB7. The factory injectors cups can often seize to the injector and come out of the head during injector removal. Once the injector and cup are removed, separating them can be a challenge. You'll often need heat, pressure, or force, which can cause you to question whether or not you should re-install the injector cup with your new fuel injector. If you reuse the compromised cup with a new injector it could cause over pressurization of the cooling system leading to symptoms of a blown head gasket, damage to the radiator, water pump, and other cooling system components. In some extreme cases, a catastrophic engine failure can occur if a coolant leak allows for coolant to enter the cylinders of your engine.

Replacing Injector Cups during a fuel injector installation ensures that your engine and fuel injectors maintain proper function and performance. The XD410 Injector Cup Set is made as a direct-fit replacement and comes ready to install with 8 injector cups, and 16 O-rings. Each kit is backed by XDP's 1-year, unlimited mileage warranty. One set required per engine.
