Compatibility / Fitment:

Fits 2001–2004.5 GM 6.6L Duramax LB7 engines (VIN code 1) in the Chevrolet Silverado and GMC Sierra 2500HD and 3500HD, and Chevrolet Kodiak and GMC TopKick 4500 and 5500.

Hard fitment gate — LB7 only: This injector fits the LB7 Duramax, identified by VIN code 1 (the 8th digit of the VIN). The 2004.5–2005 LLY (VIN code 2) and later Duramax engines use different injectors. Confirm the VIN code before ordering.

Installation note: LB7 injectors are located under the valve covers, so replacement is a larger job than on later Duramax engines. Use the supplied gasket and O-rings, replace the fuel filter, and use clean fuel. Clean the injector bore and seat, and don't over-torque the injector hold-down or electrical connections. Follow GM's torque specifications.

Quantity note: This listing is for one injector. The LB7 uses eight. Because of the labor involved, many owners replace all eight at once.
