Description

The high-pressure fuel injectors in your Power Stroke Diesel engine are designed to precisely control the delivery of diesel fuel into the combustion chamber. But over time, your stock injectors can wear internally leading to improper fuel delivery and poor performance.

The Sinister Diesel remanufactured injectors for the 6.6L Duramax LB7 are stock replacements for your 2001-2004 Chevy or GMC 2500 or 3500HD and returns like-new OEM factory performance and quality without the big OEM replacement price tag. Restore your lost horsepower and torque with a set of remanufactured injectors from Sinister Diesel.
