Attention:
If you have a GM Duramax  please verify your engine type
before ordering any product. You will either have an LB7, LLY, or LBZ  motor, many of the products we offer are not interchangeable with all three engines.

To Verify: Check the 8th digit in the VIN number,
                If it's a 1 you have the LB7 motor and it is covered by the model years 01-04
                If it's a 2 you have the LLY motor and it is covered by the model years 04.5-05

Products in this section are designed to work on 2004.5 and 2005 6.6L GM Duramax equipped trucks unless otherwise noted.
