LB7 2001-2004 GM Duramax 2500 Diesel 6.6L Injector Return Line Bolt at the INJECTOR - HEAVY DUTY Design - Pack of 8 (1 truck)

Description

With the shallow head on the stock bolt, it is common for the head to round out during removal. This HEAVY DUTY Bolt has been redesigned to allow nearly double the tool engagement. Proper engagement of the Allen wrench is crucial for accurate torque during reassembly to avoid a fuel leak at the return line fitting. The unique head shape offers the needed strength while maintaining proper clearance on other engine components.
