FAQ
Will this fit all 2001–2016 Duramax engines?
Yes. It covers LB7, LLY, LBZ, LMM, and LML 6.6L Duramax applications.
Is this the gasket at the turbo inlet or the manifold side?
This is the turbo inlet (up-pipe to turbo) gasket. For the manifold-to-up-pipe side, the common OE reference is GM 97188685.
Do I need two gaskets?
Each turbo inlet uses one gasket per up-pipe flange. Many techs replace both sides and related manifold-to-up-pipe gaskets during service.
Any installation tips?
Inspect mating surfaces for warpage, clean thoroughly, and torque fasteners to factory spec after heat-cycle recheck.
