This is not a universal all-years kit. Select the exact Duramax engine generation and emissions configuration. Federal- and California-emissions LB7 applications use different passenger-side/EGR arrangements. For 2011–2016 LML applications, verify shock-tower clearance before ordering; the selected configuration may require clearance modification. The raw and ceramic-coated options use the same application-specific component set, with a different manifold finish.

Application and Finish Selection

Select the engine generation and emissions configuration that matches the installed system. Raw and ceramic-coated selections use the same application-specific component set; the selection changes the manifold finish.
