2011-2016 LML Duramax Exergy LML Endurance Package - E12 10502

This package includes the Exergy Long Life LML Injectors, our LML Improved Stock CP4.2 (equipped with larger diameter rollers, pinned followers, and the Exergy Fuel System saver), as well as replacement left and right-hand fuel rails, all for an affordable retail price of $3,950. This is an excellent option for customers needing to replace their fuel system after a CP4.2 failure. It includes improved versions of all the major components needed, at a retail price cheaper than GM's kit.

Core Return: Exergy requires that all injector cores be returned within 30 days from original purchase of product. If you fail to return the injector core(s) within 30 days, you will be charged in full for the core(s) ($150 per injector). Cores that have missing and/or damaged component(s) will not receive credit. To avoid this, please package your cores well in an organized fashion with the Injector Process Form inserted (see examples and find Injector Process Form on the shipping and returns page). If you have an outstanding circumstance, please contact us.
