2011-2016 LML Duramax Exergy Endurance Package

If you have a truck that has aging high mileage parts in need of replacement or have suffered a fuel system failure, this package includes everything you need to help get back on the road again quickly - 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 failure. It includes improved versions of all the major components needed and at a better retail price than GM's CP4 disaster kit.

Core Return: Exergy requires that all cores be returned within 30 days from original purchase of product. If you fail to return the 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.
