Industrial Injection 11-16 Chevrolet Duramax 6.6L LML Premium Stock Long Block Engine

If your 2011-2016 Chevrolet or GMC truck with the 6.6L Duramax LML engine is in need of a complete rebuild, a stock long block engine is a solid foundation to get you back on the road. This engine assembly from Industrial Injection is built to factory specifications, offering a reliable replacement for your worn-out powerplant. It includes the core components of the engine, ready for you to bolt on your existing accessories and turbocharger.

Industrial Injection takes pride in their engine builds, and this LML long block is no exception. It's assembled with careful attention to detail, ensuring that critical components are properly seated and torqued. The goal is to provide an engine that performs like the original and lasts for many miles to come. This unit is a great option if you're looking for a straightforward replacement without venturing into performance modifications, focusing instead on restoring your truck's original capability.

When installing a long block, remember to transfer all necessary external components from your old engine, such as the fuel system, intake manifold, exhaust manifolds, and accessories. It's also a good practice to replace wear items like the water pump, thermostat, and any seals or gaskets that are easily accessible during the swap. This ensures that your newly installed engine has the best possible start and minimizes the chance of leaks or premature component failure.
