2007.5-2010 LMM Duramax Performance Parts & Upgrades

Optimize the power, towing capability, and overall driving manners of your GM diesel with premium 2007.5–2010 LMM Duramax performance parts from Full Force Diesel. Marking the first major shift into modern emissions standards, the 6.6L LMM Duramax retained the robust mechanical engine architecture of its predecessors while introducing factory diesel particulate filters (DPF). Whether you are looking to maximize your truck's efficiency under heavy towing loads, run a clean and reliable daily driver, or upgrade key weak points, we carry the specialized components to get the job done right.

Essential Fuel System Protection & Upgrades

Just like earlier generations of the 6.6L engine, the LMM Duramax relies on the high-performance Bosch CP3 injection pump but lacks a factory-installed fuel lift pump. To safeguard your expensive common-rail fuel system from the issues of fuel starvation, water intrusion, and fine particulate wear, installing an aftermarket FASS or AirDog fuel-air separation system is highly recommended. These frame-mounted lift pumps maintain positive fuel pressure to your CP3, extending injector life and improving engine efficiency. Pair this protection with performance fuel injectors and advanced custom programmers to maximize clean combustion and overall power output.

Maximizing Airflow & Reducing Exhaust Heat

Because the factory emissions equipment on the LMM can increase under-hood heat, improving engine breathing is critical for reducing exhaust gas temperatures (EGTs). Upgrading to a smooth, mandrel-bent aftermarket turbo downpipe removes the major restriction directly behind the turbocharger. Combine your new downpipe with a high-flow cold air intake system and an upgraded intercooler pipe kit to increase cold air density going into the engine. Because the LMM easily responds to tuning with massive torque gains, we also recommend upgrading your Allison 6-speed transmission with heavy-duty oil coolers, deep pans, or robust torque converters to ensure your drivetrain is ready for heavy work.

At Full Force Diesel, we carry a complete selection of premium components engineered specifically for your 2007.5-2010 GM truck. Browse the full subcategory directory below to find exactly what your Silverado or Sierra needs.
