• Exhaust Systems for 2011 to 2016 Duramax:

  Replacing your stock exhaust with a high-flow system improves airflow, reduces backpressure, and lowers EGTs (Exhaust Gas Temperatures), resulting in more efficient engine operation and an increase in horsepower.

• Cold Air Intake Systems for LML Duramax:

  Installing a cold air intake allows your engine to pull in cooler, denser air, which helps with combustion and leads to gains in both power and fuel efficiency. This upgrade can have a noticeable impact on the performance of your 2011 - 2016 LML Duramax.

• Fuel Injector Upgrades for LML Duramax:

  Over time, stock injectors can lose their edge. Upgrading to high-performance injectors helps ensure optimal fuel delivery, restoring lost horsepower and improving overall fuel economy in your LML Duramax.

• Suspension Upgrades for 2011 to 2016 Duramax Trucks:

  Whether you’re towing heavy loads or taking your truck off-road, suspension upgrades help improve ride quality, handling, and stability. For the 2011 - 2016 LML Duramax, a suspension upgrade can make a noticeable difference in comfort and performance.
