What is an L5P Delete Kit?

The L5P delete kit is an all-in-one performance package designed for 2017–2023 GM Duramax L5P engines.

For those with other Duramax engines, this collection also includes kits for the LM2 and LML models, ensuring every GM Duramax diesel owner has access to the perfect delete kit for their truck.


Benefits of an L5P Delete Kit

An L5P delete kit provides significant improvements in several key areas:

  • Enhanced Fuel Efficiency: Increased mileage, especially for long-haul driving and towing applications.

  • Boosted Performance: Gains in horsepower and torque for heavy-duty applications.

  • Reduced Engine Strain: With the removal of failure-prone emissions systems, the engine operates more smoothly and reliably.

  • Longer Engine Life: By removing parts that are prone to clogging and failure, you extend the longevity of your L5P Duramax engine.

These benefits make the L5P delete kit one of the most popular performance upgrades for truck enthusiasts and commercial drivers.
