What delete kit options are available for the 2017-2022 Duramax L5P?

We carry full delete bundles for the L5P that cover EGR delete, DPF delete, and DEF/SCR delete. You can also buy individual components. The L5P uses a more complex emissions system than earlier Duramax engines, so a full bundle is the most popular choice for serious builds.

Do I need a custom tune when deleting the L5P Duramax?

Yes, a custom tune is required for the L5P delete. The factory ECM monitors emissions components and will throw codes and enter limp mode without proper tuning. We recommend pairing any delete kit with a quality L5P-specific tuner to get the full benefit and eliminate warning lights.

Will deleting the L5P void my GM factory warranty?

Yes. Any modification to emissions control systems voids the factory powertrain warranty. These kits are designed for off-road and competition use only. Always verify your local and state regulations before purchasing or installing any delete components.

How much power can I gain with an L5P delete and tune?

Most L5P owners see gains of 60-100+ horsepower and significant torque increases after a full delete paired with aggressive tuning. The L5P already makes strong stock numbers, but cleaning up the intake and eliminating parasitic emissions loads unlocks real performance gains.

Is the L5P delete installation something I can do at home?

Mechanically experienced owners can complete the installation, but it's more involved than older Duramax generations. Plan for a full day in the shop. The L5P requires intake manifold access and careful handling of coolant lines. A service manual is strongly recommended.

What is your return policy on L5P delete kits?

We accept returns on uninstalled, unused parts within 30 days of delivery. Once a kit has been installed or shows signs of use, it is non-returnable. Contact our support team before returning to get an RMA number and instructions.

Do you offer free shipping on L5P delete bundles?

Yes, we offer free shipping on qualifying orders within the continental United States. Most full delete bundles exceed the free shipping threshold. Orders typically ship within 1-2 business days and arrive within 5-7 business days via ground freight.
