A “delete kit” in a 2019 Ram 3500 delete kit is an aftermarket modification package for the 2019 model year Ram 3500 truck. The term “delete” in this context generally means removing or disabling components that are responsible for emissions control.

Purpose of 2019 RAM 3500 delete kit

It is designed to delete or disable specific emissions-related components in the vehicle’s exhaust system.

  1. Achieve improvements in engine performance
  2. Fuel efficiency
  3. Reduce maintenance costs

Common names of the process

This process is commonly referred to as an “EGR delete,” “DPF delete,” or “DEF delete.”

EGR Delete (Exhaust Gas Recirculation): The EGR system recirculates a portion of exhaust gases back into the engine’s intake to reduce nitrogen oxide emissions. However, some truck owners opt for an EGR delete to improve engine performance and reduce carbon buildup on intake valves.

DPF Delete (Diesel Particulate Filter): The DPF is designed to trap and remove particulate matter from the exhaust gases of a diesel engine. Some truck owners choose to remove the DPF to improve exhaust flow and potentially increase engine power. However, DPF deletion is illegal in many regions due to increased emissions.

DEF Delete (Diesel Exhaust Fluid): DEF is used to reduce nitrogen oxide emissions by injecting a urea-based solution into the exhaust stream. Some truck owners consider deleting the DEF system to avoid the need to refill DEF fluid. However, this can result in increased emissions and is also illegal in many places.

Legal, environmental, and mechanical implications

It’s important to note that these modifications can have legal, environmental, and mechanical implications

Legal implications

Deleting emissions-related components is often illegal in many regions due to stricter emissions regulations. Moreover, tampering with emissions systems could void your vehicle’s warranty.

Environmental implications

Emissions control systems are designed to reduce the environmental impact of vehicles. Disabling these systems can lead to increased emissions and air pollution.

Mechanical implications

While some truck owners report improved performance after deleting emissions components, it can also lead to increased wear and tear on the engine and other components. Deleting emissions systems might lead to higher maintenance costs in the long run.

Uses of 2019 RAM 3500 delete kit

A “delete kit” for a 2019 Ram 3500 delete kit is typically used for modifications that involve removing or disabling certain emissions-related components from the vehicle’s exhaust system. Truck owners often do these modifications to achieve specific goals related to performance, fuel efficiency, and maintenance. However, it’s important to note that using a delete kit can have legal, environmental, and mechanical implications, as mentioned in the previous response. Here are some potential reasons why truck owners might consider using a delete kit

Improved performance

Some truck owners believe that removing emissions components can lead to improved engine performance, including increased horsepower and torque. This can be particularly appealing to individuals who use their trucks for heavy towing or hauling.

Enhancement in Exhaust Flow

Deleting components like the diesel particulate filter (DPF) and exhaust gas recirculation (EGR) system can potentially improve exhaust flow, which some enthusiasts believe can lead to better throttle response and overall engine efficiency.

Reduced Maintenance cost

Emissions components like the DPF and selective catalytic reduction (SCR) system require maintenance and occasional replacement. By removing these components, some truck owners hope to reduce maintenance costs and potentially extend the lifespan of their vehicles.

Avoiding Diesel Exhaust Fluid (DEF) Usage

Diesel engines equipped with a DEF system require regular refilling of DEF fluid. Deleting the DEF system would eliminate the need for refills, but it also leads to increased nitrogen oxide emissions and potential legal issues.


Some truck owners enjoy customizing their vehicles to their preferences. Using a delete kit might be seen as a way to modify the truck’s performance characteristics to suit their specific needs.

Cost Savings

While there may be initial costs associated with purchasing and installing a delete kit, some truck owners believe that the long-term savings from reduced maintenance and improved fuel efficiency could outweigh those costs.


It’s important to reiterate that using a delete kit can have serious legal consequences, including fines and penalties, depending on your location and local emissions regulations. Additionally, these modifications can negatively impact air quality and contribute to increased pollution. If you’re considering using a delete kit, it’s strongly recommended to research the legal implications in your area, consult with experts who are knowledgeable about automotive regulations, and carefully weigh the potential benefits against the drawbacks.
