Common Ordering Mistakes

• Ordering this kit for a Ram 2500 or 3500 pickup truck instead of a cab and chassis model.
• Selecting the wrong model-year option, such as 2013-2018 for a 2019-2024 truck.
• Selecting the non-heater option when the fuel-heater version is needed, or the reverse.

Final Fit Check

• Confirm your truck is a cab and chassis model, not a 2500 or 3500 pickup.
• Confirm your Ram has a rear-frame cab and chassis build or a 52-gallon-or-larger fuel tank.
• Select your model year in the options: 2013-2018 or 2019-2024.
• Select the fuel-heater or non-heater option to match your build.

Once your model year, heater preference, and vehicle configuration are selected in the options, the G&R Diesel Rear Cat Conversion Kit provides the matching single filter head for the listed rear-frame cab and chassis and 52-gallon-plus tank applications.
