What's the difference between a DPF delete and a full delete?

A DPF delete removes only the diesel particulate filter. A full delete removes both the DPF and the EGR (exhaust gas recirculation) cooler and valve. Full deletes give you more performance gain because you're eliminating two restriction points instead of one. Most guys go full delete if they're already committed to the mod.

Do I need tuning software with a delete kit?

Yes. A delete kit removes the hardware, but tuning software recalibrates your engine computer to run properly without those emissions systems. Without tuning, your truck will throw codes and run rough. That's why tuner harness kits and software go hand-in-hand.

Which kit fits my 2018 Ram Cummins?

The Ram Cummins 6.7 Full Delete Bundle | 2013-2018 is your match. Make sure you grab the 2013-2018 version, not the 2019-2021, because the mounting points changed in the newer generation.

Will a delete kit damage my engine?

No. A properly installed delete kit actually improves engine longevity by reducing heat and backpressure. The emissions systems (DPF and EGR) trap soot and recirculate hot exhaust, which stresses your engine. Removing them lets your 6.7L or LML run cooler and cleaner.

Can I install this myself?

Full delete kits require mechanical skill and the right tools. You'll need to remove exhaust components, disconnect sensors, and install new piping. If you're comfortable with wrench work, you can do it in your driveway. Otherwise, have a diesel shop handle installation. Factor in 6-8 hours of labor.

What about DEF (diesel exhaust fluid) after a delete?

You won't need DEF after a full delete because the SCR (selective catalytic reduction) system that uses DEF gets removed along with the rest of your emissions gear. One less fluid to buy and one less tank to monitor.

Emissions deletes are illegal for street use in most states and federally regulated for on-road vehicles. These kits are sold for off-road and competition use only. Check your local laws before purchasing or installing.
