Collection: 2013-2018 Cummins 6.7L

This collection is built for 2013–2018 Dodge Ram Cummins 6.7L owners who don’t waste time chasing parts that might work. You’re here because you need tuning kits and diesel components that are tested, matched, and made for real trucks that actually work.

From 2013 through 2018, these Cummins platforms went through updates—but the tuning needs stayed the same: more control, better response, and reliable fitment. That’s why every kit in this collection includes only what makes sense—DIESELR custom files, proven hardware, and parts that install clean without hacking things together.

We carry blank and preloaded tuners like the GDP Commander, EZ Lynk AutoAgent, and SCT X4, all compatible with tuning files tailored for towing, daily driving, and work use. Pair your tuner with a full All-In-One Kit and you’re ready to go—no guesswork, no fluff.

Expect:

• SOTF switch kits and harnesses for trucks with compatible control
• Exhaust and EGR components built for your generation Cummins
• Matched tuning files that deliver smoother drivability and real power
• Tuning support from people who actually know what they're doing

Whether you drive a 2014 Ram 2500 or a 2018 3500 dually, these kits are for owners who work their trucks, not park them pretty. If you want to do it once and do it right, you’re in the right place.

This is Dieselr. Tuning first. No B.S. Just results.
