Built by Diesel. Driven by Work.

TrueAmericanDiesel was created by people who depend on their trucks to make a living. We were tired of emission failures, overpriced dealer parts, and solutions that didn’t last. So we built high-quality delete kits and performance parts with custom tuning made for real trucks and real workloads — backed by real support from people who know diesel inside and out.

Real reviews from diesel truck owners running our delete kits every day.

  • "Spent $4,200 on a DPF replacement last year. Wish I found these guys sooner. Truck runs better than it did off the lot and I'm done throwing money at that emission garbage."
    Mike R. — Texas
  • "Was about to trade in my 6.7 because the repairs were bleeding me dry. Got the full delete and custom tune, now I'm getting 22 MPG and zero codes. Should've done this three years ago."
    Jason T. — Ohio
  • "Dealership quoted me $7,500 for EGR and DPF work. Called TrueAmericanDiesel instead. Paid a fraction, got more power, and haven't seen a check engine light since. No brainer."
    Travis M. — Florida
  • "I tow heavy for work and the regens were killing me mid-haul. Since the delete, my truck actually performs the way it should. More power, better fuel economy, no interruptions. These guys know what they're doing."
    Chris D. — Montana
  • "Skeptical at first but the free custom tune sold me. Drove 200 miles to get it done and I'd do it again. Truck feels like a completely different machine. Real performance, no BS."
    Brandon L. — Arizona
  • "Three DPF cleanings in two years. I was done. Got the delete and tuned, and my truck finally runs like I always thought it should. More throttle response, better mileage, and my wallet's not hurting anymore."
    Derek W. — Oklahoma

Each bundle includes a DPF/CAT delete pipe (mandrel-bent stainless steel), EGR block-off plates & gaskets, DEF delete components, and a preloaded tuner with custom delete tunes built for your exact truck. All mounting hardware, clamps, and a step-by-step installation guide are included. Everything you need — nothing you don't.
Our tunes are built in-house by engineers who've worked with Cummins, Duramax, and Powerstroke platforms for years. No outsourced files, no generic tunes. Every tune is built specifically for your truck's year, engine, and setup — optimized for your driving style.
Because it doesn't cost us much to adjust per vehicle once the base files are built, so why charge you? We'd rather give you the best experience possible and earn your trust — and your referral. Simple as that.
Most of our customers install in their own garage with basic hand tools. We send a step-by-step installation video to your email after purchase, and our support team is a phone call away if you get stuck. Average install time is 2–4 hours.
Orders ship within 1-2 business days. Free express shipping to anywhere in the USA. Most orders arrive in 3–5 business days depending on your location.
Absolutely. You get full support from real diesel techs — not a chatbot. Call us at 817-632-3979 or open a support ticket anytime. We help with installation questions, tune adjustments, troubleshooting, and anything else you need. We don't disappear after the sale.
All bundles include a warranty on parts. If something doesn't fit or function correctly, we make it right — no runaround, no hassle. Contact us and we'll take care of it.
