Featured diesel truck delete kits give you the power, fuel economy, and reliability upgrades your truck deserves. We stock complete solutions for 6.4L Powerstroke, 6.7L Cummins, and Duramax LML engines. Shop our top-rated kits now.

Complete Delete Kits for Ford, Ram & Chevy Diesel Trucks

You've got a diesel engine that's engineered to run hard. Factory emissions systems—DPF (diesel particulate filter), EGR (exhaust gas recirculation), and SCR (selective catalytic reduction)—rob your truck of performance and cost serious money to maintain. Our featured delete kits eliminate these restrictions so your engine breathes, runs cooler, and delivers the efficiency you paid for.

Ford Powerstroke Delete Kits (6.4L & 6.7L)

The 2008-2010 6.4L Powerstroke earned a reputation for DPF clogs and turbo lag. Our Ford 6.4 Powerstroke delete kit and full delete bundle strip away the headaches. For newer setups, the 2011-2019 6.7L Powerstroke and 2015-2019 models benefit from complete EGR and DPF removal. You'll see noticeable power gains and eliminate those expensive regen cycles.

Ram Cummins Delete Solutions (6.7L)

Cummins engines respond immediately to delete kit upgrades. Whether you're running a 2007-2018 platform or the tighter 2013-2018 window, our Ram Cummins 6.7 delete kits handle the job. The DPF & CAT delete pipe for 2007.5-2012 6.7L Cummins addresses the most common restriction points, improving exhaust flow and turbo response.

GM Duramax LML Delete Kit (6.6L)

The 2011-2016 Duramax LML deserves better than factory emissions choking it out. Our GM/Chevy Duramax 6.6 LML delete kit removes the DPF and EGR system entirely, giving you back the horsepower and torque this engine was built for.

How to Choose Your Delete Kit

Match your truck's year range exactly—emissions hardware varies by model year, and fitment is critical. If you're unsure between similar kits, check your VIN's production date. Also explore our turbo upgrades and exhaust systems to maximize your delete investment. Many customers pair delete kits with ECU tuning for full potential.

Will a delete kit hurt my truck's resale value?

It depends on your market and buyer. Enthusiasts and commercial operators value delete kits. Street-legal considerations matter—if your truck gets inspected in an emissions state, you may need to reverse modifications. Always check local regs before installation.

Do I need to tune my truck after installing a delete kit?

A delete kit alone improves airflow and reduces backpressure, but you won't access full potential without a tune. EGR and DPF removal changes your engine's operating parameters. An ECU tune optimizes fuel timing, boost, and fueling for real horsepower and efficiency gains.

What's the difference between a delete kit and a delete pipe?

A full delete kit removes multiple emissions components (DPF, EGR, DEF lines, sensors). A delete pipe—like our DPF & CAT delete pipe—targets one section. For maximum results, go with a complete kit. Delete pipes suit customers wanting targeted fixes or budget solutions.

Will the check engine light come on after a delete?

Yes, without a tune. Removing DPF and EGR sensors triggers codes because the ECU expects those signals. A quality ECU tune disables these monitors and prevents warning lights. Never run a delete kit untuned on the street—you'll light up the dash and risk inspection failures.

How much power does a delete kit actually add?

Kits alone add 15-25 hp by reducing exhaust restriction and lowering EGT (exhaust gas temperature). Pair it with tuning, and you're looking at 50-100+ hp gains depending on your engine. 6.7L Powerstroke and Cummins engines respond especially well. Real-world results vary with fuel quality and driving conditions.

Are delete kits legal for street trucks?

Federal law prohibits removing emissions equipment on highway vehicles. Many states enforce this strictly; others don't. Off-road and competition trucks operate in gray zones. Before buying, check your state's DOT and EPA regulations. Deleted trucks may fail inspections in emissions-tested areas.

Which delete kit is best for towing?

All of them help, but the 6.7L Cummins and 6.7L Powerstroke kits show the biggest towing gains. Reduced EGT and improved turbo response mean cooler, more efficient hauling. Pair your delete with quality fuel and a good tune for the best experience under load.
