5.9L Cummins ISB Delete Kit: Full Guide for Pre-2007 Trucks
If you own a pre-2007 Dodge Ram 2500 or 3500 with the 5.9L Cummins under the hood, you already know what the rest of the diesel world keeps rediscovering: this engine doesn't quit. Trucks that should've been retired at 200,000 miles are still towing, hauling, and running strong past the half-million mark.
But even the 5.9L has one emissions-related weak point — the EGR system added to 2004.5–2007 common rail trucks. This guide covers what's actually on these trucks, what a delete kit addresses, how installation works, and what you can expect in real-world gains for off-road and competition use.

6.7 Cummins CCV Reroute Guide: Stop Blow-By Before It Kills Your Turbo
If you've been running a 6.7 Cummins for a while, you already know this engine is a workhorse. It hauls, it tows, and it keeps pulling long after most gas trucks tap out.

This guide breaks down exactly how the 6.7 Cummins CCV system works, why it's a problem under real-world loads, what a CCV reroute kit does, and how to install one step-by-step. If you're already running or planning an EGR delete, we'll cover why pairing it with a CCV reroute is the smart play.

If you own a Ram 2500 or 3500 powered by the 6.7 Cummins, you already know this engine is a workhorse. It pulls trailers, hauls payload, and racks up miles that would destroy most gas engines.

2004.5–2005 LLY Duramax Buyer's Guide: Specs, Common Problems & Best Upgrades
If you've been shopping for a used heavy-duty Chevy Silverado or GMC Sierra and landed on a 2004.5–2005 model, there's a good chance you're looking at a 6.6L LLY Duramax under the hood. Honestly, that's not a bad place to be. The LLY sits in an interesting spot in Duramax history: more accessible and serviceable than the LB7 that preceded it, but without the complex emissions burdens that started piling on with the LMM and beyond. No DPF. No DEF. No regen cycles eating your fuel mileage. Just a straightforward 6.6L diesel that, with the right upgrades and maintenance, can haul heavy and keep running well past 300,000 miles.
But the LLY isn't without its quirks. This guide covers everything you need to know before buying, maintaining, or building one. We will walk from factory specs and known failure points to the smartest upgrades you can make for performance and long-term reliability.

Common 6.7 Powerstroke DPF Problems and Upgrade Paths
If you own a 2011–2024 Ford Super Duty, odds are you've already had a conversation with your DPF, usually the kind that starts with a dashboard light and ends with a shop quote. The 6.7L Powerstroke is one of the strongest diesel platforms Ford has ever built, but its emissions hardware is also one of the most common reasons these trucks end up in the bay. Regen cycles that never finish, cracked filters, oil dilution, and limp mode all trace back to the same place.
This guide breaks down how the DPF works on the 6.7, the failure modes owners run into most often, how to diagnose them, and the repair and upgrade paths that actually solve the problem instead of just resetting the clock.

2007.5-2010 LMM Duramax Buyer's Guide
If you are in the market for a used heavy-duty Chevy Silverado or GMC Sierra 2500HD/3500HD, the 2007.5 to 2010 LMM Duramax is likely on your radar. Following in the legendary footsteps of the revered LBZ, the 6.6L LMM Duramax shares the same robust architecture, the same bulletproof Allison 1000 6-speed transmission, and the same aggressive V8 grunt. But there's a catch: the LMM marked the official dawn of the modern emissions era for General Motors.
To meet stringent EPA regulations introduced in mid-2007, GM strapped a Diesel Particulate Filter (DPF) and a heavily revised Exhaust Gas Recirculation (EGR) system onto the LBZ's bones, creating the LMM. While the engine itself is a powerhouse, these early bolt-on emissions systems became the Achilles' heel of an otherwise stellar drivetrain.
Whether you're looking to buy your first LMM, or you already own one and want to know how to bulletproof it for the next 200,000 miles, you are in the right place. In this comprehensive buyer's guide, we are breaking down exactly what fails, why it happens, and how the right 2007.5-2010 LMM Duramax parts can transform this choked-up workhorse into a reliable tow rig.

Ford Diesel Engines to Avoid: Problem Years, Common Issues
If you're shopping for a used Ford diesel pickup, you've probably already heard some horror stories. Maybe a buddy dropped $8,000 into a Super Duty he paid $15,000 for. Maybe you've seen forum threads that go on for 200 pages about coolant in the oil. There's a reason those threads exist, and it's not bad luck.
Ford has built some genuinely excellent diesel engines over the years. But it has also produced a few that have become legends for all the wrong reasons. Before you hand over a check for that used F-250 or F-350, here's what you need to know.

Duramax Delete Kit Buyer's Guide: Everything You Need to Know
If you've owned a 6.6L Duramax long enough, you already know the drill. The DPF clogs. The EGR cooler cracks.

At some point, every serious Duramax owner starts asking the same question: what's in a delete kit, and which one do I actually need?
This guide breaks it all down by generation (LBZ, LMM, LML, and L5P) so you can shop with confidence and stop guessing.

If you're running a 2013–2018 Ram 2500 or 3500 with the 6.7L Cummins, you already know what this engine is capable of.

Whether you're a daily driver, a serious tower, or running your truck off-road full time, this is the guide before you buy.

6.7 Cummins Delete Kit Buyer's Guide: Everything You Need Before You Buy
If you've been running a 6.7 Cummins for any length of time, you already know the drill. The truck pulls hard, tows well, and gets respectable fuel economy — until the emissions system starts throwing codes. Whether it's a clogged DPF, a failed EGR cooler, or a DEF pump that decides to quit at 120,000 miles, the downstream costs add up fast. A complete delete kit is how most Cummins owners take back control of their truck and stop feeding the dealership's service department.
This guide breaks down exactly what's in a full 6.7 Cummins delete kit, which parts apply to your year, what kind of performance gains you can realistically expect, and how to pick the right setup for your build.

6.7 Powerstroke EGR Problems: Symptoms, Causes, and Fixes
If you own a Ford Super Duty with the 6.7L Powerstroke diesel, there's a good chance you've already dealt with an EGR problem, or you will.

Whether you're chasing a rough idle, a disappearing coolant level, or a check engine light flashing P0401, this guide covers everything you need to diagnose, repair, or permanently fix your 6.7 Powerstroke EGR problems.

2020-2024 6.7 Powerstroke Delete Kit Buyer's Guide
If you're driving a 2020-2024 Ford Super Duty with the 6.7L Powerstroke, you already know these trucks are built to haul.

That's exactly why more and more 2020+ Powerstroke owners are researching delete kits tailored for their specific model year.
This guide breaks down everything you need to know before buying a 2020-2024 6.7 Powerstroke delete kit: what's in the kit, how it fits your truck, what's genuinely harder on the newer platform, and what kind of performance gains you can realistically expect on the dyno and on the road.

2011–2019 6.7 Powerstroke Delete Kit Buyer's Guide
If you're running a 2011–2019 Ford F-250, F-350, or F-450 Super Duty with the 6.7L Powerstroke diesel, you already know this engine was built to work. What it wasn't built for was years of abuse from its own emissions hardware. DPF regens that cook the turbo. EGR coolers that crack and push coolant into the intake. DEF systems that throw fault codes in freezing weather. A failing emissions stack doesn't just cost you money, it kills tow confidence and eats into the engine life you paid for.
This guide walks you through everything you need to know before buying a 2011–2019 6.7L Powerstroke delete kit: what each emission system does, what a complete kit includes, how to match the right kit to your exact model year, and what kind of performance gains you can realistically expect.

The 2003-2004 Dodge Ram equipped with the 5.9L Cummins marked a watershed moment in diesel truck history. These were the first model years to ditch the old mechanical P7100 injection pump in favor of a Bosch CP3 high-pressure common rail (HPCR) fuel system — and that one change rewrote the rules for what a diesel pickup could do. Whether you're shopping for one of these trucks right now or already own one and want to get the most out of it, this guide covers everything you need to know: factory specs, known weak points, maintenance intervals, and the upgrades that actually move the needle.
