At Alligator Performance, we don’t just stock parts—we partner with brands that earn their way into the diesel world with grit, quality, and unwavering commitment to performance. That’s why we’re excited to announce a new addition to the Alligator family: DFC Diesel, one of the most respected names in diesel engine remanufacturing.

These folks don’t mess around. DFC Diesel specializes in high-performance, remanufactured long blocks for Cummins, Power Stroke, and Duramax platforms. And when we say “remanufactured,” we’re not talking about a quick hone and slap-together rebuild. We're talking full-engine precision machining, brand-new components, and a process that pushes past OEM specs to deliver a powerplant that’s ready to handle work, play, and everything in between.

Why We’re All-In on DFC

When we first looked at DFC’s lineup, it was clear they had something special: buildable, bulletproof long blocks that give serious diesel owners the foundation to go stock, go wild, or go to work.

Every DFC engine is remanufactured to incredibly tight tolerances using Rottler CNC machining. That means every bore, deck, and line hone is machined not just to factory spec—but often better than factory. And it’s not just about machining. These long blocks come loaded with top-tier components from brands like Mahle and Total Seal, ensuring these engines are ready for whatever you throw at them.

But here’s the kicker: DFC doesn’t just talk the talk. Every long block is backed by an industry-leading 5-year, 100,000-mile warranty (160,000 km for our Canadian friends), offering you serious peace of mind. You’re not just buying an engine—you’re buying confidence.

What’s Available Right Now (And What’s Coming Soon)

We’re already updated and ready to roll with two of the most in-demand platforms:

• 1994-1998 Dodge Ram 5.9L 12V Cummins Long Blocks

These legendary Cummins powerplants are now available through Alligator Performance with the DFC touch—fully remanufactured, dyno-tested, and ready to drop into your build. Whether you’re working the oil fields or chasing quarter-mile times, these long blocks offer the perfect base for your dream truck.

And that’s just the beginning.

Literally, if you’ve got an American-made oil burner, Alligator Performance and DFC has you covered with high-performance long blocks for your truck.

Why Diesel Builders Love DFC Long Blocks

Ask any serious diesel builder what they want in a long block, and you’ll hear the same things: reliability, consistency, upgrade potential, and support. DFC delivers on all fronts.

These long blocks are ideal for:

• Tow rigs pulling fifth wheels or trailers across the country
• Work trucks clocking high mileage under load
• Performance builds looking for a clean slate to build boost-ready power
• Daily drivers who want OEM+ dependability with long-term (100,000 miles!) warranty protection

Whether you’re adding compounds, upgrading injectors, or just looking to replace a tired stock engine with something stronger, DFC gives you the breathing room to do it—without cutting corners or compromising your build.

Built in Canada. Trusted Everywhere.

Headquartered in Edmonton, Alberta, DFC Diesel has built a reputation as one of the most trusted engine remanufacturers in North America. Their reputation isn’t just earned on a bench—it’s proven every day by the thousands of engines they’ve put back on the road.

So yeah—we’re pumped to welcome DFC into the Alligator lineup. You don’t build a brand like theirs overnight. You do it by doing the hard stuff right, over and over again.
