Are you looking to totally refresh your Cummins and get it running like new again? Start with the confidence that it’s done right the first time. The Essential Short Block from D&J is designed for people who rely on their truck, whether they tow, use it for work, or just need a dependable engine. Instead of patching together a questionable bottom end, this gives you a fully remanufactured, precision-built base that restores compression, oil control, and overall engine integrity.

The real value here is peace of mind. You’re getting a clean, properly machined starting point that eliminates the guesswork and risk that comes with high-mileage cores or junkyard pulls. It’s built to handle daily driving and workload demands with consistency, giving you a solid platform whether you’re keeping it stock or planning for big power. When reliability matters more than anything, this is the kind of foundation that keeps your truck on the road.

Each short block is completely torn down, thoroughly inspected, and precision-machined using CNC blueprinting processes to restore all critical tolerances to OEM spec. The block is bored, honed, and decked, while components like the crankshaft, rods, and pistons are carefully measured and corrected to ensure proper clearances throughout. Critical areas are checked for cracks, straightness, and wear, with every dimension from piston-to-wall clearance to bearing tolerances verified before assembly.

Assembly is performed by skilled technicians using new internal components, such as pistons, bearings, and gaskets, to ensure long-term durability and consistent performance. The result is a short block that delivers factory-level reliability, with the added benefit of precise machining and quality control, built to withstand real-world use where longevity and structural integrity are critical.

Cleans Out Working Carburetors
Size: 2 fl oz
I recommend this product for engines that will in fact start but not run well. I highly recommend it for that specific purpose, which it is designed for. It cleans the inner workings of the carburetor. Of course, you will have a cleaner carburetor if you take it apart and clean it with proper tools and a proper carburetor cleaner. You spray it in the gas tank, start the engine, and let it run a bit. It will not start an engine with a totally plugged up carburetor. Nothing is going to do that. Nor is it a fuel stabilizer, as one previous reviewer seemed to think. Nor is it a product to be used to bring life back to stale gasoline, as another reviewer seemed to think. The only thing to do with stale gasoline is drain it out and pitch it. Nor is it a product to be used for cleaning a carburetor you have taken apart to clean. You should use a proper carburetor cleaner for that purpose. I've given it four stars because it cleans out mildly plugged up carbs. It is not a miracle solution for really neglected carbs as the name suggests.

It works like magic, saved me $150.
Size: 2 fl oz
I filled 1/4 tank of gas into my snowblower which I could not started, sprayed about 15 seconds of Start Your Engines, rock snowblower to mix well, let it sat for an hour. I pulled string and yet couldn't start engine. Unscrewed spark plug and spray some into cylinder, put the spark plug back and pull the string. ENGINE STARTED!!! SAVED ME AT THE LEAST $150.
