  • CUMMINS HISTORY, LESSON 2: ’94-’98 5.9L

    Thanks to its reputation for making cheap, easy horsepower, its anvil-like construction, long-term durability and simplistic nature, the ’94-’98 12-valve 5.9L Cummins remains one of the most highly sought after engines in the diesel world. In many ways it was similar to the original ’89-’93 5.9L, sharing the same block, head, rods and displacement. However, its biggest difference would be what made it so legendary: the Bosch P7100 (i.e. the P-pump). Believe it or not, the P-pump was introduced so the 5.9L could meet 1994 emission standards set to take effect on January 1, 1994.

  • Why is the 6BT 12 Valve Considered the best of all diesels?

    From Jalopnik.com:

    “The most reliable, simplest, as basic-as-it gets, fully-mechanical diesel engine” a diesel tuner could ever ask for; in fact, the vehicle literally only needed a couple wires to turn the motor over with a starter; and once it was running, the engine needed no electronics at all. Compare that to the bag of snakes all modern engines have under hood, and you realize just how simple this motor is.”

  • 11 Reasons Why The 12-Valve Cummins Is The Ultimate Diesel Engine

    A simple design with unmatched reliability, tremendous performance potential and rugged, million-mile durability sums up the appeal of the 12-valve 5.9L 6BT Cummins. To thousands of diesel lovers, this 1,100-pound hunk of iron is the patriarch of the modern diesel performance era. The ¾-ton and 1-ton Dodge Rams they grace can be made to produce 500 rwhp with relative ease, rack up more than 20 mpg on the highway and easily last more than a half a million miles. In addition to being the power plant of choice in the truck pulling game, the 12-valve is a regular choice in the engine swap world as well, powering countless Jeep, rat rod, muscle car and dragster projects. But exactly why is a 20-year-old diesel — straddled with ancient injection technology — so high on everyone’s priority list? Scroll along as we pinpoint all of its strong suits. From free horsepower to a near-indestructible design, to the immense parts interchangeability that exists across all model years (including on-road, off-highway and marine applications), the following 11 reasons spell out why the 12-valve version of the 5.9L is so legendary.

  • Does Cummins use Chinese parts?

    The Chinese government does not allow foreign companies to own any business outright in their country. They do allow companies to have facilities as long as a Chinese business controls at least 50% ownership.

    So, the next time you see a Genuine Cummins box or bag with English AND Chinese writing on them rest assured you are indeed buying a Cummins Original Equipment Manufactured part.
