About Us

Built on Records. Driven by Precision.

At JeliBuilt Performance, we don’t just sell parts—we define what the 7.3L platform is capable of.

The Legacy

Founded in 2017 by Brian Jelich, JeliBuilt is the result of over 20 years in the 7.3L community and 15+ years behind the keyboard mastering custom tuning. We aren't just enthusiasts; we are pioneers who have spent decades pushing the limits of diesel technology.

The JeliBuilt Difference

Custom, Clean, Capable.

Brian is an advocate for clean diesel performance, focusing on extracting maximum power while maintaining the integrity and efficiency of your build.

The Proof is in the Trap Speed

Our shop truck, the legendary Ron Burgundy, isn't just a showpiece—it’s a record-setter.

  • 1000 HP Pioneer: In 2011, Ron was the first 7.3L to break the 1000 HP barrier on a chassis dyno.
  • Current Stats: Pushing the envelope further than ever, Ron has clocked a blistering 5.27 @ 133 MPH in the 1/8 mile.

Whether you are looking for a reliable daily driver, tow rig or a dedicated track monster, we bring the same championship-level scrutiny to every file we write and every part we sell.
