At JeliBuilt Performance, we don’t just sell parts—we define what the 7.3L platform is capable of.
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.
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.
Our shop truck, the legendary Ron Burgundy, isn't just a showpiece—it’s a record-setter.


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.
From our shop to the world: We are proud to serve a global community of 7.3L owners, providing custom tuning and elite performance parts from the industry's most trusted manufacturers.
