Our Story
Welcome to Screamin' Seeman Off Road
For years, I worked on my own projects and helped others with theirs. Along the way, I kept running into situations where the part I needed either didn't exist, was poorly designed, or was very poorly fabricated.
So I started making my own.
What started as a few one-off parts for personal projects slowly grew into something more. Friends wanted them. Then friends of friends. Before long, parts were being shipped all over the country.
Today, SSOR offers a variety of products for enthusiasts, mechanics, and do-it-yourselfers. Every product started as a solution to a problem and was developed with the same standards I'd expect on my own projects.
If you're here, chances are you're working on a project of your own. I hope you'll find a solution that saves you some time and frustration.

The Right Way to Swap a Cummins
Cummins swaps aren't complicated because of the engine—they're complicated because of everything that surrounds it. Engine mounts, crossmembers, adapters, brackets, wiring, and countless details can turn a straightforward swap into a major project.
SSOR develops durable, well-engineered Cummins conversion components for GM trucks, with an emphasis on strength, fitment, and attention to detail. Built from real-world experience and tested on actual swaps.
- Designed from real-world swap experience
- Engineered for strength, fitment, and serviceability
- Fabricated with uncompromising attention to detail
- Built to solve problems—not create new ones
