"Rolling coal and crushing souls." Boss Ross Diesel: unapologetically overboosted.

More boost, less excuses.

We don't chase horsepower, we drag it -- screaming out of your mill.

Built for torque, tuned for trouble.

From farm trucks to track monsters—we make 'em all spool happy.

Lift it, lock it, launch it—regret nothing.

Built to crawl over rocks, mall curbs optional.

Turning daily drivers into trail survivors—one questionable mod at a time.

We put the ‘overkill’ in overland. Boss HP —where mild upgrades go to die.

If it ain’t broke, you’re not pushing hard enough.

Built to tow your house, and scare your neighbors.

Making smoke signals since… well, since your last tune.
